Anti-reflective (AR) coatings are applied to spectacle lenses to help reduce glare from bright lights and overhead fluorescent lights. They are especially helpful for driving at night and for cutting down the glare from oncoming traffic. The Coating can peel off or become damaged if not cared for correctly but there are simple steps you can take to make sure you are cleaning your anti-reflective lenses properly.
- Only use a spray cleaner specifically for anti-reflective coatings or
- Wet the lenses on both sides, front and back, with cool or lukewarm (not hot) water.
- Apply a few drops of mild shampoo or soap to each side of the lenses. Gently rub the cleaner into the lenses or
- Place the lenses under running water as you continue to swirl them until they do not feel slippery or soapy.
- Dry lenses with a soft cloth such as an old, clean diaper or a micro fiber cloth designed for optical lenses. Do not use paper towels or tissues because the wood fiber in those products can scratch the AR coating.
- Do not use window cleaners or other chemical cleaners as they can peel off the coating.
The anti-reflection coating is especially recommended for HI-Index lenses, as these lenses have a lower light transmission, and with the AR Coating, it increases the light transmission. Anti-Reflection coating is ideal for people who spend a lot of time outdoors, work in dusty environments, spend a lot of time in front of the computer, television, video game etc.
