Sterilizing, anti-dazzle, anti-reflection and wear-resisting lens and preparing method thereof

Abstract

The invention relates to a sterilizing, anti-dazzle, anti-reflection and wear-resisting lens and a preparing method thereof. The lens comprises a substrate. The inner surface of the substrate is sequentially provided with a first film, a second film, a third film, a fourth film, a fifth film and a sixth film from inside to outside, the outer surface of the substrate is sequentially provided with a first film, a second film, a third film, a fourth film, a fifth film and a sixth film from inside to outside, and the first film, the second film, the third film, the fourth film, the fifth film and the sixth film of the inner surface and the first film, the second film and the third film, the fourth film, the fifth film and the sixth film of the outer surface are symmetrical. The first films and the third films are trititanium pentoxide layers, and the thickness of the first films and the thickness of the third films both range from 10 nm to 100 nm; the second films and the fourth films are silicon dioxide layers, and the thickness of the second films and the thickness of the fourth films both range from 50 nm to 100 nm; the fifth films are nano-silver layers, and the thickness of the fifth films ranges from 5 nm to 20 nm; the sixth films are high hardness layers, and the thickness of the sixth films ranges from 10 nm to 50 nm. The preparing method includes the following steps that 1, the substrate is washed; 2, the inner surface and the outer surface of the substrate are coated with the films. By means of the lens, the definition can be effectively increased, the anti-blue-light effect can be effectively improved, dazzling can be prevented, the wear resistance can be improved, bacterium growth can be effectively inhibited, and the lens has the harmful-bacterium killing performance.

Description

technical field [0001] The invention relates to the technical field of lenses, in particular to a sterilizing, anti-glare, anti-reflection, anti-reflective and wear-resistant lens and a preparation method thereof. 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 exerc...

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] In addition, after wearing glasses for a long time, the lenses are not only easy to breed bacteria, but also easy to absorb fine particles such as dust in the surrounding environment, which is not conducive to the health of the wearer, pollutes the lens, and affects its light transmission.
