Lens Materials

When we choose the lenses, there are always many kinds, and the basic differences among different lenses is the material, in general, the lens material could be classified into the following ones.

Hard Resin: Hard Resin is a kind of plastic, and now it is the most widely used lens in the world. Being the replacement for the mineral lens, it is lighter and stronger, and for its weakness of soft, which is susceptible to scratching, it is solved by Coating, so more comfortable to wear.

Polycarbonate: Polycarbonate is a special kind of plastic, it is accepted for some material in the aircraft like windows, so it’s easy to see that it is very strong to face the impact, and it’s the most impact-resistance lens material now. It also has the UV protection. PC lens is most used for sportswear and children.

High Index Plastic: Advanced type of Hard Resin lens, It is thinner, lighter, and pre-treated with UV protection, and performance also good in Abbe Value, which make it comfortable to wear as well as nice looking.

Glass: It is the original ophthalmic lens material, due to high transmittance and anti-scratches performance ,it is still very popular in some area,. Especially near the desert area, where the wind blows with sands, the mineral lens is still the best choice for daily use.
