Description

Filters for glasses

This new model relates to a filter patch, especially a patch with one or more filter layers, which can be instantly cut according to the size and shape of the spectacle lens, and attached to the lens for use, so that the lens can filter light The function of those.

With the rapid development of sound, light, audio and video media, coupled with the popularization of portable mobile phones, people’s eyesight is also prone to fatigue and degenerate in addition to convenient access to information. Under the stimulation of sound and light equipment, the proportion of children’s myopia has increased year by year. high. In addition to acousto-optic equipment, sunlight and even light of different wavelengths emitted by light-emitting diodes (LEDs) can also affect people's vision, causing the number of people wearing glasses to increase.

The rapid development of optical technology has prompted spectacle lenses to have multiple functions, including corrective spectacle lenses for myopia, hyperopia, and presbyopia or bifocal spectacle lenses suitable for both near and far. However, spectacle lenses with multiple functions or special effects are often expensive, which is beyond the reach of ordinary income earners. In order to meet the needs of people who cannot afford high-priced spectacle lenses and have to achieve filtering effects, the shop has already developed dark-colored plastic spectacle lenses that are equivalent to spectacle lenses.

As shown in Figure 1, the conventional dark-colored plastic eyeglass secondary lens 10 is clamped on the frame 40 of the glasses 30 through a clamp 20. Since the fixture 20 has the function of flipping the plastic eyeglass secondary lens on it, Therefore, according to the needs of the user, when the light needs to be blocked, the dark-colored plastic spectacle lens 10 can be vertically hung in front of the spectacle lens 50, so that part of the light can be blocked, reducing the penetration of the spectacle lens and entering the eyes When there is no need to block the light, lift the bottom edge of the dark-colored plastic eyeglass secondary lens 10 so that the plastic eyeglass secondary lens 10 lies flat on top of the eyeglass lens 50.

However, through the flip-up dark-colored plastic eyeglass secondary lens 10, although the effect of blocking light can be achieved, the user has only two choices of blocking light or not blocking light, and the dark-colored plastic eyeglass secondary lens 10 is clamped When used on the frame 40, it is often easy to fall off, and it will also increase the obstacle of the visual angle of the eye. However, the conventional spectacle lenses cannot meet the different needs of people at different times.

In view of this, the creator, based on his experience in manufacturing various optical glasses products and accumulated technology, has researched and improved methods for the deficiencies of the aforementioned dark-colored plastic eyeglasses. After continuous research and experimental improvements, he finally developed the creation. The filter patch of the new type of glasses is produced.

Therefore, the purpose of the present invention is to provide a filter patch for spectacles. The filter patch is formed by elastic soft rubber materials such as latex, which can be selected by people according to their own needs and cut immediately according to the size and shape of the spectacle lens. And put it on the spectacle lens in time for use.

According to the new type of optical filter patch for glasses, it has one or more than one filter layer. After molding, the optical filter patch is combined with a release paper to make it easy to carry or transport. It also has a protective patch Not hurt, this is the second purpose of the new model.

According to the optical filter patch for glasses of the present invention, the filter layer is formed on the surface of the gum base of the patch by a coating method, or dyes of different colors are mixed into the gum base when the patch is formed, and then attached This is another purpose of the new model.

According to the filter patch of the glasses of the present invention, it can be made according to the wavelength of light, which can block light of specific wavelength or even intensity, so as to achieve the most appropriate needs of people, which is another purpose of the new type.

According to the spectacles filter patch of the present invention, since the thickness of the patch can be very thin, its surface is not smooth, when it is attached to the spectacle lens, there is no gap between the two, and it can be completely attached to the spectacle lens It is almost integrated, so it will not fall off or affect the viewing angle, which is another purpose of this new model.

In order to facilitate your reviewer to have a further understanding and understanding of the purpose, shape, features and effects of the structure of the new model, the following examples are provided in conjunction with the diagrams to explain the structure of the new model in detail:
