The invention belongs to the technical field of surface processing, in particular to a method for preparing high metallic texture high transmission lens. The method comprises the following: step one, optical filming: a product to be filmed is subjected to five-layer optical filming in an optical filming device; wherein the first layer is TiO2 filming; the second layer is SiO2 filming; the third layer is TiO2 filming; the fourth layer is SiO2 filming; the fifth layer is TiO2 filming; step two, priming coat spraying: priming coat is sprayed on the surface of the product filming to be roasted inan oven; step three, UV finishing coat spraying: the UV finishing coat is sprayed on the surface of the product filming to be roasted by the oven and solidified by a UV furnace. The plastic lens processed by the method has strong metal texture, friction and scratch resistance and high transmission rate reaching 98 percent.
