Wash your hands to avoid adding more debris to your lenses
Rinse your glasses under lukewarm tap water
Add a small drop of dish soap to your lenses
Gently rub the lenses between your fingers to clean them
Rinse your glasses and shake off the excess water
Dry your glasses with a microfiber cloth
You probably got a microfiber cleaning cloth when you purchased your glasses, but if you didn’t, you can use a lint-free towel instead. Make sure the towel hasn’t been washed with fabric softener or dried with a dryer sheet, these can leave residue on the towel that will smear your lenses.
Your best option is to run tap water over your lenses until the spots disappear, then dry them with a lint-free towel or a microfiber cloth. If the spots don’t dissolve after a few moments, lightly rub them with your finger. However, if you don’t have access to a sink, generously applying a lens cleaning solution can dissolve those pesky spots too.
The best way to clean blue light glasses is the same as standard prescription lenses — using tap water and soap. But remember: some blue light glasses are made from less durable materials that could warp when heated, so be sure to avoid hot water.
Don’t use hot water, it could warp the lenses
Avoid soap with lotion, it will smear your lenses

It’s also a good idea to check the rims of your blue light glasses for buildup. These glasses tend to be worn while looking straight ahead at your computer, so you might not notice dirty edges. You can use a cotton swab to clean these sections.
Your lenses might have sand or other scratch-causing debris, so be liberal with the lens cleaner. Too little could result in scratches. If possible, it’s always a good idea to run your glasses under tap water first to reduce the chance of scratches.
Apply the cleaning solution to both sides of your lenses
Rub the microfiber cloth in a circular motion to remove the cleaner
Check your lenses for oily spots and repeat if necessary
Be careful: if your glasses have an anti-reflective (AR) coating, not all cleaning solutions are safe. Make sure your cleaning solution is approved for use on AR lenses, or go with the soap and tap water option.
Believe it or not, a lot of really soft materials can scratch your lenses. In fact, most fabrics will either scratch your lenses or just push around the grime and cause more smudges.
It’s tempting, but never use your shirt to clean your glasses. Even super clean clothing is likely to cause scratches and most fabrics will result in more smudging thanks to residual soap or fabric softener.
Don’t reach for a napkin either. Napkins (and paper towels) will cause small scratches over time and almost always leave lint on your lens.
Overall, the best glasses cleaning cloth is a microfiber cloth. They’re really good at trapping oil and dirt without scratching your specs.
If you don’t have a microfiber cloth on hand, using a lint-free towel can work. If you wash your glasses and don’t have a microfiber cloth or a safe towel available, it’s better to let your glasses air dry than to use a harmful fabric.
Rubber can act like a sponge, absorbing oils and sweat, so leaving padding uncleaned could reduce its lifespan. Finally, you might be in the habit of cleaning your sunglasses with your breath then rubbing them on your shirt. That might be convenient, but it’s not effective. Beyond causing scratches, this method just smears around oils and results in a dirtier lens.

Polarized lenses are sensitive, so it’s best to stick with water in most situations. However, using a lens cleaning solution might be necessary if you’re dealing with a particularly stubborn smudge. If that’s the case, use a lens cleaner that doesn’t contain alcohol.
Finally, it’s important to remember that not all sunglasses are polarized. If you have non-polarized sunglasses, cleaning your lenses with soap or a lens cleaning solution is just fine.
