What lens is myopia good

First, glass lenses can be divided into white and red ones, with or without film. 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 is a kind of 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.

Third: as an optical material, the biggest advantage of crystal is its hardness, and the lens made of it is not easy to wear. Crystal lenses were once popular in 1920s-1930s. The lenses made of crystal lenses are durable, but the price is very expensive.
