However, with time, man created a few new materials that could replace glass and provide additional benefits. Plastic was one such material. Today, 50% of the lenses used in the world are made with plastic because plastic is lighter and more reliable. It is also cheaper in comparison. There are also polycarbonate lenses, which are slowly gaining popularity because of their benefits.

About Polycarbonate Lenses

These lenses came into existence only in the 70s while plastic has been used for a longer period of time. In order to make lenses with polycarbonate, the material is broken down into pellets and these pellets are heated. After that, they are molded into lenses under very high pressure and allowed to get cool in order to come up with finished lenses in just a span of minutes.
