[Embodiment 1]
Hereinafter, one embodiment of the present disclosure will be described in detail. Unless otherwise specified in the present specification, "A to B" representing a numerical range means "A or more and B or less".

(Outline of contact lens 1)
The contact lens 1 irradiates the eyes of the wearing user with light of a predetermined wavelength band (second wavelength band), and causes the light of the predetermined wavelength band to be incident on the retina from the pupil P of the user. As a result, the contact lens 1 can bring about a non-visual effect on the mind and body of the wearing user.

(Outline of contact lens 1)
First, the schematic configuration of the contact lens 1 will be described with reference to FIG. FIG. 1 is a front view showing a user wearing the contact lens 1 according to the embodiment of the present disclosure. In FIG. 1, one eye of a user wearing a contact lens 1 is shown by a broken line.

As shown in FIG. 1, the contact lens 1 is a lens that can be worn on the user's eyeball. The contact lens 1 has a disk shape having a convex curved surface whose central portion protrudes from the peripheral portion.

The contact lens 1 may be worn on either the left eye or the right eye of the user, or may be worn on both the left and right eyes of the user. Hereinafter, when simply referring to one contact lens, it is referred to as "contact lens 1", and when referring to a pair of contact lenses 1 for both left and right eyes collectively, it is referred to as "contact lens set 2".

The contact lens 1 has a light emitting unit 10 that emits light in a second wavelength band different from the first wavelength band in response to receiving light in the first wavelength band. Further, the contact lens 1 may have a central region 12 and a peripheral region 17 surrounding the central region 12. Here, the central region 12 is a region corresponding to the pupil P of the user's eye. The central region 12 is located in front of the pupil P of the user's eye when the user wears the contact lens 1. On the other hand, the peripheral region 17 is a region adjacent to the edge of the central region 12 and surrounding the central region 12. As an example, the peripheral region 17 may be a region including a region corresponding to the iris I when the user wears the contact lens 1.

The central region 12 may include at least a part of the light emitting unit 10. For example, the light emitting unit 10 may be arranged in a part of the central region 12 or may be arranged in the whole in the central region 12. FIG. 1 shows a case where the light emitting unit 10 is arranged in the central portion of the central region 12. The light emitting unit 10 is not limited to this, and may be arranged in the central region 12 and the peripheral region 17.

According to one aspect of the present disclosure, it is possible to realize a contact lens capable of irradiating a user's eye with light in a predetermined wavelength band to bring about a non-visual effect on the user's mind and body. ..

<Light emitting unit 10>
Next, the light emitting unit 10 will be described. The light emitting unit 10 can irradiate the eyes of a user wearing the contact lens 1 on the eyeball with light in the second wavelength band. Since the light emitting unit 10 is arranged in the central region 12, the light in the second wavelength band emitted from the light emitting unit 10 reaches the retina from the pupil P of the user.

The light emitting unit 10 only needs to be able to irradiate the user's eye with light in the second wavelength band at a predetermined intensity (for example, the illuminance on the retina is 4 to 100 Lux), and the number of light emitting units 10 May be arbitrary. When the predetermined intensity is 4 to 100 Lux, it is possible to continuously relieve physical pain such as pain felt by the subject without causing the subject to feel glare. For example, as shown in FIG. 1, in the contact lens 1, one light emitting unit 10 may be arranged or a plurality of light emitting units 10 may be arranged. Further, the shape and size of the light emitting unit 10 may be arbitrary.

The light emitting unit 10 may contain a fluorescent dye that emits fluorescence (light in the second wavelength band) in response to receiving the excitation light (light in the first wavelength band). Here, the excitation light is light in the first wavelength band capable of changing the molecule of the fluorescent dye from the ground state to the excited state. The light emitting unit 10 may contain a fluorescent dye that emits fluorescence for a predetermined period after receiving the excitation light. In one example, the fluorescent dye applied to the light emitting unit 10 may be a fluorescent dye called a phosphorescent material. The phosphorescent material has a property of continuously emitting excitation light, which is light in the first wavelength band capable of changing the fluorescent dye molecule into an excited state, for a predetermined time (for example, 3 to 4 hours) after receiving the light. It is a fluorescent dye.

As the phosphorescent material, a known phosphorescent material may be used, but a strontium aluminate-based phosphorescent material that does not contain harmful substances such as radioactive substances may be used. For example, strontium aluminate (SrAl ₂ O ₄ , Sr ₄ Al ₁₄ O ₂₅ ) activated with rare earth elements such as europium (Eu) and dysprosium (Dy) can be mentioned. The phosphorescent material may be used alone or in combination of two or more. Further, the light-storing material may be a pigment having excellent water resistance.

The light emitting unit 10 is not limited to the fluorescent dye, and may contain, for example, an organic compound that emits phosphorescent light (light in the second wavelength band) for a predetermined period after receiving the excitation light (light in the first wavelength band). good.

[Wavelength band of light emitted by the light emitting unit 10]
The wavelength band of light emitted by the light emitting unit 10 may be any wavelength band of light that is expected to have an effect of improving the physical and mental condition of the user by irradiating the eyes of the user.

By irradiating the user's eyes with green light, it is possible to continuously relieve physical pain such as pain felt by the user after irradiation. The wavelength band of light emission may be the wavelength band of green light. In this case, the wavelength band of light emission is, for example, 450 to 600 nm, and may be 500 to 550 nm. The emission may be green light having a peak top of 525 nm.

By irradiating the user's eyes with purple light, it is possible to reduce the risk of deterioration of the user's visual acuity and reduce the rate of myopia progression. In this case, the wavelength band of light emission may be the wavelength band of purple light. In this case, the wavelength band of light emission may be, for example, 350 to 410 nm.

Further, by irradiating the user's eyes with blue light, the symptom of jet lag of the user can be alleviated. In this case, the wavelength band of light emission may be the wavelength band of blue light.

(Structure of contact lens 1)
Next, the configuration of the contact lens 1 will be described with reference to FIG. FIG. 2 is an exploded perspective view showing a schematic configuration of the contact lens 1. Hereinafter, a case where the light emitting unit 10 contains a fluorescent dye that emits fluorescence in the second wavelength band in response to receiving the excitation light in the first wavelength band will be described as an example.

The contact lens 1 may be provided with a protective layer. As shown in FIG. 2, in one example, the contact lens 1 includes a first protective layer 11 having an eyepiece surface K (that is, a rear curved surface) and a first inner surface L of the contact lens 1, a second inner surface M, and a second inner surface M. It has a second protective layer 16 having an objective surface N (that is, a front curved surface) and an intermediate layer 15 having a light emitting portion 10. Here, the eyepiece surface K is intended to be the surface of the contact lens 1 on the side in contact with the eye, and the objective surface N is intended to be the surface of the contact lens 1 on the side facing the eyepiece surface K.

The first protective layer 11 is capable of transmitting the fluorescence from the light emitting unit 10. That is, at least a part of the light emitting portion 10 is covered with a protective layer that transmits fluorescence. At least a part of the fluorescence emitted from the light emitting unit 10 enters from the first inner side surface L, travels in the eyepiece K direction, passes through the user's pupil P, and reaches the retina. Further, the first protective layer 11 may be capable of transmitting visible light.

The second protective layer 16 may be capable of transmitting the fluorescence from the light emitting unit 10. That is, the light emitting unit 10 may be covered with a protective layer that transmits fluorescence. At least a part of the fluorescence emitted from the light emitting unit 10 enters from the second inner side surface M and travels in the direction of the objective surface N to reach the user's eyelids. Further, the second protective layer 16 may be capable of transmitting visible light.

In some cases, the second protective layer 16 may be able to shield or reduce light from the outside. When the contact lens 1 having such a second protective layer 16 irradiates the user's eye with green fluorescence from the light emitting unit 10, the contact lens 1 reaches the user's eye and has a wavelength band different from that of the fluorescence. The illuminance can be reduced. Therefore, the contact lens 1 can sustain the pain-relieving effect obtained by the green fluorescence.

The light emitting portion 10 is covered with the first protective layer 11 and the second protective layer 16. As a result, it is possible to prevent the fluorescent dye applied to the light emitting unit 10 from directly touching the eyes and eyelids of the user wearing the contact lens 1 and affecting the user's body.

The first protective layer 11 and the second protective layer 16 may be composed of, for example, a silicone hydrogel, a non-silicone hydrogel, or the like.

(Manufacturing method of contact lens 1)
As a method for manufacturing the contact lens 1, a known method may be used. For example, a race cut method (cutting and polishing method), a cast molding method (molding method), a spin casting method (centrifugal molding method), and these methods can be used. A combined method may be used.

Examples of the raw material of the contact lens 1 include silicone hydrogel and non-silicone hydrogel. From the viewpoint of oxygen permeability, a silicone hydrogel may be used as a raw material for the contact lens 1.

The contact lens 1 having the configuration shown in FIG. 2 may be manufactured by using, for example, a cast mold method and a sandwich method. Specifically, (1) First, the raw material to be the second protective layer 16 is poured into a mold for the objective surface N side. (2) Subsequently, an intermediate layer 15 having a light emitting portion 10 containing a fluorescent dye is installed on the second protective layer 16. (3) Next, the raw material to be the first protective layer 11 is further poured from above the intermediate layer 15, and the mold for the eyepiece K side is covered from above.

[Embodiment 2]
Other embodiments of the present disclosure will be described below. For convenience of explanation, the members having the same functions as those described in the above-described embodiment are designated by the same reference numerals, and the description thereof will not be repeated.

The fluorescence emitted from the light emitting unit 10 includes light in the direction emitted from the eyepiece surface K and light in the direction emitted from the objective surface N. The contact lens 1a according to the present embodiment is a contact lens in that it has a reflecting portion 13 for changing the light emitted from the objective surface N to the light in the direction of the user's eyes. It is different from 1.

Here, the configuration of the contact lens 1a will be described with reference to FIG. FIG. 3 is an exploded perspective view showing a schematic configuration of a contact lens 1a having a reflecting portion 13.

<Reflector 13>
The reflecting unit 13 reflects the light in the direction emitted from the objective surface N in the direction emitted from the eyepiece surface K. The reflective portion 13 may be provided on the second protective layer 16. The reflecting unit 13 may reflect the light of the light emitting unit 10, and may be made of, for example, a specular reflection material, a diffuse reflection material, a retroreflection material, or the like.

As shown in FIG. 3, the reflecting portion 13 may be arranged on the second inner side surface M of the second protective layer 16 or may be arranged on the objective surface N of the second protective layer 16. .. When the reflective portion 13 is arranged on the second inner side surface M or the objective surface N of the second protective layer 16, for example, the reflective portion 13 is subjected to a coating treatment such as mirror coating and aluminum vapor deposition on the second protective layer 16. Can be provided.

Further, the second protective layer 16 may be processed by prism processing or the like, and the second protective layer 16 itself may function as the reflecting portion 13.

Since the contact lens 1a has the reflecting unit 13, the fluorescence emitted from the light emitting unit 10 can be efficiently applied to the user's eyes. Further, the contact lens 1a can manufacture the light emitting unit 10 with a smaller amount of fluorescent dye than the contact lens 1. For example, when the price of a fluorescent dye such as a phosphorescent material is high, the contact lens 1a having the reflecting portion 13 can keep the manufacturing cost lower than that of the contact lens 1.

On the other hand, the reflective portion 13 may be provided on the entire second protective layer 16 or may be provided on a part of the second protective layer 16. Further, the reflecting unit 13 may reflect only a part of visible light.

For example, visible light such as blue light (eg, wavelength of 410-470 nm) or purple light (eg, wavelength of 350-410 nm), or ultraviolet light (eg, wavelength of less than 350 nm) can be used as excitation light. .. Light of these wavelengths may be used alone or in combination of two or more as the excitation light. When visible light is irradiated as the excitation light, the product life of the contact lens can be improved. Further, when purple light or ultraviolet rays are irradiated as the excitation light, germs adhering to the contact lens can be reduced.

FIG. 4 shows, but is not limited to, a contact lens case 40 capable of accommodating a pair of contact lenses 1 for both left and right eyes (that is, a contact lens set 2). For example, one contact lens 1, 1a may be accommodated in each contact lens case 40, or three or more contact lenses 1, 1a may be accommodated together.

The contact lens case 40 includes an accommodating portion 21 capable of accommodating contact lenses 1 and 1a, a light source 23 for irradiating the contact lenses 1 and 1a in the accommodating portion 21 with excitation light, and a power supply unit for supplying electric power to the light source 23. 25 and.

The contact lenses 1 and 1a are accommodated in the accommodating portion 21 through the opening 27. In FIG. 4, one contact lens 1, 1a is accommodated in each accommodating portion 21, but the present invention is not limited to this. For example, when one accommodating portion 21 is separated by a partition or the like, or when a part of the inner wall 24 of two or more recesses of the accommodating portion 21 is connected to each other, two pieces are formed in one accommodating portion 21. The above contact lenses may be accommodated.

In addition to the contact lenses 1 and 1a, the accommodating portion 21 may accommodate a chemical solution such as a preservative solution and a disinfectant solution for caring for the contact lenses 1 and 1a. The chemical solution is contained in the accommodating portion 21 through the opening 27. However, the chemical solution may contain a component that is not easily decomposed by the excitation light emitted from the light source 23 described later.

The number of accommodating portions 21 included in the contact lens case 40 is not particularly limited, but may be one or a plurality, for example. For example, if the number of accommodating portions 21 is two or more, at least a pair of contact lenses 1 for both left and right eyes (that is, a contact lens set 2) can be accommodated.

<Light source 23>
The light source 23 may be provided at an arbitrary position where the contact lenses 1 and 1a housed in the housing portion 21 can be irradiated with the excitation light. As an example, the light source 23 may be provided at the bottom of the accommodating portion 21 or may be provided on the inner surface of the accommodating portion 21. Alternatively, as shown in FIG. 4, the light source 23 may be provided on the lid portion 22, which will be described later. Further, when the contact lens case 40 includes the lid portion 22 described later, the light source 23 may be provided on the lid portion 22.

The light source 23 may include a light emitting element such as a light emitting diode (LED) and a semiconductor laser (LD). By using these light emitting elements, the light source 23 can efficiently excite the light emitting material of the light emitting unit 10. Alternatively, the light source 23 may include, in addition to the light emitting element, an optical filter (for example, a bandpass filter) that transmits only the excitation light among the light from the light emitting element.

<Power supply unit 25>
The power supply unit 25 supplies electric power to the light source 23. The power supply unit 25 may include a battery terminal that accepts any type of battery (for example, a primary battery, a secondary battery, a fuel cell, and the like). Alternatively, the power supply unit 25 may have a plug or the like that can be plugged into an outlet and may be configured to receive power from an external power source.

The contact lens case 40 may further include a lid portion 22, and the light source 23 may be provided on the lid portion 22. When the light source 23 is provided on the lid portion 22, power may be supplied from the power supply unit 25 to the light source 23 via, for example, a connection portion 26 connecting the lid portion 22 and the case body 20.

In FIG. 4, one light source 23 is provided at a position corresponding to each accommodating portion 21, but the light source 23 is not limited to this. For example, a plurality of light sources 23 may be provided at positions corresponding to each accommodating portion 21. Alternatively, one light source 23 may be provided at a position where the excitation light can be irradiated toward the plurality of accommodating portions 21.

<Cover 22>
The lid portion 22 is a member that covers the recess of the accommodating portion 21. When the contact lens case 40 includes the lid portion 22, it is possible to prevent dust and the like from entering the accommodating portion 21. Further, the lid portion 22 can prevent the excitation light radiated from the light source 23 to the contact lenses 1 and 1a from leaking to the outside of the contact lens case 40.

The lid portion 22 and the contact lens case 40 may be made of resin or metal. It may be possible to prevent the excitation light having a relatively high energy from leaking to the outside from the contact lens case 40. Therefore, the lid portion 22 and the case body 20 may be configured so as not to transmit light having a short wavelength (for example, ultraviolet rays).

In one example, the light source 23 is configured to irradiate the contact lenses 1 and 1a with excitation light from the upper part of the accommodating portion 21 when the lid portion 22 is closed, and to turn off the light when the lid portion 22 is opened. May be good. For example, as a trigger for the light source 23 to start irradiating the excitation light, a detection signal for detecting that the lid portion 22 is closed and the lid portion 22 and the case body 20 are locked may be used.

Alternatively, the lid portion 22 or the case body 20 may be provided with a button or a switch (not shown) for controlling ON / OFF of the light irradiation of the light source 23.

[Modification example]
FIG. 4 shows an example in which each contact lens case 40 includes a light source 23, but the present invention is not limited thereto. For example, the contact lens unit 100 includes a light source device (not shown) including a light source 23 capable of collectively irradiating a plurality of contact lens cases 40, which is separate from the contact lens case 40. You may.

In one example, the lid 22 and the case body 20 of the contact lens case 40 may be capable of transmitting the excitation light from the light source 23 of the light source device. Alternatively, the lid portion 22 may be provided with a window portion through which the excitation light from the light source 23 of the light source device can pass. If this configuration is adopted, the excitation light from the light source device can be applied to the contact lenses 1 and 1a housed in each of the plurality of contact lens cases 40.

A user who uses a visual acuity correction contact lens removes the contact lenses 1 and 1a from the eye, and then wears the visual acuity correction contact lens. The contact lenses 1 and 1a housed in the contact lens case 40 are irradiated with the excitation light from the light source 23. The contact lenses 1 and 1a are held in the contact lens case 40 until the user next prepares to go to bed. During this period, the contact lenses 1, 1a receive sufficient excitation light.

At the time of t4, the user prepares to go to bed in the same manner as at the time of t1 above. The time point t5 indicates the disappearance of fluorescence of the contact lenses 1 and 1a as at the time point t2, and the time point t6 indicates that the user accommodated the contact lenses 1 and 1a in the contact lens case 40 as at the time point t3. In this way, by attaching the contact lenses 1 and 1a to the user before going to bed, the user can irradiate the user's eyes with fluorescence from the light emitting unit 10 while the user is sleeping. As described above, the contact lenses 1 and 1a can perform a treatment of irradiating the user's eyes with fluorescence in a predetermined wavelength band that has a non-visual effect on the mind and body even when the user is sleeping. do.

Contact lenses 1 and 1a may be replaced with new ones after each use in consideration of hygiene. Alternatively, the contact lenses 1, 1a may be used repeatedly by immersing the used contact lenses 1, 1a in a chemical solution such as a preservative solution and a disinfectant solution.
