Multifunctional lens and preparing method thereof

Abstract

The invention relates to a multifunctional lens and a preparing method thereof. The lens comprises a base piece; a first membrane layer, a second membrane layer, a third membrane layer, a fourth membrane layer, a fifth membrane layer, a six membrane layer, a seven membrane layer, an eighth membrane layer, a ninth membrane layer, a tenth membrane layer and an eleventh layer are symmetrically sequentially arranged at the inner and outer surfaces of the base piece; the first, fourth and sixth membrane layers are Ti3O5 layers and have a thickness of 10-100nm; the second, fifth and seventh membrane layers are SiO2 layers and have a thickness of 50-100nm; the third membrane layer is a metal layer and has a thickness of 5-20nm; the eighth membrane layer is an ITO layer and has a thickness of 10-100nm; the ninth membrane layer is a nanosilver layer and has a thickness of 5-20nm; the tenth membrane layer is a high hardness layer and has a thickness of 10-50nm; the eleventh membrane layer is a fluoride layer and has a thickness of 3-10nm. The lens can effectively filter more than 30 percent of harmful blue light and dazzle light, can effectively relieve visual fatigue and the lens abrasion resistance is obviously improved by the high hardness layer.

Description

technical field [0001] The invention relates to the technical field of lenses, in particular to a multifunctional 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 exercise, so The degree of wear resistance of the lens is also a ...

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

[0006] In addition, when people's hands touch the lens, the oil and water stains on the hands are easy to leave marks on the lens, and these marks are not easy to erase, which will affect the effect of the user's observation of things. bring inconvenience

After the glasses are worn 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
