best way to clean glasses and keep them clean?

I bet they’re getting dirty when you’re taking them on and off or when you’re storing them. Always keep your glasses in a padded case. I like to keep a microfiber cleaning cloth wrapped around the glasses when I put them in the case just so the lenses don’t touch anything that might make them dirty. So proper storage, that’s step one. Step two is how you clean them. Go to an optometrist and ask for lens spray. It’s usually free if you buy glasses, anyway. Use the lens spray to clean your glasses. Don’t use water or your shirt or any other unspecialized cleaning method. Your lenses have a special coating on them that requires special cleaning tools. Only use a microfiber cloth and lens spray.

You really can't go wrong using a little dish soap. Just rub the soap into your glasses with a microfiber cloth or with your fingers, and then rinse them off with warm water. Then, just use another dry lens cleaning cloth to dry off the lenses.

I totally get how someone new to glasses would be surprised by how easily they get dirty. I kind of remember feeling the same way when I was prescribed glasses. The trick is to just never touch them. Always put your glasses on and take them off by holding the arms or frame. Don't put them on top of your head, either, as oil from your hair will get smeared on them. Just never come close to the lenses and you’ll be surprised how easy it is to keep them clean.

Lens wipes are super convenient to carry around so you can clean your glasses on the go. Keep a few packets in your pocket just in case they get dirty while you're out.

Sometimes gunk can get caught between the lenses and the frames. Pick it out with the end of a toothpick, but just be careful not to press too hard on the lenses.

Always keep some cleaner and a wipe with you. But don't use a packaged wet wipe. The chemicals will blur the lenses.
