Caring for your safety glasses is important because one of the most common causes of scratched lenses is improper cleaning. Typically, safety glasses are made of polycarbonate lenses which means it is easier to scratch the lenses if not cleaned properly. The first thing you want to do is blow any loose debris off the lenses. Then, use the inside of the microfiber lens cleaning cloth that is provided with each of our glasses sold to wipe the lens. NEVER EVER use dish soap or other glass cleaning household products because it can remove certain lens coatings. Be sure to also store your glasses in a hard case that way it can protect the glasses from an accidental falls.
