Description

lens

This creation is about a lens, especially a lens suitable for outdoor activities.

Sunglasses are a common household item to block the glare of ultraviolet light, so that when people are engaged in outdoor sports and driving activities, the eyes can be protected from glare. Common features of sunglasses are blocking UV rays, reducing light intensity and polarizing.

As shown in Fig. 1, the sunglasses on the market have a transmittance of only about 20% in the range of wavelengths of 400 nm to 650 nm. After wearing such glasses, the eye muscles need to adjust the pupil to adapt to the weak light environment due to insufficient light transmittance. Therefore, the eyes are prone to fatigue after wearing for a period of time.

In addition, studies have shown that short-wavelength (about 415 to 450 nm) blue light can cause cataracts, macular lesions and damage to retinal cells. The long wavelength (about 450 nm to 500 nm) blue light is a beneficial part of the human body. Therefore, not all wavelengths of blue light can damage the eyes, and existing sunglasses maintain low transmittance regardless of the wavelength, and there is a need for improvement.

The creators of this creation have painstakingly studied, thought and designed a lens to solve the problems of the prior art.

The technical means for solving the problems of the prior art is to provide a lens having a light incident surface and a light exiting surface, and a dye doping layer between the light incident surface and the light emitting surface, the dye The doped layer is doped with a dye, so that the lens gradually increases the transmittance for light having a wavelength of 450 nm or more and changes the color depth with the intensity of the ultraviolet light.

In one embodiment of the present disclosure, a lens is provided wherein the material of the lens contains a photochromic oligomer.

In one embodiment of the present disclosure, a lens is provided wherein the material of the lens contains polyurethane.

In one embodiment of the present disclosure, a lens is provided wherein the lens is gray.

In one embodiment of the present disclosure, a lens is provided wherein the lens exhibits a tin color.

Through the technical means of this creation, a lens is proposed to gradually increase the transmittance of light having a wavelength of 450 nm or more to reduce the fatigue caused by eye adjustment force and improve the clarity of vision. Moreover, in the range of short-wavelength blue light, 70-80% of short-wavelength blue light is filtered to protect the retina from damage and to block visual interference caused by scattering of short-wavelength blue light. In addition, the lens of this creation can isolate more than 99% of ultraviolet rays, protect the crystals from disease, improve the ability to clear, and change the color depth with the intensity of ultraviolet light to help the eyes adapt to the light intensity. In addition, the lens of the present invention has the effect of brightening and increasing the color contrast in a dark environment such as a tunnel, which can increase driving safety. Due to the above advantages, the lens of the present invention is suitable for the user to wear for outdoor activities or driving. special Yes, compared with the existing color-changing lens, a color-changing film or a polarizer is added to the lens, and the present invention directly dyes the lens, discolors with ultraviolet intensity, and eliminates glare by using the dye doped with the dye-doped layer. Belongs to an innovative creation.

In summary, the case is not only innovative in terms of space type, but also can enhance the above-mentioned multiple functions compared with the conventional articles. It should fully comply with the statutory new patent requirements for industrial utilization, novelty and progress, and apply in accordance with the law. I urge you to approve this new type of patent application to encourage creation and to be sensible.
