Which kind of myopia lens is good

First: glass lenses: glass lenses are divided into white and red ones. White and red ones have two kinds of films and no films. The glass has the best wear resistance, but it is fragile, and the glass lens is heavy and uncomfortable to wear. So now few people use it, they usually choose other lenses to replace it.

Second: resin lens: resin lens is an optical lens made of resin. Light and wear-resistant, light transmittance can reach 98% after coating, strong impact resistance, wide range of luminosity, general eye needs can be met. Because of its special chemical structure and can be used as this latex paint and adhesive, it is paid attention to.
