METHOD FOR MANUFACTURING SUNGLASS LENSES, AND SUNGLASS LENS

摘要

The invention relates to a method for manufacturing sunglass lenses, and a sunglass lens. The method comprises the following steps: S1, manufacturing of a color powder sheet: a color powder is added to a color powder sheet base material in a corresponding proportion to manufacture a plain color powder sheet; and S2, manufacturing of a lens: the color powder sheet manufactured in S1 is fixed in a cavity of a lens mold, a molten colorless and transparent lens base material is injection-molded in the cavity of the lens mold and is then integrally combined with the color powder sheet in the cavity of the lens mold, and demolding is carried out after cooling, so that a sunglass lens is manufactured. The problem of chromatic aberration of existing sunglass lenses or scratches of films on the existing sunglass lenses is solved.
