It only takes 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. What now? Many of us grab the next best thing – a paper tissue, your tie, or the sleeve of a sweater or blouse. Actually, none of them are good for your lenses. Proper eyewear care extends the useful life of your glasses – and ensures better vision.
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.
To optimally care for your frame, we recommend going to your eye care professional every six months for ultrasound immersion cleaning. Virtually all eye care professionals offer this intensive cleaning service as a complimentary procedure that takes only a few minutes and restores the original shine to your glasses and their frame.
Remember: Your glasses need a home of their own. A hard case is the best place for them whenever you are not wearing them. If you lay them down somewhere and do not have the case handy, make sure that place is safe and that the lenses point upward at all times.
One more thing: temperatures above 175 degrees will damage even the sturdiest of lenses and frames. In particular, plastic lenses should not be exposed to high temperatures or significant fluctuations in temperature. This could have an adverse impact on the durability of the coating (for instance the anti-reflective coating). Extreme temperature fluctuations may also cause ruptures due to the different structures of the base glass and coating. However, no negative effects have been observed in ZEISS lenses when they were exposed to below-freezing temperatures.
Remember: Long exposure to sauna temperatures or to the summer sun on your car’s dashboard is bad for both the case and the glasses.
