Polycarbonate is a lens material that is widely used for shatter-and-impact resistant lenses, and when combined with sturdy frame materials, makes for formidable eye protection.
In 2001, PPG Industries (Pittsburgh, Penn.) introduced a lens material called Trivex. Like polycarbonate lenses, lenses made of Trivex are thin, lightweight and much more impact-resistant than regular plastic or glass lenses.
Trivex lenses, however, are composed of a urethane-based monomer and are made from a cast molding process similar to how regular plastic lenses are made. This gives Trivex lenses the advantage of crisper optics than injection-molded polycarbonate lenses, according to PPG.
There are hazards of sunlight and bright light that are harder to understand; namely, ultraviolet rays (UV) and Glare (extreme brightness). Protecting your eyes from these distracting, even dangerous elements is equally important to eye protection.
