Description

CONTACT LENS PACKAGES HAVING AN ABSORBENT MEMBER

I. BACKGROUND OF THE INVENTION

In a conventional contact lens package, the contact lens typically sits in a molded plastic base having a cavity (or "bowl") that houses the contact lens in a concave-side-up orientation. As a result, the user experience for transferring a contact lens from the package to an eye generally involves the user "fishing" the contact lens out of the bowl with a finger and then flipping the lens so that it is in the correct orientation on the finger for placement on the eye. This process requires touching the lens multiple times, which can transfer contaminants or pathogens from the hand to the lens and ultimately to the eye. Not only is this handling experience unsanitary, but it is also unduly cumbersome, messy, and mechanically stressful to the lens, which can tear, rip, or distort when overly manipulated. While some packages have been designed to present the lens in a convex-side-up orientation to obviate the need for flipping the lens, they often still require the lens to be "fished" from the packaging solution or otherwise necessitate manipulation of the lens and/or multiple touches of the lens to achieve transfer of the lens to the eye.

In view of the growing awareness around ocular health and the customer demand for a more convenient experience, a need has arisen for contact lens packaging that enables a less messy and more sanitary contact lens handling process. The solution in which the lens is packaged can affect the releasability of the lens from the packaging and the finger. That is, liquid solution in the bowl makes removal of the lens from the bowl more difficult because a hydrophilic lens with excessive liquid reduces surface tension between the human finger and the lens, making adequate adhesion between the lens and the finger difficult to achieve, making it difficult to remove the lens from the package.

Among other considerations, it would be desirable for wearers to be able to drain away any packaging solution which might impact the ability of adhering the lens to the finger, as variation in the amount of packaging solution adhering to the lens and package can impact the process of placing the lens on the finger. A mechanism for efficient draining of packing solution from the lens within the package prior to taking the lens from an opened contact lens package onto a user's finger can aid in the removal and insertion process.

There remains a need for contact lens packages which provide a mechanism for consistent draining of solution away from the contact lens.

II. SUMMARY

It has now been found that some or all the foregoing and related objects may be attained in a contact lens package having one or more aspects described herein. According to certain embodiments, a contact lens package can include a first cavity that houses a contact lens and packaging solution, and a second cavity that houses an absorbent member. As described herein, in some embodiments, the first cavity and the second cavity may be in fluid isolation from one another when the package is in an unopened state, and the first cavity and the second cavity may be in fluid communication with one another when the package is transitioned from the unopened state to an opened state. In certain embodiments, the package may be configured such that at least a portion of, and in some instances, a majority of, the packaging solution flows from the first cavity into the second cavity when the package is transitioned from the unopened state to the opened state. In this manner, as described herein, the absorbent member may be configured for absorbing at least a portion of, and in some instances, a majority of, the packaging solution when the package is transitioned from the unopened state to the opened state. In some embodiments, the flow of the packaging solution from the first cavity into the second cavity when the package is transitioned from the unopened state to an opened state may result in a significant amount of the packaging solution being drained away from the contact lens, thereby improving the ability to adhere the lens to the user's finger for removal from the package and placement onto the user's eye. Moreover, the inclusion of the absorbent member within the second cavity of the package may improve user experience by reducing spillage of packaging solution associated with opening the package, as a significant amount of the solution may be absorbed and contained by the absorbent member. The present disclosure provides various embodiments of contact lens packages, methods of packaging a contact lens, and methods of opening a contact lens package.

Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings wherein reference numerals indicate certain elements. The following descriptions are not intended to limit the myriad embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims.

References to "one embodiment," "an embodiment," "some embodiments," "an example embodiment," etc., indicate that the embodiment described may include a particular feature, structure, aspect, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, aspect, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to effect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.

Lens(es) or contact lens(es) refer to ophthalmic devices that reside on the eye. They have a generally hemispheric shape and can provide optical correction, cosmetic enhancement, UV blocking and visible light or glare reduction, therapeutic effect, including wound healing, delivery of drugs or neutraceuticals, diagnostic evaluation or monitoring, or any combination thereof. The term lens includes soft hydrogel contact lenses, which are generally provided to the consumer in a package in the hydrated state, and have a relatively low moduli, which allows them to conform to the cornea. Contact lenses suitable for use with the packages of the present invention include all hydrated contact lenses, including conventional and silicone hydrogel contact lenses.

A hydrogel is a hydrated crosslinked polymeric system that contains water in an equilibrium state, and may contain at least about 25%, or at least 35% water in the hydrated state. Hydrogels typically are oxygen permeable and biocompatible, making them excellent materials for producing contact lenses.

Conventional hydrogel contact lenses do not contain silicone containing components, and generally have higher water content, lower oxygen permeability, moduli, and shape memories than silicone hydrogels. Conventional hydrogels are prepared from monomeric mixtures predominantly containing hydrophilic monomers, such as 2-hydroxyethyl methacrylate ("HEMA"), N-vinyl pyrrolidone ("NVP") or polyvinyl alcohols. United States Patents Nos. 4,495,313, 4,889,664 and 5,039,459 disclose the formation of conventional hydrogels. Conventional hydrogels may be ionic or non-ionic and include polymacon, etafilcon, nelfilcon, ocufilcon lenefilcon and the like. The oxygen permeability of these conventional hydrogel materials is typically below 20-30 barrers.

Silicon hydrogel formulations include balafilcon samfilcon, lotrafilcon A and B, delfilcon, galyfilcon, senofilcon A, B and C, narafilcon, comfilcon, formofilcon, riofilcon, fanfilcon, stenfilcon, somofilcon, kalifilcon and the like. "Silicone hydrogels" refer to polymeric networks made from at least one hydrophilic component and at least one silicone-containing component. Silicone hydrogels may have moduli in the range of 60-200, 60-150 or 80 -130 psi, water contents in the range of 20 to 60%. Examples of silicone hydrogels include acquafilcon, asmofilcon, balafilcon, comfilcon, delefilcon, enfilcon, fanfilcon, formofilcon, galyfilcon, lotrafilcon, narafilcon, riofilcon, samfilcon, senofilcon, somofilcon, and stenfilcon, verofilcon, including all of their variants, as well as silicone hydrogels as prepared in US Patent Nos. 4,659,782, 4,659,783, 5,244,981, 5,314,960, 5,331,067, 5,371,147, 5,998,498, 6,087,415, 5,760,100, 5,776,999, 5,789,461, 5,849,811, 5,965,631, 6,367,929, 6,822,016, 6,867,245, 6,943,203, 7,247,692, 7,249,848, 7,553,880, 7,666,921, 7,786,185, 7,956,131, 8,022,158, 8,273,802, 8,399,538, 8,470,906, 8,450,387, 8,487,058, 8,507,577, 8,637,621, 8,703,891, 8,937,110, 8,937,111, 8,940,812, 9,056,878, 9,057,821, 9,125,808, 9,140,825, 9156,934, 9,170,349, 9,244,196, 9,244,197, 9,260,544, 9,297,928, 9,297,929 as well as WO 03/22321, WO 2008/061992, and US 2010/0048847. These patents are hereby incorporated by reference in their entireties. Silicone hydrogels may have higher shape memory than conventional contact lenses.

Hydrogel lenses are viscoelastic materials. Contact lenses can form optical distortions if the lens interacts with either the package or any air bubble in the package. The extent of the optical distortions, and the length of time needed for the distortions to relax out will vary depending on the chemistry, and to a lesser extent, geometry of the lens. Conventional lens materials, such as poly hydroxyethyl methacrylate-based lenses like etafilcon A or polymacon have low loss modulus and tan delta compared to silicone hydrogels and may form fewer and less severe optical distortions as a result of contact with packaging. The incorporation of silicones (which generally increase the bulk elastic response), wetting agents such as PVP (which generally increase the viscous response) or coatings of conventional hydrogel materials (which may lower the elastic response at the lens interface) can alter the lens viscoelastic properties. Conventional hydrogel contact lenses and silicone hydrogel contact lenses having short or stiff crosslinking agents and or stiffening agent have short shape memories and may be less susceptible to deformation during storage. As used herein, high or higher shape memory hydrogels display optical distortions from contact with an air bubble or package of at least about 0.18 after 5 weeks of accelerated aging at 55°C. Viscoelastic properties, including loss modulus and tan delta, can be measured using a dynamic mechanical analysis.

The contact lenses can be of any geometry or power, and have a generally hemispherical shape, with a concave posterior side which rests against the eye when in use and a convex anterior side which faces away from the eye and is contacted by the eyelid during blinking.

The center or apex of the lens is the center of the lens optic zone. The optic zone provides optical correction and may have a diameter between about 7mm and about 10mm. The lens periphery or lens edge is the edge where the anterior and posterior sides meet.

The wetted lens is the contact lens and any residual packaging solution attached to it after packaging solution drainage. Wetted contact is the aggregated contact area between the wetted lens and lens support. Embodiments may include a lens support surrounded by a sealable cavity also interchangeably referred to as a chamber. The cavity may have any convenient form and may comprise a package base and at least a lid, each of which are described in detail below. As used herein, the phrases "the lid", "a lid", "the base" and "a base" encompass both the singular and plural. The lid and package base are sealed to each other to form a cavity which holds the contact lens, support and packaging solution in a sterile state during shipping and storage prior to use. The contact lens package is made from materials which are compatible with the contact lens and solution, as well as retortable and biologically inert.

"Film" or "multilayer film" are films used to seal the package and are often referred to as lidstock. Multilayer films used in conventional contact lens packages may be used in the packages of the present invention as the base, a component of the lid, or both. Multilayer films comprise a plurality of layers, including barrier layers, including foil layers, or coatings, seal layers, which seal the film to the rest of the package, and may also comprise additional layers selected from peel initiation layers, lamination layers, and layers that improve other package properties like stiffness, temperature resistance, printability, puncture resistance, barrier resistance to water or oxygen and the like. The multilayer films form a steam sterilizable (retortable) seal. The multilayer film can include PET, BON or OPP films layers to increase stiffness and temperature resistance, or to EVOH or PVDC coatings to improve barrier resistance to oxygen or moisture vapor.

An "unopened state" or "unopened" as used herein refers to a contact lens package that is closed and houses a contact lens in solution. An "opened state" or "opened" as used herein refers to a contact lens package after the sterile seal has been broken. Depending on the context described herein, the opened state extends to the state of the package when the user has manipulated the package to cause the lens to be lifted out of the packaging solution for transfer by the user.

A "wearer" or "user" as used herein refers to a person opening a contact lens package. The user is generally referred to as the person who both opens the package and transfers the contact lens contained therein to their eye. However, the user in some contexts may be a person handling the lens package on behalf of the wearer, such an eye care provider ("ECP") or another individual demonstrating for or assisting the wearer.

Packaging solution is any physiologically compatible solution, which is compatible with the selected lens material and packaging. Packaging solutions include buffered solutions having a physiological pH, such as buffered saline solutions. The packaging solution may contain known components, including buffers, pH and tonicity adjusting agents, lubricants, wetting agents, nutraceuticals, pharmaceuticals, in package coating components and the like.

The package base may form the bottom of the package. It can be made from any material suitable for packaging medical devices, including plastic. The packaging lid generally resides at the upper portion the package and seals with the base to form a cavity containing at least a portion of the lens support, lens, and packaging solution. The lid may be made from any material suitable for packaging medical devices, including a molded sheet of foil or plastic, laminate films, or plastic. Packages comprising plastic for one structure and foil or laminated films as the other, or packages comprising foil or laminated films as the outer layer for the lid and base are known in the art and are examples of suitable combinations. References throughout this description to injection molding processes and the use of materials conventionally applied to injection molding should be understood as exemplary. Those of skill in the art will appreciate that other means of manufacture are possible within the scope of the appended claims, including but not limited to alternative molding processes, thermoforming, 3D printing, and the like. Likewise, references to heat seals and heat sealing are exemplary to embodiments described herein. Other means of securing packaging components will be apparent to those skilled in the art, including the use of adhesive, glue, thermal bonding, welding such as heat, ultrasonic or laser welding, or a mechanical trap, and the like.

Certain aspects of the invention may serve to reduce or prevent significant optical damage to the contact lens due to interactions with air bubbles or the interior of the lens package that may arise during storage or transit due to gravitational or other forces, such as mechanical pressure being applied from outside of the package. As used herein, significant optical damage means a root-mean-squared (RMS) value equal or greater than about 0.08pm.

Referring now to the drawings, FIGS. 1A-1D illustrate an example contact lens package 100 in accordance with embodiments of the present disclosure. As described, the contact lens package 100 may include a base 110, a lid 150, a contact lens 160, packaging solution 170, and an absorbent member 180. The contact lens package 100 may have an unopened state, as shown in FIGS. 1A and 1C, and an opened state, as shown in FIG. ID. When the contact lens package 100 is in the unopened state, the contact lens 160 and the packaging solution 170 may be housed within a first cavity 122 formed between the base 110 and the lid 150, and the absorbent member 180 may be housed within a second cavity 124 formed between the base 110 and the lid 150. As described below, the first cavity 122 and the second cavity 124 may be in fluid isolation from one another when the contact lens package 100 is in the unopened state, which may cause the packaging solution 170 to be disposed about and in contact with the contact lens 160 for maintaining hydration of the lens 160. In this manner, when the contact lens package 100 is in the unopened state, the packaging solution 170 may be contained within the first cavity 122, while the second cavity 124 and the absorbent member 180 contained therein may be devoid of any of the packaging solution 170. When desired, a user may open the contact lens package 100 by at least partially removing the lid 150 from the base 110 to allow access to the contact lens 160. Such opening of the contact lens package 100 may cause the first cavity 122 and the second cavity 124 to be in fluid communication with one another, allowing the packaging solution 170 to flow from the first cavity 122 into the second cavity 124 such that the absorbent member 180 absorbs a significant amount of the packaging solution 170, effectively draining the packaging solution 170 away from the contact lens 160. In this manner, such drainage of the packaging solution 170 away from the contact lens 160 may allow a user to remove the contact lens 160 more easily from the contact lens package 100. The at least partial removal of the lid 150 from the base 110 may expose the contact lens 160, allowing the user to engage and remove the contact lens 150 with the user's finger. As shown, a lens support 130 of the base 110 may maintain a position and orientation of the contact lens 160 within the cavity 122 when the contact lens package 100 is in the unopened state. As shown in FIG. 1C, the contact lens 160 may be housed within the first cavity 122 and supported by the lens support 130 such that a convex surface of the contact lens 160 faces the lid 150 when the contact lens package 100 is in the unopened state. In this manner, when the contact lens package 100 is opened, the user may engage the convex surface for removal of the contact lens 160 and subsequent placement of the contact lens 160 on the user's eye, enabling a streamlined experience and avoiding the drawbacks of certain existing contact lens packages.

According to the illustrated example, the base 110 may have a first end 112 (which also may be referred to as a "back end" in certain embodiments) and a second end 114 (which also may be referred to as a "front end" in certain embodiments) disposed opposite one another. As shown, the base 110 may have a first side 116 (which also may be referred to as a "top side" in certain embodiments) and a second side 118 (which also may be referred to as a "bottom side" in certain embodiments) disposed opposite one another and each extending from the first end 112 to the second end 114. The base 110 also may have a pair of lateral sides 120 disposed opposite one another and each extending from the first end 112 to the second end 114. In some embodiments, as shown, the base 110 may include certain portions having a planar shape and other portions having a contoured shape. In some embodiments, as shown, the base 110 may include a main portion having a planar shape, an absorbent-member support 140 that is recessed relative to the main portion and has a planar shape, and a lens support 130 that extends upward from the absorbent-member support 140 beyond the main portion and has a contoured shape. In some embodiments, as shown, the base 110 may define a first base cavity that forms a portion of the overall first cavity 122 of the contact lens package 100, and a second base cavity that forms a portion of the overall second cavity 124 of the contact lens package 100. In some embodiments, as shown, a barrier 126 of the base 110 may be disposed between the first cavity 122 and the second cavity 124. As discussed above, the base 110 may be formed of any suitable material. In certain embodiments, the base 110 may be substantially rigid. In other embodiments, the base

110 may be flexible. The lens support 130 may at least partially define the first cavity 122 and may support the contact lens 160 in a desired position and orientation within the first cavity 122. As shown, the lens support 130 may extend upward relative to the absorbent-member support 140 and may support the contact lens 160 between the base 110 and the lid 150. In some embodiments, as shown, the lens support 130 may be integrally formed with a remainder of the base 110. In other embodiments, the lens support 130 may be separately formed and connected to the remainder of the base 110. In some embodiments, the lens support 130 may be provided as a separate component that is disposed within the first cavity 122 between the base 110 and the lid 150 and is connected to the base 110, for example, by an adhesive or other means of attachment. As shown, the lens support 130 may include an internal surface 132 (which also may be referred to as a "support surface" in certain embodiments) that engages and supports the contact lens 160 within the cavity 122. In particular, the internal surface 132 may engage the concave surface of the contact lens 160. In some embodiments, the internal surface 132 may be a convex surface, although other shapes of the internal surface 132 may be used in other embodiments. As shown, the lens support 130 may be formed as a dome extending upward from the absorbent-member support 140, and the internal surface 132 may be a convex outer surface of the dome. As shown, the lens support 130 may include an external surface 134 disposed opposite the internal surface 132 and defining an external portion of the contact lens package 100. In some embodiments, the external surface 134 may be a convex surface, with the convex shape thereof facilitating nesting of multiple contact lens packages 100 disposed adjacent one another, such as in a stack, although other shapes of the external surface 134 may be used in other embodiments. The lens support 130 may be formed of any suitable material. In some embodiments, the lens support

130 may be substantially rigid.

The absorbent-member support 140 may at least partially define the second cavity 124 and may support the absorbent member 180 in a desired position and orientation within the second cavity 124. As shown, the absorbent-member support 140 may be recessed relative to the main planar portion of the base 110 and may support the absorbent member 180 between the base 110 and the lid 150. In some embodiments, as shown, the absorbent-member support 140 may be integrally formed with a remainder of the base 110. In other embodiments, the absorbent-member support 140 may be separately formed and connected to the remainder of the base 110. In some embodiments, the absorbent-member support 140 may be provided as a separate component that is disposed within the second cavity 124 between the base 110 and the lid 150 and is connected to the base 110, for example, by an adhesive or other means of attachment. As shown, the absorbent-member support 140 may include an internal surface 142 (which also may be referred to as a "support surface" in certain embodiments) that engages and supports the absorbent member 180 within the second cavity 124. In particular, the internal surface 142 may engage a bottom surface of the absorbent member 180. In some embodiments, as shown the internal surface 142 may be a planar surface, although other contoured shapes of the internal surface 142 may be used in other embodiments. As shown, the absorbent-member support 140 may include an external surface 144 disposed opposite the internal surface 142 and defining an external portion of the contact lens package 100. In some embodiments, the external surface 144 may be a planar surface, although other shapes of the external surface 144 may be used in other embodiments. The absorbent-member support 140 may be formed of any suitable material. In some embodiments, the absorbent-member support 140 may be substantially rigid.

The lid 150 may be connected to the base 110 and may extend over at least part of the base 110. As shown, when the contact lens package 100 is in the unopened state, the lid 150 and the base 110 may seal the contact lens 160 and the packaging solution 170 within the first cavity 122 and may seal the absorbent member 180 within the second cavity 124. In this manner, the base 110 and the lid 150 together may form each of the sealed first cavity 122 for containing the contact lens 160 and the packaging solution 170 and the sealed second cavity 124 for containing the absorbent member 180 until a user desires to open the contact lens package 100 and remove the contact lens 160 for use. In some embodiments, as shown, when the contact lens package 100 is in the unopened state, the lid 150 may extend over and cover the lens support 130, the absorbent-member support 140, and other respective portions of the base 110. When the contact lens package 100 is in the unopened state, respective portions of the lid 150 may be sealed to respective adjacent portions of the base 110, such as the barrier 126 and portions of the main portion of the base 110 surrounding the lens support 130 and the absorbent-member support 140, such that the contact lens 160 and the packaging solution 170 are contained within the first cavity 122 formed by the base 110 and the lid 150, and such that the absorbent member 180 is contained within the second cavity 124 formed by the base 110 and the lid 150. The seal between the lid 150 and the base 110 may be at least partially broken when the contact lens package 100 is transitioned from the unopened state to an opened state for removal of the contact lens 160. As discussed above, the lid 150 may be formed of any suitable material. In certain embodiments, as shown, the lid 150 may be flexible. The absorbent member 180 may be configured for absorbing at least a portion of the packaging solution 170 when the contact lens package 100 is transitioned from the unopened state to the opened state such that the first cavity 122 and the second cavity 124 are in fluid communication with one another. In some embodiments, the absorbent member 180 may be configured for absorbing a majority of the packaging solution 170 when the contact lens package 100 is transitioned from the unopened state to an opened state. In some embodiments, the absorbent member 180 may be compressible and configured for transitioning between a compressed state and an expanded state. In some embodiments, the absorbent member 180 may be biased toward the expanded state. In some embodiments, the absorbent member 180 may be in the expanded state when the contact lens package 100 is in the unopened state. In some embodiments, the absorbent member 180 may be in the compressed state when the contact lens package 100 is in the unopened state, and the absorbent member 180 may transition from the compressed state to the expanded state when the contact lens package 100 is transitioned from the unopened state to the opened state. In this manner, when the contact lens package 100 is in the unopened state, the absorbent member 180 may be compressed between the base 110 and the lid 150 and maintained in the compressed state, and when the contact lens package 100 is transitioned from the unopened state to an opened state, the absorbent member 180 may automatically transition from the compressed state to the expanded state. As discussed above, such transitioning of the absorbent member 180 from the compressed state to the expanded state may allow the absorbent member 180 to quickly absorb the packaging solution 170, thereby further facilitating drainage of the packaging solution 170 away from the contact lens 160. In some embodiments, the absorbent member 180 may be formed of or may include a sponge. In some embodiments, the absorbent member 180 may be formed of or may include a foam. In some embodiments, the absorbent member 180 may be formed of or may include a superabsorbent polymer. Various other suitable configurations and materials may be used for the absorbent member 180.

FIGS. 1C and ID illustrate an example method of opening the contact lens package 100 in accordance with embodiments of the present disclosure. As noted above, the contact lens package 100 may be provided and stored in the unopened state, as shown in FIGS. 1A and 1C, until a user desires to open the package 100. With the contact lens package 100 in the unopened state, the user may hold the base 110 and grasp an end region of the lid 150, such as the end region of the lid 150 that is not directly connected to the base 110, as shown in FIG. 1C. The user may at least partially remove the lid 150 from the base 110 by pulling the end region of the lid 150 away from the base 110. In this manner, at least a portion of the seal between the lid 150 and the base 110 may be broken. As shown in FIG. ID, the lid 150 may be removed from the base 110 such that the contact lens 160, the lens support 130, and at least a portion of the absorbent member 180 are no longer covered by the lid 150. In some embodiments, as shown, the entirety of the absorbent member 180 may be exposed. In some embodiments, the lid 150 may be entirely removed from the base 110. As discussed above, the lid 150 may be at least partially removed from the base 110 such that the first cavity 122 and the second cavity 124 are in fluid communication with one another, thereby allowing at least a portion of the packaging solution 170 to flow from the first cavity 122 into the second cavity 124 and be absorbed by the absorbent member 180 and drained away from the contact lens 160. After at least partially removing the lid 150 from the base 110, as shown in FIG. ID, the user may engage the contact lens 160 while the contact lens 160 is exposed and supported by the lens support 130. According to the illustrated embodiment in which the lens support 130 supports the concave surface of the contact lens 160, the user may engage the convex surface of the contact lens 160 and remove the contact lens 160 from the lens support 130. As discussed above, by allowing at least a portion of the packaging solution 170 to drain away from the contact lens 160 and be absorbed and contained by the absorbent member 180, the user may be able to easily engage and retain the contact lens 160 with the user's finger. In this manner, the contact lens 160 may be conveniently removed from the lens support 130 and held on the user's finger in the desired concave-side-up orientation, ready for positioning on the user's eye.

FIGS. 2A-2D illustrate another example contact lens package 200 in accordance with embodiments of the present disclosure. As described, the contact lens package 200 may include a base 210, a lid 250, a gate 252, a contact lens 260, packaging solution 270, and an absorbent member 280. The contact lens package 200 may have an unopened state, as shown in FIGS. 2A and 2C, and an opened state, as shown in FIG. 2D. When the contact lens package 200 is in the unopened state, the contact lens 260 and the packaging solution 270 may be housed within a first cavity 222 formed between the base 210 and the lid 250, and the absorbent member 280 may be housed within a second cavity 224 formed between the base 210 and the lid 250. As described below, the first cavity 222 and the second cavity 224 may be in fluid isolation from one another when the contact lens package 200 is in the unopened state, which may cause the packaging solution 270 to be disposed about and in contact with the contact lens 260 for maintaining hydration of the lens 260. In this manner, when the contact lens package 200 is in the unopened state, the packaging solution 270 may be contained within the first cavity 222, while the second cavity 224 and the absorbent member 280 contained therein may be devoid of any of the packaging solution 270. When desired, a user may open the contact lens package 200 by at least partially removing the lid 250 from the base 210 to allow access to the contact lens 260. Such opening of the contact lens package 200 may cause the first cavity 222 and the second cavity 224 to be in fluid communication with one another, allowing the packaging solution 270 to flow from the first cavity 222 into the second cavity 224 such that the absorbent member 280 absorbs a significant amount of the packaging solution 270, effectively draining the packaging solution 270 away from the contact lens 260. In this manner, such drainage of the packaging solution 270 away from the contact lens 260 may allow a user to remove the contact lens 260 more easily from the contact lens package 200. The at least partial removal of the lid 250 from the base 210 may expose the contact lens 260, allowing the user to engage and remove the contact lens 250 with the user's finger. As shown, a lens support 230 of the base 210 may maintain a position and orientation of the contact lens 260 within the cavity 222 when the contact lens package 200 is in the unopened state. As shown in FIG. 2C, the contact lens 260 may be housed within the first cavity 222 and supported by the lens support 230 such that a convex surface of the contact lens 260 faces the lid 250 when the contact lens package 200 is in the unopened state. In this manner, when the contact lens package 200 is opened, the user may engage the convex surface for removal of the contact lens 260 and subsequent placement of the contact lens 260 on the user's eye, enabling a streamlined experience and avoiding the drawbacks of certain existing contact lens packages.

According to the illustrated example, the base 210 may have a first end 212 (which also may be referred to as a "back end" in certain embodiments) and a second end 214 (which also may be referred to as a "front end" in certain embodiments) disposed opposite one another. As shown, the base 210 may have a first side 216 (which also may be referred to as a "top side" in certain embodiments) and a second side 218 (which also may be referred to as a "bottom side" in certain embodiments) disposed opposite one another and each extending from the first end 212 to the second end 214. The base 210 also may have a pair of lateral sides 220 disposed opposite one another and each extending from the first end 212 to the second end 214. In some embodiments, as shown, the base 210 may include certain portions having a planar shape and other portions having a contoured shape. In some embodiments, as shown, the base 210 may include a main portion having a planar shape, an absorbent-member support 240 that is recessed relative to the main portion and has a planar shape, and a lens support 230 that extends upward from the absorbent-member support 240 beyond the main portion and has a contoured shape. In some embodiments, as shown, the base 210 may define a first base cavity that forms a portion of the overall first cavity 222 of the contact lens package 200, and a second base cavity that forms a portion of the overall second cavity 224 of the contact lens package 200. In some embodiments, as shown, a barrier 226 of the base 210 may be disposed between the first cavity 222 and the second cavity 224, and the barrier 226 may define an opening 228 that extends therethrough from the first cavity 222 to the second cavity 224. As discussed above, the base 210 may be formed of any suitable material. In certain embodiments, the base 210 may be substantially rigid. In other embodiments, the base 210 may be flexible.

The lens support 230 may at least partially define the first cavity 222 and may support the contact lens 260 in a desired position and orientation within the first cavity 222.

As shown, the lens support 230 may include an internal surface 232 (which also may be referred to as a "support surface" in certain embodiments) that engages and supports the contact lens 260 within the first cavity 222. In particular, the internal surface 232 may engage the concave surface of the contact lens 260. In some embodiments, the internal surface 232 may be a convex surface, although other shapes of the internal surface 232 may be used in other embodiments. As shown, the lens support 230 may be formed as a dome extending upward from the absorbent-member support 240, and the internal surface 232 may be a convex outer surface of the dome. As shown, the lens support 230 may include an external surface 234 disposed opposite the internal surface 232 and defining an external portion of the contact lens package 200. In some embodiments, the external surface 234 may be a convex surface, with the convex shape thereof facilitating nesting of multiple contact lens packages 200 disposed adjacent one another, such as in a stack, although other shapes of the external surface 234 may be used in other embodiments. The lens support 230 may be formed of any suitable material. In some embodiments, the lens support 230 may be substantially rigid.

The absorbent-member support 240 may at least partially define the second cavity 224 and may support the absorbent member 280 in a desired position and orientation within the second cavity 224. As shown, the absorbent-member support 240 may be recessed relative to the main planar portion of the base 210 and may support the absorbent member 280 between the base 210 and the lid 250. In some embodiments, as shown, the absorbent-member support 240 may be integrally formed with a remainder of the base 210.

As discussed above, the lid 250 may be formed of any suitable material. In certain embodiments, as shown, the lid 250 may be flexible.

The gate 252 may be connected to the lid 150 and configured for moving therewith when the contact lens package 200 is transitioned from the unopened state to an opened state for removal of the contact lens 260. As shown, the gate 252 may be configured for blocking the opening 228 of the barrier 226 when the contact lens package 200 is in the unopened state. In particular, the gate 252 may be configured for filling the opening 228 of the barrier 226 and sealing against adjacent surfaces of the base 210, including the barrier 226 thereof, when the contact lens package 200 is in the unopened state. When the contact lens package 100 is transitioned from the unopened state to the opened state, the gate 252 may move along with the lid 250 and out of the opening 228 such that the first cavity 222 and the second cavity 224 are in fluid communication with one another via the opening 228, thereby allowing the packaging solution 270 to flow from the first cavity 222 into the second cavity 224. The gate 252 may be formed of any suitable material.

The absorbent member 280 may be configured for absorbing at least a portion of the packaging solution 270 when the contact lens package 200 is transitioned from the unopened state to the opened state such that the first cavity 222 and the second cavity 224 are in fluid communication with one another. In some embodiments, the absorbent member 280 may be configured for absorbing a majority of the packaging solution 270 when the contact lens package 200 is transitioned from the unopened state to an opened state. In some embodiments, the absorbent member 280 may be compressible and configured for transitioning between a compressed state and an expanded state. In some embodiments, the absorbent member 280 may be biased toward the expanded state. In some embodiments, the absorbent member 280 may be in the expanded state when the contact lens package 200 is in the unopened state. In some embodiments, the absorbent member 280 may be in the compressed state when the contact lens package 200 is in the unopened state, and the absorbent member 280 may transition from the compressed state to the expanded state when the contact lens package 200 is transitioned from the unopened state to the opened state. In this manner, when the contact lens package 200 is in the unopened state, the absorbent member 280 may be compressed between the base 210 and the lid 250 and maintained in the compressed state, and when the contact lens package 200 is transitioned from the unopened state to an opened state, the absorbent member 280 may automatically transition from the compressed state to the expanded state. As discussed above, such transitioning of the absorbent member 280 from the compressed state to the expanded state may allow the absorbent member 280 to quickly absorb the packaging solution 270, thereby further facilitating drainage of the packaging solution 270 away from the contact lens 260. In some embodiments, the absorbent member 280 may be formed of or may include a sponge. In some embodiments, the absorbent member 280 may be formed of or may include a foam. In some embodiments, the absorbent member 280 may be formed of or may include a superabsorbent polymer. Various other suitable configurations and materials may be used for the absorbent member 280.

FIGS. 2C and 2D illustrate an example method of opening the contact lens package 200 in accordance with embodiments of the present disclosure. As noted above, the contact lens package 200 may be provided and stored in the unopened state, as shown in FIGS. 2A and 2C, until a user desires to open the package 200. With the contact lens package 200 in the unopened state, the user may hold the base 210 and grasp an end region of the lid 250, such as the end region of the lid 250 that is not directly connected to the base 210, as shown in FIG. 2C. The user may at least partially remove the lid 250 from the base 210 by pulling the end region of the lid 250 away from the base 210. In this manner, at least a portion of the seal between the lid 250 and the base 210 may be broken. As shown in FIG. 2D, the lid 250 may be removed from the base 210 such that the contact lens 260, the lens support 230, and at least a portion of the absorbent member 280 are no longer covered by the lid 250. In some embodiments, as shown, the entirety of the absorbent member 280 may be exposed. In some embodiments, the lid 250 may be entirely removed from the base 210. As discussed above, the lid 250 may be at least partially removed from the base 210 such that the first cavity 222 and the second cavity 224 are in fluid communication with one another, thereby allowing at least a portion of the packaging solution 270 to flow from the first cavity 222 into the second cavity 224 and be absorbed by the absorbent member 280 and drained away from the contact lens 260. As shown, the gate 252 may move along with the lid 250 as the lid 250 is at least partially removed from the base 210, such that the gate 252 is removed from the opening 228 of the barrier 226. In this manner, as the gate 252 is removed from the opening 228, the first cavity 222 and the second cavity 224 may be in fluid communication with one another via the opening 228, allowing the packaging solution 270 to flow therethrough. After at least partially removing the lid 250 from the base 210, as shown in FIG. 2D, the user may engage the contact lens 260 while the contact lens 260 is exposed and supported by the lens support 230. According to the illustrated embodiment in which the lens support 230 supports the concave surface of the contact lens 260, the user may engage the convex surface of the contact lens 260 and remove the contact lens 260 from the lens support 230. As discussed above, by allowing at least a portion of the packaging solution 270 to drain away from the contact lens 260 and be absorbed and contained by the absorbent member 280, the user may be able to easily engage and retain the contact lens 260 with the user's finger. In this manner, the contact lens 260 may be conveniently removed from the lens support 230 and held on the user's finger in the desired concave-side-up orientation, ready for positioning on the user's eye. Referring now to the drawings, FIGS. 3A-3D illustrate an example contact lens package 300 in accordance with embodiments of the present disclosure. As described, the contact lens package 300 may include a base 310, a lid 350, a contact lens 360, packaging solution 370, and an absorbent member 380. The contact lens package 300 may have an unopened state, as shown in FIGS. 3A and 3C, and an opened state, as shown in FIG. 3D. When the contact lens package 300 is in the unopened state, the contact lens 360 and the packaging solution 370 may be housed within a first cavity 322 formed between the base 310 and the lid 350, and the absorbent member 380 may be housed within a second cavity 324 formed between the base 310 and the lid 350. As shown, the first cavity 322 and the second cavity 324 may be disposed in a concentric manner, with the second cavity 324 surrounding the first cavity 322. As described below, the first cavity 322 and the second cavity 324 may be in fluid isolation from one another when the contact lens package 300 is in the unopened state, which may cause the packaging solution 370 to be disposed about and in contact with the contact lens 360 for maintaining hydration of the lens 360. In this manner, when the contact lens package 300 is in the unopened state, the packaging solution 370 may be contained within the first cavity 322, while the second cavity 324 and the absorbent member 380 contained therein may be devoid of any of the packaging solution 370. When desired, a user may open the contact lens package 300 by at least partially removing the lid 350 from the base 310 to allow access to the contact lens 360. Such opening of the contact lens package 300 may cause the first cavity 322 and the second cavity 324 to be in fluid communication with one another, allowing the packaging solution 370 to flow from the first cavity 322 into the second cavity 324 such that the absorbent member 380 absorbs a significant amount of the packaging solution 370, effectively draining the packaging solution 370 away from the contact lens 360. In this manner, such drainage of the packaging solution 370 away from the contact lens 360 may allow a user to remove the contact lens 360 more easily from the contact lens package 300. The at least partial removal of the lid 350 from the base 310 may expose the contact lens 360, allowing the user to engage and remove the contact lens 350 with the user's finger. As shown, a lens support 330 of the base 310 may maintain a position and orientation of the contact lens 360 within the first cavity 322 when the contact lens package 300 is in the unopened state. As shown in FIG. 3C, the contact lens 360 may be housed within the first cavity 322 and supported by the lens support 330 such that a convex surface of the contact lens 160 faces the lid 350 when the contact lens package 300 is in the unopened state. In this manner, when the contact lens package 300 is opened, the user may engage the convex surface for removal of the contact lens 360 and subsequent placement of the contact lens 360 on the user's eye, enabling a streamlined user experience and avoiding the drawbacks of certain existing contact lens packages.
