Embodiment 1

[0031] S1. Clean the acrylic substrate with a thickness of 1mm and dry it to obtain a clean acrylic substrate;

[0032] S2. Place the clean acrylic substrate on the jig, send it into the vacuum coating chamber and evacuate it. When the vacuum degree in the vacuum chamber reaches 5*10 -5 When the Torr is below, turn on the ion source and clean the surface of the acrylic substrate. When the vacuum degree in the vacuum chamber reaches 2*10 -5 When the Torr is below, the temperature in the vacuum chamber is controlled at 40-60°C and the evaporation rate is controlled at Use an electron gun to bombard the bottom layer and several film layer materials in order to form the bottom layer and several film layers sequentially on the outer surface of the substrate;

[0033] S3, keep the vacuum degree in the vacuum chamber at 2*10 -5 Below Torr, control the temperature in the vacuum chamber at 40-60°C and control the evaporation rate at A tungsten boat is used to heat the waterproof m...

Abstract

The invention belongs to the technical field of functional lenses, and relates to a lens capable of improving color contrast and saturation and a preparation method thereof. The lens comprises a substrate, a priming coat and a plurality of film layers, wherein the priming coat and the plurality of film layers are sequentially arranged on the outer surface of the substrate, the plurality of film layers are formed by alternately stacking low-refractive-index layers and high-refractive-index layers, and the high-low transmittance difference values of the plurality of film layers in blue, green, red and yellow spectral regions are all more than 50%. The lens provided by the invention has relatively large high-low transmittance difference values in blue, green, red and yellow spectral regions,and can improve the identification degree and definition of blue, green, red and yellow colors at the same time, so that the visual stereoscopic impression can be improved in an omnibearing manner; byadopting the same lens, the requirements of athletes in different sports scenes such as skiing, bicycles, speed skating and the like can be met at the same time, universality is achieved, the purposeof protecting the eyes and the bodies of the athletes is finally achieved, and meanwhile the competitive sports performance can be improved.

Description

technical field [0001] The invention belongs to the technical field of functional lenses, and in particular relates to a lens capable of improving color contrast and saturation and a preparation method thereof. Background technique [0002] Color weakness is a defect in color perception. Color weakness is manifested as a decline in the ability to perceive certain colors that normal humans can distinguish. There are many types of color weakness, including red color weakness, green color weakness, blue color weakness, yellow color weakness, etc. Red color weakness is manifested by insensitivity to red light and is affected by a dimming of the red end of the spectrum compared to normal individuals. Deuteranomaly individuals have a mutated form of the green pigment that shifts toward the red end of the spectrum, resulting in reduced sensitivity to the green region of the spectrum. Similar to red color weakness, green color weakness is poor at discerning small differences in hu...
