Anyone who wears glasses will notice scratches gradually appearing on the lenses and affecting vision. With a little effort, you can completely cure these scratches. Depending on how badly your glasses are scratched, you may not have to spend money on a new pair of lenses.
Steps
Heal very small scratches

Apply liquid to the lenses. You can put the lenses in the water for about a minute, or use a specialized eyeglass cleaner. Regular glass cleaner is also very effective.
- Do not rush to use corrosive or highly acidic chemicals at this step (this will be introduced in the following example). Glasses usually have a protective layer over the lenses. Wiping or cleaning the lenses is essentially cleaning this protective outer layer. When curing scratches, you’ll be removing a small portion of the protective layer, but it’s best to remove as little as possible in the initial steps. [1] X Research Source

Find a soft, fine cloth specifically designed for glass cleaning. Use this cloth to clean your glasses. Note: Do not use rough fabrics to avoid losing the protective layer in this step.
- Using a fine cloth to wipe is essential because the microfiber texture of this fabric, if it creates new scratches, they are so small that they are invisible to the naked eye.
Use the cloth to wipe the lenses from side to side. Do not wipe in a swirling or circular motion, as this will swirl and collect on the lenses.
Treat more serious scratches with toothpaste
Put toothpaste on scratched glasses. Toothpaste contains micro-abrasive particles that are able to polish and wear down the protective layer.

Use a soft cloth to apply toothpaste evenly on the lenses. Be careful not to use rough fabrics as they will cause new scratches.
Rub the toothpaste on the lenses from side to side. You should also not rub in a circular motion to avoid leaving rub marks on the lenses.
- The abrasive in the toothpaste will be more abrasive to the lenses than if you just wiped it with a fine cloth. Rubbing toothpaste for too long in one place can cause the protective layer to penetrate and damage the inner lens layer.
Rinse off the toothpaste. You can use warm water or glass cleaner, or a combination of both.
Wipe again with a fine cloth. This step helps to remove all remaining fingerprints or toothpaste stains.
Repair extremely severe scratches with glass etching cream
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/7/71/Fix-Scratched-Glasses-Step-9-Version-2.jpg/v4-460px-Fix-Scratched-Glasses- Step-9-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/7/71/Fix-Scratched-Glasses-Step-9-Version-2.jpg/ v4-728px-Fix-Scratched-Glasses-Step-9-Version-2.jpg”,”smallWidth”:460,”smallHeight”:259,”bigWidth”:728,”bigHeight”:410,”licensing”:” <div class=”mw-parser-output”></div>”}
Buy the necessary materials. Usually when etching glass, people will use a relatively strong acid to engrave or burn an image on the glass. [2] X Research Source For the purpose of scratch treatment, this acid will be used to burn the protective outer layer on the lenses. You need the following materials:
- Glass etching cream. Armor Etch brand has many famous products, you can also choose products of many other brands.
- High quality rubber gloves for hand protection.
- Cotton swab or other tools to apply glass etching cream.
Use a cotton swab to apply etching cream to the lenses. Do not rub, but just lightly apply the cream to the surface. Because the acid in the glass etching cream is strong, you need to work quickly and only use enough cream to cover the entire lens.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/5/5f/Fix-Scratched-Glasses-Step-11-Version-2.jpg/v4-460px-Fix-Scratched-Glasses- Step-11-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/5/5f/Fix-Scratched-Glasses-Step-11-Version-2.jpg/ v4-728px-Fix-Scratched-Glasses-Step-11-Version-2.jpg”,”smallWidth”:460,”smallHeight”:259,”bigWidth”:728,”bigHeight”:410,”licensing”:” <div class=”mw-parser-output”></div>”}
Leave the etching cream on the lenses for no more than 5 minutes. Glass etching cream contains strong acids, so prolonged exposure will damage the lenses.
Rinse off the glass etching cream. You use water to wash if the instructions for use do not require washing with another substance. Rinse thoroughly to make sure no cream remains.
Wipe the glass with a smooth cloth. Use a soft cloth to wipe and dry the lenses in a horizontal motion.
Warning
- The above methods are applicable only to flexible plastic lenses with an outer protective layer. Today most glass has a protective layer, however older glasses cannot be repaired in this way.
- Either way, you should be careful. The price of a pair of glasses is quite expensive so make the right decision!
- Keep in mind that either way you can repair the scratch will remove a bit of the protective layer on the outside of the lens.
