Abstract

The invention relates to a PMC (polymer-matrix composite) radiation-proof resin lens, comprising the following components in percentage by weight:47-50% of a first mixture, 50-53% of a second mixture, 0.05-0.10% of an ultraviolet absorbent, 0.045-0.055% of a blue organic pigment, 0.025-0.035% of a red organic pigment, 0.04-0.07% of a mold releasing agent, and 0.06-0.10% of dibutyltin dichloride. By adopting the PMC radiation-proof resin lens, the visual field aberration caused by edge dispersion of a substrate can be greatly improved, the image sharpness is improved, and the shock resistance passes through and surpasses an FDA (Food and Drug Administration) shock resistance safety certification of America, so that the safety for wearing the resin lens is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of lens materials, and in particular relates to a PMC radiation-proof resin lens and a manufacturing process thereof. Background technique [0002] With the development of the glasses market, consumers' awareness of resin lenses has been continuously improved, and at the same time, higher requirements have been put forward for the performance and functions of the products, which has caused the sales of low-value lenses to gradually decline, while high-value lenses with excellent performance (including Safety) lenses are favored by consumers. At present, there are almost no manufacturers independently developing and researching high-definition lenses in the domestic market, and almost all high-definition products are imported. Not only are the prices expensive, but their quality and performance cannot meet the requirements of consumers. Therefore, it is very necessary to develop a resin lens with high refrac...
