Sunglass coated glass lens and preparation method thereof

Abstract

The invention discloses a sunglass coated glass lens and a preparation method thereof. According to the sunglass coated glass lens, a planar white glass sheet serves as a base material, the thicknessis small, the texture is reliable, the lens cannot deform after being framed, the diopter of the lens cannot be changed, and the problems that a resin lens becomes yellow for a long time and the optical property is changed are solved; and meanwhile, the planar white glass sheet is used as the base material, so that the permeability is good, and the color reducibility is good. Moreover, a coating layer formed by high-temperature coating is stable, can tolerate high temperature and is not easy to crack and the like, so the glasses have good wearing sensory comfort, and eyes are effectively protected. Furthermore, the coated glass lens of the sunglasses takes the planar white glass sheet as the base material, and the outer surface of the lens is coated with an anti-fingerprint coating, so that the wear resistance, scratch resistance, water resistance and dust resistance of the lens can be effectively improved, and the service life is long. According to the preparation method disclosed bythe invention, the white glass sheet is used as thhe base material, and the sunglass coated glass lens with stable coating and excellent optical effect can be prepared.

Description

technical field [0001] The invention relates to the technical field of sunglasses lenses, in particular to a sunglass coated glass lens and a preparation method thereof. Background technique [0002] In sunlight, the human eye usually adjusts the luminous flux by adjusting the size of the pupil. When the light intensity exceeds the adjustment ability of the human eye, it will cause damage to the human eye. Therefore, in outdoor activities, especially in summer, it is necessary to use sunglasses to block the sun, so as to reduce the fatigue caused by eye adjustment or the damage caused by strong light stimulation. [0003] At present, the lens materials of most sunglasses products on the market are made of resin materials. The base of resin materials is soft, and the film layer is prone to cracks after surface coating, which cannot withstand high temperatures. The lenses are easily deformed after framing, resulting in changes in diopter. It affects the comfort when wearing, ...

AI Technical Summary

Problems solved by technology

[0003] At present, the lens material of most sunglasses products in the market is made of resin material. The base of the resin material is soft, and the film layer is prone to cracks after surface coating, which is not resistant to high temperature. The lens is easily deformed after framing, resulting in changes in diopter. Affect the comfort when wearing, and at the same time, there will be some harm to eyesight

Moreover, the lenses of resin materials are soft, not wear-resistant, and have poor scratch resistance, which will also affect the service life

[0004] In addition, resin material lenses have high transmittance in the red light band, poor color reproduction, and poor visual effects

At the same time, the overall permeability of the sun lenses made of resin material is not good, and the visual effect gets worse the more you wear them
