Knowledge of glasses lenses
1. What kinds of lens materials are there? Natural materials: crystal stone, high hardness, not easy to grind, can transmit ultraviolet rays, and has birefringence. Artificial materials: including inorganic glass, organic glass and optical resin. Inorganic glass: It is smelted from silica, calciu...Read more -
The misunderstanding of sunglasses selection.
Misunderstanding 1: All sunglasses are 100% UV resistant Let’s first understand the ultraviolet light. The wavelength of ultraviolet light is below 400 uv. After the eye is exposed, it will damage the cornea and retina, resulting in solar keratitis and corneal endothelial damage.High-qualit...Read more
