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 film that fogs up your glasses. What now? Many of us grab the next best thing – a paper tissue, their tie or even the sleeve of a sweater or blouse. Actually, neither one is good for your lenses. Proper eyewear care extends the useful life of your glasses – and ensures better vision.
Many spectacles 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 causing scratches.
Consequently, your first choice for cleaning your lenses should be micro fibre cloths (e.g. by ZEISS). They remove grease and moisture without scratching your glasses or leaving marks. To regularly clean your glasses, first clean 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 micro fibre cloth (never rub hard). Tip: Practical tools for your daily eyewear care are special spectacles cleaning supplies (available in spray form or as towelettes, e.g. by ZEISS). These will clean your lenses carefully, thoroughly and have anti-static effects, which helps your glasses stay clear longer because they do not collect as much dust and debris.
Cleaning recommendation: Wash micro fibre cloths at temperatures not to exceed 40 degrees and do not add a fabric softener, as using one could cause your cloth to leave behind streaks the next time you clean your glasses!
Lens coatings with pearl off effects produce similar results (for instance LotuTec by 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; LotuTec also gives your spectacles a longer useful life.
The fact is, scratches are impossible to remove from both plastic and glass lenses, once they are there. Prevention is best. 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 the microfine scratch grooves, which will irritate your eyes.
To optimally care for your frame, we recommend you visit your optometrist every six months to have an ultrasound immersion performed. Virtually all optometrists offer this intensive cleaning service as a complimentary procedure that takes only a few minutes and gives your glasses and their frame back their original shine.
Remember: Your glasses need a home of their own. A hard case is the best place for your spectacles whenever you are not wearing them. If you lay them down somewhere and do not have the case handy, make sure the place is safe and that the lenses point upward at all times.
One more thing: Temperatures above 80 degrees will damage even the sturdiest of lenses and frames. In particular lenses made of organic matter 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 base glass and coating. However, no negative effects have been observed in ZEISS lenses while they are exposed to below freezing winter temperatures.
Remember: Long exposure to sauna temperatures or to the summer sun on your car’s dash board is bad for both – the case and the glasses.
Clean your spectacles quickly and gently: did you know about the pre-moistened lens cleaning wipes from ZEISS? Individually packaged, the wipes are quickly to hand in every situation. They are pre-moistened with a special combination of two active agents, free from aggressive cleaning substances and artificial fragrances.
