Abstract
The utility model discloses an one (b) plants ultraviolet protection lens and preparation method, and this ultraviolet protection lens includes glass substrate (1), its characterized in that glass substrate (1) is gone up and has been plated high refractive index membrane (2 in turn, 4, 6 2n, 10 <= n <= 25) and low refracting index membrane (3, 5 2n+1, 10 <= n <= 25), high refraction membrane (2, 4, 6 2n, 10 <= n <= 25) the thick 10~30nm that is of rete, low refracting index membrane (3, 5 2n+1, 10 <= n <= 25) the thick 25~50nm that is of rete, the high refractive index membrane (2, 4, 6 2n, 10 <= n <= 25) and low refracting index membrane (3, 5 2n+1, 10 <= n <= 25) 10~25 times in turn. The utility model discloses the ultraviolet protection lens visible light of preparation see through high, ultraviolet protecting effect is good, realizes ultraviolet ray protection and normal observe perfect unified, has solved and has worn sunglasses separation ultraviolet ray when preventing and treating the cataract, the visible light transmissivity is low to be influenced the people and observes the problem of examining.
Description
Technical field
The present invention relates to optical mirror slip field, especiallyOnePlant ultraviolet protection eyeglass.
Background technology
Long-term chronic ultraviolet radiation is to cause cataract that of paramount importance inducement occurs, and wearing against ultra-violet protective goggles is to prevent and treat the best means that cataract occurs. Sunglasses reaches by blocking or absorbing a part of light the object that prevents shielding of ultraviolet, is the most common against ultra-violet protective goggles. But sunglasses, intercepting the ultraviolet while, has also intercepted seeing through of visible ray, has reduced the observing effect of human eye.
Summary of the invention
The object of the invention is to, solved and worn sunglasses and intercept ultraviolet ray control when cataractous, visible light transmissivity is low, affects the problem of eye-observation. Provide a kind of visible ray good through height, ultraviolet radiation protective effect, realize ultraviolet protection and the normal ultraviolet protection eyeglass of observing perfect unity.
The invention discloses a kind of ultraviolet protection eyeglass, comprise glass substrate, it is characterized in that being outwards alternately coated with high refractive index film and low refractive index film by glass substrate on glass substrate, high refraction film bed thickness is that 10～30nm, low refractive index film bed thickness are 25～50nm, high refractive index film and low refractive index film alternately 10～25 glass substrates are alternately coated with high refractive index film and low refractive index film, high refraction film bed thickness is that 10～30nm, low refractive index film bed thickness are 25～50nm, high refractive index film and low refractive index film alternately 10～25 times.
Described high refractive index film is one or more in titanium dioxide film, zirconium dioxide film, ceria film.
Described low refractive index film is one or more in magnesium fluoride film, silicon dioxide film, di-aluminium trioxide film.
Brief description of the drawings
Fig. 1 is ultraviolet protection lens structure schematic diagram.
