Method for producing fog-proof lens

Abstract

The method of producing antifogging lens includes cleaning substrate, vacuum plating wear resisting film, buffering layer and composite anti reflecting film, coating the mixture of zirconium oxide and zinc oxide through ion bombardment at 60-90 deg c inside vacuum filming cabin, and vacuum evaporating mixture of sodium fluoride, potassium chloride and magnesium fluoride to form covering nanometer level antifogging film. The present invention has film thickness controlling precision as high as 5 A, film covering rate as high as 100 %, and high antifogging effect.

Description

technical field [0001] The invention relates to a method for manufacturing an optical lens, in particular to a method for manufacturing an anti-fog lens. Background technique [0002] Anti-fog film lenses in the existing market use non-nano-scale vacuum coating process to produce anti-fog film. During the vacuum evaporation process, the precise control accuracy of the film thickness exceeds ±5A, and the film coverage cannot be controlled to maintain 100%, and its ingredients are also considered Whether the ingredients are complete, so the actual anti-fog effect is not satisfactory. The surface of the coated lens is still easily contaminated by tiny particles such as fog, especially when the temperature difference is large, the fog formed on the surface of the lens is difficult to quickly eliminate, which brings a lot of trouble to the wearer. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for manufactu...
