Color-changing wear-resistant myopic lens, production method and glasses

Abstract

The invention belongs to the technical field of lens manufacturing, and discloses a color-changing wear-resistant myopic lens, a production method and glasses. The production method comprises the following steps: producing the myopic lens; performing process cleaning and process drying on the myopic lens; attaching a color-changing film or a polarizing film to the outer side of the lens by using a special shadowless glue process for the lens; attaching a hardened film to the outer side of the myopic lens by using a special shadowless glue process for the lens; spraying functional nano coatings on the inner side and the outer side of the myopic lens; and plating anti-fouling films on the inner and outer sides of the myopic lenses through process treatment. According to the production method provided by the invention, the surface of the myopic lens is subjected to process treatment in manners of attaching the hardened film, plating the anti-fouling films and spraying the nano coatings, the influence of non-uniform thickness of the myopic lens is avoided, the visual effects of different positions of the myopic lens are consistent, and the visual effect problem caused by a dyeing process is effectively avoided; the myopic lens has toughness and hardness and is resistant to high temperature; the nano coating sprayed on the surface of the myopic lens is resistant to friction; and stains are not easy to adhere to the surface of the myopic lens through the anti-fouling films.

Description

technical field [0001] The invention belongs to the technical field of lens production, and in particular relates to a color-changing wear-resistant myopia lens, a production method and glasses. Background technique [0002] According to different materials, lenses can be mainly divided into glass lenses, resin lenses, and PC lenses. Glass lenses are heavy due to the material, which affects their wearing comfort to a certain extent. Among them, glass lenses have been almost eliminated due to many shortcomings; resin lenses Spectacle lenses are the most popular because of their excellent performance and affordable price; the performance of PC lenses is almost worse than the former two, especially the dispersion control is not ideal, and the processing is troublesome; so conventional spectacle lenses are used A resin material is used as the lens material. Compared with glass lenses, resin lenses are lighter in quality; resin lenses have good light transmission, and in the ult...

Problems solved by technology

[0005] The original dyeing process itself is prone to uneven dyeing layer thickness due to gravity, and myopia lenses are of uneven thickness, and the light transmittance of different positions of dyed myopia lenses is different, the optical conditions are not good, and the visual effect is obviously deteriorated , the existing technology does not adopt the method of adding hard film, spraying nano-coating and coating anti-fouling film, which is limited by the thickness of the myopia lens, resulting in problems such as visual effects and sensory effects, and the original myopia lens strength is not high , easy to scratch, short life
