The best way to clean glasses lenses

Many people must realize that cleaning their lenses, if not done correctly, can actually be harmful.

Here are four easy steps to clean glasses lenses the right way and avoid causing any damage

Step 1 – Wash and dry your hands

The first step to having spotless glasses is ensuring your hands are clean, as you don’t want to pass grease or dirt to the cloth or lenses. Wash your hands thoroughly with soap and dry them with a lint-free towel.

Step 2 – Spray with optical cleaner

Use a dedicated lens cleaning spray on each lens of your glasses. Any optical glasses spray is suitable. You can find these at most opticians, pharmacy stores, and supermarkets.

Step 3 – Clean with a microfiber cloth

After you apply the optical cleaner, you can then use a microfiber, lint-free cloth to wipe away any smudges or debris gently. If you’re wondering where to get a proper microfiber cloth, you’re in luck. SmartBuyGlasses includes a free lens cleaning cloth with each pair of glasses.

Step 4 – Store them in a protective case

Once your glasses are all clean, the next important step is to store them properly to ensure they stay that way. Store them in a hard, protective case with their lenses facing up. This will keep your glasses from being squished.


It might be convenient, but cleaning your glasses with your t-shirt or other items of clothing can actually damage th elenses. This is due to the small fibers and uneven surfaces that can create tiny scratches over time,

You can also use the optical lens spray on your glasses’ frames since it will be gentle enough to clean general dirt. If you wear prescription glasses while performing strenuous activities, it’s important to clean them frequently to get rid of any dirt build-up.

The worst way to clean your glasses

Now that you know all the steps to best clean your glasses’ lenses and frame take a look at what is important to avoid when cleaning your eyeglasses.

Don’t use tissue paper and clothing

Never use shirts, cotton tissues, napkins, paper towels, or dishwashing soap. Using any of these can damage the lens coating over time and void any applicable warranty on the eyeglasses.

Though these everyday items might seem harmless, they are made of tiny materials and have uneven surfaces that may scratch your lenses. These scratches will distort the way light passes through your glasses and lead to vision issues or eye irritation in the future. 

Don’t use saltwater

Saltwater significantly damages any lenses, especially when they have lens coatings. Many things rust or degrade when regularly exposed to the salty air near the beach or salt water.

It’s important to remember that lenses should not be exposed to salt water, as they can get damaged, and it will not count as a manufacturer’s defect. Remember to keep them in a safe place and away from the ocean on your next beach day.

Don’t use dish soap, window cleaner, or saliva

Avoid using saliva to wipe off smudges from your glasses. Saliva is unhygienic and may spread more dirt and germs around. Another thing to avoid on your glasses is any cleaning solution made for general surfaces or glass.

Beware: chemicals found in many cleaning substances are dangerous to have so close to your eyes and can ruin your lenses. You should only use an optical lens spray or cloth specifically made for eyeglasses.

When searching on the internet, most sources show how to use dish soap when cleaning eyewear lenses. However, if you’re glasses have special lens coatings like anti-reflective, UV protection, or blue light blocker, this is a big no!

Having any of these coatings and then using dish soap will, over time, strip and break down the lens coating. By striping coatings off, the lenses are more subjectable to other forms of damage.
