Many eyeglass wearers are not even aware of the fact that improper cleaning is hard on their glasses. Take tissues for example: If you use one to clean your lenses, they pick up debris from the lens and scratch it as you clean. These small scratches will eventually wear down the glass and cause scratches.
Consequently, your first choice for cleaning your lenses should be microfiber cloths (like those made by ZEISS). They remove grease and moisture without scratching your glasses or leaving marks. To properly clean your glasses, first rinse them under running water to remove dust and rough debris. Next, add a pH-neutral dishwashing detergent to the water and gently dry the lenses with a microfiber cloth (never rub hard). Tip: Practical tools for your daily eyewear care are special eyeglass cleaning supplies (available in spray form or as towelettes, such as those offered by ZEISS). These will clean your lenses carefully, thoroughly and provide anti-static effects which help your glasses stay clear longer because they won’t collect as much dust and debris.
Cleaning recommendation: Wash microfiber cloths at temperatures below 100 degrees and don't add fabric softener, which could cause your cloth to leave behind streaks when you clean your glasses!
Lens coatings with beading produce similar results (for instance,DuraVision Platinumby ZEISS), which make it hard for undesirable debris, dust or moisture to get stuck on your lenses. Not only will this cut down the amount of cleaning you need to do significantly; a coatingalso gives your eyeglasses a longer service life.
The fact is, scratches are impossible to remove from both plastic and glass lenses once they are there. Prevention is the best approach. If your glasses get scratched, you should replace them quickly. Although most people believe that the defect is only a cosmetic one, the light is actually diffused by minute grooves and will irritate your eyes.
