Preparation method of ophthalmic lens with low reflection coating by wet process and ophthalmic lens using it

摘要

The present invention relates to a method of manufacturing a low-reflection coated spectacle lens manufactured by a wet process and a method of manufacturing the same. According to the manufacturing method of the present invention, a high refractive index hard coating liquid having a refractive index of 1.60 or more A primer coating layer is formed with an organosilane containing an amino group thereon, a low refractive coating liquid having a refractive index of 1.40 or less is coated thereon, and then thermally cured to form a low refractive coating layer It is possible to economically mass-produce a low-reflection coated spectacle lens. Further, in the production of the above-mentioned low reflection coated spectacle lens, the adhesion force and the heat resistance can be greatly improved by forming the organosilane containing an amino group between the high refractive index hard coating layer and the low refractive index coating layer as a primer coating layer , An optical lens, a plastic shield, a goggle, and the like.
