Description

technical field [0001] The invention relates to the field of photocuring, in particular to a wear-resistant photocuring lens. Background technique [0002] Lenses are used in everything from spectacle lenses used by the general public to high-precision optical drive read heads or optical lenses used in cameras. The traditional glass lens manufacturing process is made by optical grinding or precision cutting with diamond tools. Not only is the production difficult, the yield rate is low, time-consuming and labor-intensive, and the cost is high. When worn as glasses, the glass lens is easily damaged and cause harm. Therefore, the optics industry has developed optical molding processing technology to produce resin lenses to meet the huge market demand. [0003] The lens is easily scratched during use. Once scratched, the accuracy and light transmission performance of the lens will be affected, thereby affecting the service life of the lens. Contents of the invention [000...
