Abstract
The present invention discloses a method for manufacturing a high-energy blue light resistant resin lens, which comprises: providing a stirred resin monomer, wherein the resin monomer is mixed with an anti-blue light absorber; filling the resin monomer into a glass mold through a glue gun, wherein the glass mold has an optical concave mold and an optical convex mold, wherein the optical concave mold and the optical convex mold are connected by adhesive tape, and a filling cavity in the middle is reserved, and a honeycomb-shaped micro-light unit is arranged on the surface of the optical concave mold, and the micro-light unit is concave; curing the glass mold filled with the resin monomer to obtain a resin substrate; then performing infrared stress elimination, cleaning and drying, and then coating a functional film layer; and finally taking out for inspection and packaging. The present invention provides a glass mold with a micro-light unit, and curing and molding with a resin monomer mixed with an anti-blue light absorber, thereby improving the blue light resistance to high-energy filtering and weakening, and then performing infrared stress elimination, and coating various functional film layers, thereby achieving high-reliability product quality of the resin lens.
