Anti-fog lens coating method

Abstract

The invention relates to an anti-fog lens coating method. The anti-fog lens coating method comprises the following steps that (1), a substrate is cleaned and dried; and (2), the inner surface and theouter surface of the substrate are coated separately, specifically, the two surfaces are coated with first films, second films, third films, fourth films, fifth films, sixth films, seventh films and eighth films separately. According to the anti-fog lens coating method, the multiple films on the lens can effectively prevent fog, metal layers can effectively improve the definition and the anti-dazzle and anti-blue-ray effects, therefore, the overall definition of the lens is improved, contribution is made to the definition and reality of the vision, and visual fatigue can be effectively relieved.

Description

technical field [0001] The invention relates to the technical field of lenses, in particular to an anti-fog lens coating method. Background technique [0002] With the continuous improvement of people's culture and living standards and the development of vision care work, glasses, as a simple optical device made to correct vision or protect eyes, have played an important role in people's daily life. Spectacles are usually composed of lenses and frames. From the function of lenses, it has the functions of adjusting the amount of light entering the eyes, increasing vision, protecting eye safety and clinically treating eye diseases. [0003] At present, there are many kinds of lenses, such as the common TAC polarized lens, which can block harmful light 100%, so it is very popular among consumers, especially suitable for outdoor sports. However, the lens will inevitably be scratched during exercise, so The degree of wear resistance of the lens is also a consideration for consum...

AI Technical Summary

Problems solved by technology

When driving at night, when the oncoming vehicle is coming, the driver will have a process of light adaptation, and when the vehicle passes by, there will be a process of dark adaptation, which can easily cause eye fatigue

In order to solve this potential safety hazard, people usually use a combination of electronics and optics, such as ADS crystal mirror, which is an upgraded product of the car sun visor, which can effectively prevent glare and automatically adjust the transmittance according to the external light intensity advantages, but it matches the model, if other models want to use this product, it must be installed separately, which greatly reduces its versatility, and the price of this product is high

[0005] The existing eyeglass also has the problem of easy fogging. There are two reasons for the fogging of the eyeglass: the first is the liquefaction phenomenon produced by the hotter gas in the eyeglass meeting the colder eyeglass; the second is the moisture on the skin surface sealed by the glasses. Evaporation, condensation of gas on the lens, which is the main reason why spraying anti-fog agent does not work
