Proper cleaning of spectacles.
Maintain crystal-clear visibility with proper cleaning of your spectacles. Also find out which cleaning methods should be avoided so your spectacles last a long time.
Even though all spectacle lenses with premium coatings from Rodenstock are basically finished in such a way that they can be cleaned with a standard microfibre cloth, Rodenstock recommends cleaning the lenses under lukewarm running water with a pH-neutral cleaning agent, a diluted dishwashing detergent that does not have any refattening properties or a solvent-free spectacle care product.
Spectacle lenses must not be cleaned with harsh household cleaners, solvent-containing liquids, organic solvents (acetone etc.), acids or alkaline solutions. For drying, Rodenstock recommends a clean, fine-fibred microfibre or cotton cloth.
Avoiding scratches.
With dry cleaning dust particles which are on the lens are rubbed into the lens causing scratches.
Scratches also arise from cleaning with coarser fabrics, such as a T-shirt or tissue.
Incorrect cleaning should be avoided as scratches or other damage cannot be removed from plastic or mineral lenses. Even if the flaw only appears cosmetic, light disperses through the microfine scratches and irritates the eye.
TIP:
Your spectacles should undergo intensive cleaning at your Rodenstock partner optician every 6 months. A few minutes in the ultrasonic bath is all it takes to restore your lenses and frame to their original beauty.
Protecting the coating.
External factors may have negative impacts on the coating of your lenses.
Therefore, protect your spectacles against unusually high temperatures above 55 °C and high humidity. Avoid, for example, putting your spectacles down on the dashboard in a car parked in the sun or wearing your spectacles in the sauna.
