Crystal lenses are used to help the eyes resist external pressure, acidic environments, high temperatures, etc.
Crystal lens is made of natural crystal stone, which is hard, high temperature resistant, and corrosion resistant. You should pay attention to the choice of natural components of crystal lenses because some providers will mix the artificial crystal material and natural crystal. Buyers should carefully identify, so as to avoid adverse reactions after wearing.
Benefits of natural crystal lens
Impact Resistance - natural crystal features high hardness. When the eyes are subjected to external force, crystal glasses can withstand part of the external force to reduce the damage to the eyes.
Acid resistance - crystal is resistant to acidic solutions, such as hydrochloric acid, sulfuric acid, etc. People engaged in this kind of work with crystal glasses, can achieve better eye protection effect.high temperature resistance: crystal lenses have hard texture, high temperature resistance, so they can help resist high temperature, so as to reduce the heat wave stimulation and impact on the eyes.
In addition, crystal glasses are more expensive, the absorption of infrared and ultraviolet light is lower than the general lens. You should better not wear them for a long time. Long-term exposure to ultraviolet light may cause some damage to the eyes.
