Anti-dazzle and anti-ultraviolet protective lens

Abstract

The invention discloses an anti-dazzle anti-ultraviolet protective lens which comprises a lens base body, the lens base body comprises a front substrate, a rear substrate and a nano composite film layer compounded between the front substrate and the rear substrate; the nano composite film layer is provided with an anti-dazzle film layer located in the center and a plurality of thin film layers located on at least one side of the anti-dazzle film layer; the plurality of thin film layers comprise a 1.5 refractive index film layer, a 1.67 refractive index film layer and an anti-ultraviolet film layer; the outer surface of the front substrate and the outer surface of the rear substrate are each provided with a semi-circle of radian groove in a surrounding mode, the radian grooves are corresponding to each other, and the radian grooves are used for installing silica gel clamping frames. The nano-composite film layer is arranged between the front substrate and the rear substrate, so that anti-dazzle and anti-ultraviolet effects are achieved; meanwhile, the silica gel clamping frames are clamped in the semi-circle radian grooves in an embedded mode, taking and using are convenient, and the trouble of falling and bumping is avoided.

Description

technical field [0001] The invention belongs to the technical field of lenses, and in particular relates to an anti-glare and anti-ultraviolet protective lens. Background technique [0002] Ultraviolet rays can cause damage to the eyes, and long-term exposure to ultraviolet rays can cause cataracts. Similarly, blue light is high-energy visible light with a wavelength of 400-500nm. The higher the blue light radiation component, the greater the damage to visual cells, which will blur the retinal image and cause visual fatigue. Under the action of ultraviolet light and blue light, vision will gradually decrease, and it is easy to cause premature cataract and spontaneous macular degeneration such as dry eyes, photophobia, and fatigue. When driving at night, if the oncoming vehicle uses high-power lights in violation of regulations, the driver will have a dazzling feeling, and it will be difficult for the vision to return to normal for a long period of time, which will easily ...

AI Technical Summary

Problems solved by technology

When driving at night, if the oncoming vehicle uses high-power lights in violation of regulations, the driver will have a dazzling feeling, and it will be difficult for the vision to return to normal for a long period of time, which will easily cause traffic accidents.

[0003] In order to solve the above problems, the optical lenses produced in the prior art are generally coated with various functional films on the outside of the lens base. If they are exposed to the air for a long time to oxidize, their functions will be lost, and they will be easily scratched and worn. Failure, in addition, the outer ring is not protected, easy to bump
