Description

technical field [0001] The invention relates to an optical material, specifically a spectacle lens, especially a resin spectacle lens. technical background [0002] At present, resin lenses are in a priority position in the competition of the glasses market because of their light weight, high transparency, impact resistance, easy molding, and dyeability. The most domestically produced and sold resin lenses are 1.499 and 1.56 refractive index series, of which 1.499 resin lenses have higher impact resistance than 1.56, a dispersion coefficient of 58, and less dispersion, but due to the low refractive index, the lenses are thicker. However, the dispersion coefficient of the 1.56 refractive index lens is 38, and the impact resistance cannot pass the US FDA test (a steel ball with a diameter of 16mm is freely dropped from a height of 1.27 meters to impact the convex surface of the lens, and the lens should not be broken). [0003] According to the search, http: / / www.jiangteng.co...
