Anti-dazzle and anti-blue-light lens and preparation method thereof

Abstract

The invention discloses an anti-dazzle and anti-blue-light lens and a preparation method thereof. The anti-dazzle and anti-blue-light lens comprises a plastic titanium substrate, the outer surface ofthe top end of the plastic titanium substrate is provided with a first reinforcing layer, and the outer surface of the top end of the first reinforcing layer is provided with a first waterproof layer.According to the anti-dazzle and anti-blue-light lens and the preparation method thereof, a holmium oxide layer and a samarium oxide layer are arranged in an anti-dazzle and anti-blue-light layer toimprove the absorption of ultraviolet light and light of short-wave blue light regions; when evaporation coating is performed, plating is performed for 1 to 2s, pausing is performed afterwards, plating layers form a to-be-solidified state on the surface of the lens to slow down the mutual permeation between the plating layers and improve the uniformity of the plating layers, after each layer is subjected to evaporation coating, the uniformity of the plating layers can be improved and the integrity of the plating layers can be better ensured by shaking the lens, and after plating coating is completed on the upper layer, the next layer is subjected to evaporation coating immediately to improve the firmness of the connection between the plating layers.

[0002] Anti-glare and anti-blue light lenses are spectacle lenses that can prevent blue light and glare at the same time. However, with the development of science and technology, people have higher and higher requirements for anti-glare and anti-blue light lenses. Meet people's needs;

[0003] The traditional anti-glare and anti-blue light lens and its preparation method have certain disadvantages. The evaporation coating is not uniform. The existing lens evaporation coating method is to sequentially coat each layer on the lens. Some layers with a small thickness, when using the evaporation coating , due to the small coating material, uneven coating thickness and coating damage are prone to occur, which not only affects the effect of anti-glare and anti-blue light, but also produces unqualified lenses, resulting in a waste of resources. Secondly, the existing There are two situations in the evaporation coating process: one is that the time interval between the coatings is short, the previous raw material has not solidified, and the other raw material has been in contact with the lens, and the raw materials are prone to mixing, making various raw materials Uneven distribution will affect the effect of anti-glare and anti-blue light. The other is to stop for a certain period of time between each coating to let the previous raw material solidify. Although this method ensures the thickness of each coating, but due to the previous one The raw materials have been solidified, and it is difficult for the next raw material to be tightly bonded to the previous coating, resulting in imprecise bonding between various coatings. Therefore, we propose an anti-glare and anti-blue light lens and its preparation method
