MULTILAYER THIN-FILM PLASTIC GLASSES LENS HAVING HIGH-CONCENTRATION COLORING EFFECT AND LOW-REFLECTION EFFECT AND MANUFACTURING METHOD THEREFOR

摘要

The present invention relates to: a multilayer thin-film plastic glasses lens having both a high-concentration coloring effect through the absorption of the metal and a low-reflection effect by forming a multilayer thin film of a metal and a dielectric on the surfaces of a plastic glasses lens; and a manufacturing method therefor. In the multilayer thin-film plastic glasses lens having a high-concentration coloring effect and a low-reflection effect, of the present invention, a low refractive index dielectric and a metal thin film having an extinction coefficient are alternately deposited on a convex surface, and a dielectric having a high refractive index and a dielectric having a low refractive index are alternately deposited on a concave surface. According to the present invention, the same coloring effect as that of a conventional colored lens can be implemented together with a low-reflection effect by selectively arranging a metal having an extinction coefficient and a dielectric and adjusting a thickness, there is no limit to coloring according to a material (refractive index), there is no color-change problem according to a time elapse, and the lens can be mass-produced. The multilayer thin-film plastic glasses lens, according to the present invention, maintains an eyesight correction function as is while adjusting the transmissivity of a visible ray region and the color of a coloring effect, and thus the multilayer thin-film plastic glasses lens can be used as a glasses lens for various uses such as for a driver, for leisure and for computer work.
