Description

Lens structure with optical features

This work relates to the technical field of eyeglass lenses, and more particularly to a lens structure containing optical lenses as its creative application.

Note that glasses were initially developed to correct various vision problems, such as myopia, hyperopia, astigmatism, presbyopia, etc. With the development of technology and industry, glasses are no longer just a tool for correcting vision. Glasses have developed more functions, such as glasses products suitable for different environments, occasions, or sports, such as safety goggles, sunglasses, windproof goggles, snow goggles, etc.

However, we know that existing functional glasses such as goggles, sunglasses, windproof goggles, or snow goggles do not have vision-correcting functions. Therefore, when people with myopia, hyperopia, or presbyopia wear functional glasses, they must remove the optical glasses with vision-correcting functions, resulting in blurred vision. This poses a danger not only to the individual but also to the safety of others when driving or engaging in activities. Therefore, non-prescription functional glasses are no longer sufficient to meet the needs of modern people.

As a result, the industry has developed many additional frames or lenses, which are attached to the inside or outside of a main frame or lens using magnetic, clip, or hinge methods, such as M645386, M647958, M544012, M563563, M559415, M558915, etc. However, these types of glasses require an extra lens, which changes the focal length of the glasses, increasing costs and making them less than ideal in terms of usability. Therefore, how to enable users to correct their vision when wearing any different functional glasses is one of the topics that this creator has focused on researching.

The reason is that, based on years of rich design, development and practical production experience in the relevant industry, the creator has actively researched and developed a new lens structure with optical features, in order to achieve better practical value.

The main purpose of this invention is to provide a lens structure with optical features, specifically an optical lens that can be set on the end face of the lens to correct vision, and whose outer area can be cut to match various frame designs.

The main purpose and function of this optically-featured lens structure are achieved through the following specific technical means:

It mainly includes a lens substrate, on one end face of which at least one optical feature is integrally formed, which is an optical lens for correcting vision. The lens substrate has a frame edge that can be cut according to the shape of the lens frame. In this way, the range of applications of the lens is increased and subsequent processing is saved.

This invention contains a preferred embodiment of a lens structure with optical features, wherein the lens rim can be correspondingly combined with a full-frame, semi-frame, or rimless lens temple.

This invention contains a preferred embodiment of a lens structure with optical features, wherein the lens substrate is manufactured by molding, and the curvature of the optical lens is formed by a replaceable mold core.

This invention contains a preferred embodiment of a lens structure with optical features, wherein the lens substrate is a plano lens or a tinted lens.

This invention contains a preferred embodiment of a lens structure with optical features, wherein the optical lens is a myopia lens, hyperopia lens, astigmatism lens, or presbyopia lens.

To more fully and clearly reveal the technical content, creative purpose, and effects achieved in this work, a detailed explanation is provided below, along with the accompanying drawings and figure numbers:

First, please refer to the first and second figures, which are schematic diagrams of the three-dimensional appearance of the lens structure containing optical features in this creation. It mainly includes a lens substrate (1), which has inner and outer end faces (11) and (12) and a surrounding frame edge (13). At least one optical feature (14) is integrally formed on the inner end face (11) of the lens substrate (1). The optical feature (14) is an optical lens (14a) for correcting vision. The frame edge (13) of the lens substrate (1) can be processed to form a lens rim (13a).

Please refer to Figures 1-4. In actual production, the lens substrate (1) is manufactured using molding. Depending on the type of eyeglasses, the lens substrate (1) can be made into a plano lens or a tinted lens. Further molding is mainly done by shaping the lens substrate (1) with a mold, and at least one optical feature (14) is integrally formed on the inner end face (11) of the lens substrate (1). (14) is an optical lens (14a) for correcting vision. The optical lens (14a) refers to a lens that can be used as a lens for correcting myopia, hyperopia, astigmatism or presbyopia. The curvature of the optical lens is made by setting an interchangeable mold core (2) in the mold. The mold core (2) with different curvatures is selected according to the degree of correction [the curvature of the mold core (2) is different for different degrees] to mold [as shown in the third figure].

Once the lens is completed, it can be a single lens type [single optical feature (14)] as shown in Figure 1, or an integrated lens type [two optical features (14)] as shown in Figure 2. The frame edge (13) of the lens substrate (1) is an unprocessed periphery. Further refer to Figures 5 to 8. The lens substrate (1) can be processed to form a lens edge (13a) according to the lens frame type, so that the lens edge (13a) can be combined with a full-frame lens frame (3) [as shown in Figure 5], a half-frame lens frame (4) [as shown in Figures 6 and 7] or a frameless temple (5) [as shown in Figure 8].

The foregoing embodiments or diagrams are not intended to limit the structural form of this work. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this work.

Based on the above description and implementation of this invention, it can be seen that, compared with existing technologies, this invention mainly has the following advantages:

1. This invention features a lens structure with optical characteristics. By integrally forming at least one optical lens on the inner end face of the lens substrate, it effectively increases the range of applications for the lens and saves manufacturing steps and subsequent processing.

2. This creation features a lens structure with optical characteristics. The curvature of the integrally projected optical lens is achieved using an interchangeable mold core. Different curvature mold cores are used for different degrees, or it can be machined using CNC, which can effectively adapt to changes in the degree of correction.

3. This invention features a lens structure with optical characteristics. The lens substrate is integrally projected as an optical lens that can correct vision. It can be positioned within the user's field of vision. The area of the lens substrate outside the optical lens is processed by methods such as cutting, trimming, or grinding to create a lens rim that can be matched with various frames, achieving a wide range of applications and convenient benefits.

In conclusion, this invention embodiment can indeed achieve the intended use effect, and the specific structure disclosed therein has not only never been seen in similar products, but has also not been disclosed before the application.
