Advise
It is best to only rinse your lenses in fresh water and then gently buff them dry with a lint free cloth. Do not use soaps or detergents as that will remove lens treatments.
Polycarbonate is an ideal material when it comes to lenses as it has excellent shatter-proof/impact resistant properties. It is also lightweight and can be flexed without breaking. However polycarbonate can scratch reasonably easily so we recommend that you keep your eyewear in its protective pouch when not in use. We would also recommend the use of a cord or strap so that if your glasses fall off they will be retained.
