It takes only a second – a greasy fingerprint suddenly appears on your lens, debris and dust make it harder for you to see or moisture creates a film that fogs up your glasses.
Your first choice for cleaning your lenses should be ZEISS microfiber cloths . They remove grease and moisture without scratching your glasses or leaving marks. To clean your glasses, first rinse them under running water to remove dust and dirt. Next, add a pH-neutral dishwashing detergent to the water, rinse again and gently dry the lenses with a microfiber cloth (never rub hard).
Practical tools for your daily eyewear care are special lens-cleaning supplies (available by ZEISS in spray form or as wipes). These will clean your lenses thoroughly without damaging them. They also have an anti-static effect, which helps your glasses to stay clear longer because they do not collect as much dust and debris. Scratches are impossible to remove from both plastic and glass lenses once they are there, so it is best to prevent them.
Wash microfiber cloths at temperatures not to exceed 100° F and do not add fabric softener, as this could cause your cloth to leave streaks the next time you clean your glasses!
