Description

Eyeglass lens

The present invention relates to a spectacle lens, and more particularly to an anti-infrared and anti-ultraviolet spectacle lens.

In recent years, ultraviolet light has been proven to be harmful to the eyes. Exposure of the eyes to ultraviolet light for a long time is not only easy to degrade the eyes in advance, but also chronically damage the crystals, resulting in cataracts. However, infrared and glare can also hurt your eyes. In our daily environment, it is full of infrared rays, but because the eyes can't feel it, it ignores the chronic damage of infrared rays. Infrared rays can damage the lens of the eye, causing opacity of the lens, causing cataract or decreased vision. Glare is the glare of light, because the brightness in the field of view greatly exceeds the range that the eye can adapt to, causing annoyance, discomfort, visual fatigue or damage to the lens, resulting in impaired vision.

In the prior art, the ultraviolet rays of the sunglasses are used to filter the ultraviolet rays to prevent the ultraviolet rays from harming the eyes. However, sunglasses are only suitable for wearing outdoors when the sun is glaring, and it is not possible to filter ultraviolet rays with UV-resistant lenses in general environments. Later, a color-changing lens was developed to add a color-changing film layer on the outside of the UV-resistant lens. This color-changing film layer can increase the light transmittance when the environment is darkened, and can still be used for UV-resistant lens filtering in a dark environment. Ultraviolet light. However, this lens still does not filter infrared and glare damage to the eyes.

In view of the above, the lenses of the prior art have the disadvantage of not being able to filter infrared rays and glare but the eyes are damaged, and there is a need for improvement.

Therefore, the purpose of this creation is to provide an eyeglass lens that is resistant to infrared light and ultraviolet light and prevents glare.

Embodiments of the present creation will be described below based on Figs. 1 to 6 . This description is not intended to limit the implementation of the present invention, but is one of the embodiments of the present invention.

As shown in FIG. 1, a spectacle lens 100 according to an embodiment of the present invention includes: a lens body 1; and a resistive film layer 2 including a plurality of film portions 21, each of which is made of anti-infrared rays. The material, the ultraviolet-resistant material, and the semi-transparent material are formed, and the plurality of film portions 21 are evenly spaced apart from each other on the rear side surface of the lens body 1, and a plurality of light-transmitting narrow portions are formed between the plurality of film portions 21. The slit 22 is formed by the plurality of thin film portions 21 and the plurality of light transmissive slits 22 to form a dimming softening structure.

As shown in Figures 1 and 2, the lens is a spectacle lens made of plastic or glass to correct vision or protect the eye. In this embodiment, the lens body 1 is an anti-blue light-stained lens for absorbing and filtering blue light (blue light is the most powerful visible light, the wavelength is between 380-500 nm, the source of common blue light: LED, television, screen , smart phones, tablets, interior lights, lights, sunlight, etc.). In another embodiment of the present invention, the lens body 1 is a polarizing lens having a polarizing filter film 7 for absorbing the reflection of the filtering deflection. Of course, the present invention is not limited thereto. The lens body 1 can also be a general myopia lens or a far-sight lens, or a color-changing lens that changes light transmittance according to light intensity.

As shown in FIG. 1 and FIG. 2, specifically, in the present embodiment, the resistive film layer 2 is a semi-transmissive film having chromium oxide for reflecting and absorbing infrared rays and ultraviolet rays. As shown in FIG. 5, when the external strong light I1 is incident on the lens portion 21 and penetrates the lens body 1, the strong light I1 is partially reflected by the thin film portion 21 to reflect infrared rays and ultraviolet rays, and is reflected. The light I3 containing a high dose of infrared rays and ultraviolet rays is emitted, and the remaining portion passes through the thin film portion 21 and is absorbed by the thin film portion 21 to absorb a residual amount of infrared rays and ultraviolet rays to generate a very small amount of infrared light and ultraviolet filter light I2. When the external light I4 contains only a very small amount of infrared rays and ultraviolet rays, it is directly transmitted through the lens body 1 and the thin film portion 21 after being incident. If the external incident light I5 is incident on the lens body 1 and penetrates the light-transmitting slit 22, as shown in FIG. 6, the incident light I5 is subjected to the dimming softening structure of the plurality of light-transmissive slits. Reduce glare and glare. Moreover, the plurality of light-transmissive slits have the effect of pinhole glasses, which are used to relax the ciliary muscle to increase the clarity, and can increase the chance of restoring part of the vision, and is helpful for the initial cataract.

As shown in Figs. 1 and 3, in the present embodiment, the resistive film layer 2 is preferably a physical vapor deposition coating, and can be uniformly arranged with a fine interval therebetween. The plurality of thin film portions 21 are a plurality of hexagonal films of the same size and are arranged adjacent to each other to form a honeycomb shape. Of course, the present invention is not limited thereto, and other plural films of the same size may be arranged adjacent to each other. The hexagonal film has a longitudinal length L of 0.2 to 0.3 mm and a lateral width W of 0.14 to 0.18 mm. The width D of the light-transmitting slit 22 is 0.05 to 0.25 mm.

The anti-reflective protective film 5 and the impedance protective layer 3 are multilayer protective films. The multilayer protective film uses a plurality of transparent metal oxides (such as commonly used in the studio: green film, purple film, blue film) to reduce the reflected light of different wavelengths and increase the transmittance.

The impedance protection layer 3 is disposed on the rear side surface of the resistive film layer 2 and serves to protect the resistive film layer 2. The two nano protective films 41 and 42 are respectively attached to the front side surface of the lens body 1 and are attached between the rear side surface of the lens body 1 and the resistive film layer 2. The two nano protective films 41 and 42 are thin molecular coatings for reducing the friction coefficient, increasing wear resistance and smoothness, and preventing oil from being pulled, and the nano protective film 41 and 42 can be easily wiped off. Dirty.

As shown in FIG. 2 and FIG. 4, the two embodiments are two preferred embodiments. Of course, the present invention is not limited thereto. The lens 100 of the present invention may also include only one lens body 1 and A resistive film layer 2 or other film bodies are attached to the lens body 1 and the resistive film layer 2.

With the above configuration, the spectacle lens 100 of the present embodiment is reduced by filtering the infrared rays and ultraviolet rays incident on the lens body 1 and the light-transmitting slits 22 of the resistive film layer 2 by the thin film portion 21 of the resistive film layer 2. The glare and glare of light cause the light to pass through the resistive layer 2 and reach the eyes with a small amount of soft light of infrared rays and ultraviolet rays, thereby reducing the damage of the crystal lens, relaxing the ciliary muscles, reducing eye fatigue and protecting the eyes.

The above description and description are only illustrative of the preferred embodiments of the present invention, and those having ordinary skill in the art may make other modifications in accordance with the scope of the patent application as defined below and the above description, but such modifications are still It is the creative spirit of this creation and is within the scope of this creation.
