For many people, glasses are essential to see clearly. It is important to take proper care of your eyeglasses so that your vision is the best that it can be, and you don't have to spend money fixing or replacing them. You should clean your glasses regularly, and when you handle them, take precautions to prevent scratching. With proper maintenance, your glasses can last for years.

1. Don’t wipe lenses when they’re dry. Any debris on their surface or dust in the cleaning cloth could cause scratches.

2. Don’t wipe lenses with a tissue, paper towel, or paper napkin. They can have a rough surface. When cleaning your glasses, it will be better if you use specialized glasses cleaning cloth. FYTOO will give away two pieces of super-soft microfiber cloth in your package, helping you clean your glasses more properly.

3. Don’t use ammonia, bleach, vinegar, or window cleaner, which can harm lenses and their coatings. (Most lenses are now coated, usually with an anti-reflective layer.)

4. Don’t spit on your lens. While spit is a handy cleaning solution, “saliva may contain oil or something else that’s damaging,” says American Optometric Association spokeswoman Susan Thomas. Exhaling on lenses before cleaning doesn’t get them very wet, and the association doesn’t recommend it. You can use glasses cleaning solution to get the surface wet and remove the dust and debris from it.

5. Don’t put unprotected glasses in a purse, pocket, or bag.

6. Don’t regularly place glasses on a sink or vanity top. Spatter, sprays, and cosmetics can soil lenses, and hair spray or perfume can damage anti-reflective coating.

7. Don’t leave glasses in a hot car. “Especially avoid the top of the dashboard,” Thomas advises. “The windshield will act like a magnifying lens.”
