Personally, it is the same as you clean your regular lenses. Just wash the lenses under tap water. But if you want to better protect your eyeglasses, you shall obey the suggestions from your optician. You can consult him/her what are the best lens cleaners for your eyeglasses lenses. Usually, most opticians will suggest you not clean your eyeglasses with harsh chemicals which may damages the anti-reflective coating on the glasses.
If you don't want to damages the anti-reflective coating on the glasses, you are suggested to use a non-toxic ammonia and alcohol-free cleaning solution. You shall spray some solution on the lenses, and then rub it with a microfiber cloth gently in case to causes scratches on the lenses. Next, clean the lenses under clean water. And dry the lenses with a dry microfiber cloth. Hope this can work for you.
When smudges or streaks appear on your glasses, grab some type of cloth to wipe them away %u2013 but don%u2019t use any old napkin or tissue that might be lying around. Rough materials can scratch the anti-reflective coating. Choose a microfiber cloth designed specifically for glasses to ensure that you don%u2019t ruin the coating. No matter what type of cloth you use to clean your glasses, do not wipe them when they're dry. Without lubrication, dirt or debris on the surface of the lenses or in the cloth can scratch your glasses. Wet your lenses with warm water before wiping them with a microfiber cloth. For stubborn smudges or dirt, use a cleanser specifically for eyeglasses or a mild liquid soap. Avoid harsh products, such as window cleaner, bleach, alcohol, ammonia or even vinegar, which can damage the anti-reflective coating. Rinse the lenses with warm water before drying with a clean, dry microfiber cloth. Pre-moistened lens-cleaning cloths work well when you%u2019re on the go.
Hand soap or liquid soap diluted in water is ideal. Gently rub the soapy water on the lenses. Do not use a rough sponge or scouring pad, as this may scratch the anti-reflective coating. As an alternative to soapy water, it is possible to use any lens cleaning fluid that is "AR safe."
