Problems solved by technology

But this technology is difficult to use on glasses, because the glasses lens is a resin, an organic polymer, and titanium dioxide, as a widely used photocatalyst, has a big disadvantage: its photocatalytic degradation does not have selectivity
If it is applied to eyeglasses, it has the potential to degrade the structural components of the lens

Abstract

The invention discloses a preparation method and products for a color-changing wearable self-cleaning concave lens. The preparation method comprises the following steps: (1) under the condition of 230-320 DEG C, heating and fusing thermoplastic plastic resin and additives by a thermoplastic machine and then filling into a forming chamber of a lens film, cooling and solidifying, opening the mold and taking out the lens; (2) putting silver bromide and copper oxide into a crucible of vacuum coating equipment, bombarding with electron beams under the condition of 2000 DEG C and evaporating, and then plating on the lens in the form of a film; and (3) putting diamond-like carbon, tin antimony oxide and titanium dioxide wrapped with silicon dioxide into the crucible of the vacuum coating equipment, vaporizing the three materials under the condition of 2000 DEG C to form a layer of uniform gas film, cooling and depositing on the lens. The raw materials adopted according to the preparation method are cheap and complete in function, and the products are suitable for vast people.

Description

technical field [0001] The invention specifically relates to a preparation method and product of a color-changing wear-resistant self-cleaning myopia lens. Background technique [0002] At present, the materials used as spectacle lenses in China mainly contain three categories: spar, optical glass and optical resin. Compared with optical glass, optical resin lenses have the advantages of light weight, impact resistance and easy processing and molding. Once launched, they quickly replaced optical glass and became the mainstream product of eyeglass lenses. [0003] Color-changing glass was invented in the United States in 1964. High-quality photochromic lenses should be transparent, free of emulsified color, short half-recovery time, and quick recovery. The original transmittance of the photochromic lens without base color is as high as about 90%. The original transmittance of the photochromic lens with base color can be as low as 60-70%. Generally, the transmittance of su...
