Background
At present, in our daily life, besides sunlight and ultraviolet rays, irregular diffuse reflection light, commonly called glare, is generated when light passes through a rugged road surface, a water surface and the like. The occurrence of glare can cause discomfort of human eyes, generate fatigue and influence the definition of visual objects; the existing common dyeing mirror can only reduce the intensity of light and cannot effectively remove the light reflection of a bright surface and the glare of all directions. Short-wave blue light is light with relatively high energy at wavelengths between 400nm and 480 nm. Blue light in the wavelength can increase the amount of toxins in the macular region of the eye, seriously threatens the health of the eyeground of people, and induces blindness eye diseases. The influence of glare and blue light is eliminated, and people can be potentially harmed by ultraviolet rays, radiation and the like in daily life. There is a need for an optical lens that can resist these hazards.
Blue light is a visible light with a wavelength of 400-500 nm. The wavelength is 415-455 nm, which is called harmful blue light. Since the wavelength of harmful blue light is short, the focus point does not fall on the center of the retina. The eyeballs are easy to be in a tense state for a long time, so that asthenopia is caused, and the problems that the degree is deepened, the attention cannot be concentrated and the like are easily caused by the long-term asthenopia. The light harmful to the eyes includes not only blue light but also ultraviolet light, blue light, violet light, harmful electromagnetic radiation, and the like, and generally, the shorter the wavelength is, the more energy is, the more damage is to the eyes. The ultraviolet ray has great damage to the skin and the eyes, especially the eyes are easy to cause keratitis when being irradiated by the ultraviolet ray for a long time, and the eyes are easy to cause cataract and maculopathy when being irradiated by the ultraviolet ray for a long time for middle-aged and old people. Radiation eye damage can be caused by the impact of various radiation rays in the electromagnetic spectrum on the eye, such as microwaves, infrared rays, visible light, ultraviolet rays, X rays, R rays, and the like.
At present, on the market, the lens has single or simple function, cannot meet the optimal eye protection requirement, has poor optical condition and unstable lens quality.
Through the above analysis, the problems and defects of the prior art are as follows:
the existing functional lens has single or simple function, poor optical condition and unstable lens quality, and cannot meet the actual requirements of the market.
The difficulty in solving the above problems and defects is:
the existing functional lens has single or simple function, poor optical condition and unstable lens quality, needs to develop a new lens function process, perfects the functional coverage of the lens and has more reliable and stable quality.
The significance of solving the problems and the defects is as follows:
the new process adopts a film coating technology, and the formula of the lens material is prepared according to harmful light, so that the harm of the harmful light is reduced.
