To get the best optics, you need an anti-reflective glare treatment on your lenses. It is as simple as that. An anti-reflective glare treatment on your lenses will block out the internal reflection that happens with a normal cut pair of lenses. This aids you in driving at night, seeing the computer, working under fluorescent lighting and it protects you from UV exposure outside. Anti-reflective glare treatments can also increase scratch resistance and stop dirt, smudges, and dust from sticking to your lenses. A clean lens is a clearer lens!
