In the past, when choosing glasses, consumers typically had a choice of glass or standard plastic lenses, but modern innovations have allowed for the creation of new chemical compositions that produce several advantages over traditional options.
Polycarbonate was originally invented by members of the aerospace industry. This new and stronger type of plastic was specifically intended to fit the helmet visors that astronauts wore, providing them maximum protection.
Needless to say, polycarbonate lenses are extremely shatter-resistant, making them exceptional for use in sports, for children, or for people who perform jobs that require protection over the eyes. Polycarbonate is also used to make airplane windows, police riot shields, and bulletproof windows. Polycarbonate lenses are 10-times stronger than glass or typical plastic lenses and exceed FDA's requirements for impact resistance by more than 40 times. This is tough stuff!
Not only are polycarbonate lenses strong, but they are light – lighter than regular plastic or glass. They are also thinner, so they are a good choice for glasses wearers (and especially heavy prescription wearers) who crave for the end of bug-eye days and typically worry about the weight and sleekness of their glasses.
For sunglasses, polycarbonate lenses are particularly superior because they naturally offer the eyes protection from ultraviolet radiation. Polycarbonate alone blocks over 99% of the sun's harmful UV rays without any added coating or substance.
Most of Olympic Eyewear's bulk sunglasses are fitted with polycarbonate lenses, from our Biohazard sunglasses and DG Sunglasses to our Choppers sunglasses. All of our products are compliant with United States and International UV standards. For obvious reasons, polycarbonate has become a first choice alternative lens material, so you can shop with confidence that you are obtaining good quality sunglasses products.
