Abstract
The invention discloses an anti-ultraviolet spectacle lens and a preparation process thereof. The anti-ultraviolet spectacle lens is prepared from the following raw materials: a resin material, a light screener, an ultraviolet absorber, a radical scavenger, and a compatibilizer. The preparation process comprises the following steps: sequentially putting the light screener, the ultraviolet absorber, the radical scavenger and the compatibilizer in an organic solvent, magnetically stirring until a solution is in an emulsified shape to obtain an emulsion; putting the resin into a hopper to be melted to obtain a homogeneous material; putting the homogeneous material in an extruder for extrusion granulation to obtain resin particles; putting the resin particles in a spectacle lens mold, adding a solvent and the emulsion, heating, insulating, demolding and cleaning to obtain an anti-ultraviolet spectacle lens. The spectacle lens provided by the invention has reliable ultraviolet resistance, and can avoid eye damage caused by ultraviolet irradiation.
Description
technical field [0001] The invention relates to the field of glasses, in particular to an anti-ultraviolet spectacle lens and a preparation process thereof. Background technique [0002] People use glasses to recognize visible light to observe things. In addition to the visible light range in natural light, the higher frequency ultraviolet light region also affects people's normal life. Important target organs for absorbing UV rays are the skin and eyes. A certain intensity of ultraviolet rays is necessary to promote people's normal metabolism. However, in the scorching summer, the proportion of high-frequency ultraviolet rays in solar radiation increases, and it is necessary to wear functional glasses to protect the eyes and avoid excessive absorption of ultraviolet rays. [0003] Functional glasses are glasses designed to weaken or eliminate unfavorable factors for certain specific environments. Obviously, sunglasses are a common type of functional eyewear. Sunglasses...
