Because polycarbonate is the most impact-resistant lens material available, it is perfectly suited for people with reduced (or no) vision in one eye, as well as those who work or play in areas where there is an increased risk of lens breakage. Children’s lenses should also be made of polycarbonate.
Aside from its considerable strength, polycarbonate is a “high index” material, meaning it can be made thinner than other lens materials. This makes polycarbonate lenses particularly suitable for those with strong prescriptions. In addition, polycarbonate is the lightest lens material. When you add up all these considerable advantages, polycarbonate should be high on your list when it comes to choosing prescription lenses.
Polycarbonate was developed in the 1970s for aerospace applications. It is currently used for the helmet visors of astronauts and for space shuttle windshields. Polycarbonate lenses should be treated with a scratch-resistant coating.
