The GDU lens is coated with a special anti-reflective coating that is very sensitive to skin oils,
waxes and abrasive cleaners. CLEANERS CONTAINING AMMONIA WILL HARM THE ANTI-
REFLECTIVE COATING. It is very important to clean the lens using a clean, lint-free cloth and
an eyeglass lens cleaner that is specified as safe for anti-reflective coatings.
