Everyone who wears glasses will eventually find scratches on their lenses that can impair the wearer's vision. Many of these can be fixed with relatively little effort. Depending on the severity of the scratches, you may be able to avoid costly new lenses.

Method 1 of 3:

Fixing Very Minor Scratches

  1. 1
    Apply liquid to the lenses. You can run the lenses under water for a minute, or you can use specialized cleaning solution designed for use with glasses.[1] Window cleaning sprays also work well.
    • Do not yet apply any chemical that contains abrasive materials or has a high acid content (as will be mentioned in later examples). Glasses typically have layers or coatings over the lens itself. As you are polishing or cleaning, you are really just wiping this exterior coating. When you remove scratches, you are buffing or removing a small amount of the exterior layers. It is best to keep this to a minimum in the initial phases of scratch removal.[2]
  2. 2
    Find a soft, microfiber cloth specifically designed for cleaning. You will use it to clean the lenses.[3] Do not use rough fabric. Though these may seem better designed to peel off layers of material, you really want to keep it to a minimum.
    • It is essential to use microfiber cloth because the incredibly small size of the fibers makes any new scratches or buffing marks so small that they are invisible to the naked eye.

  3. 3
    Use side-to-side wiping motions to go over the lenses with the cloth. Do not use swirling or circular motions, as these can create circular smudges on the exterior of the glasses.

Method 2
Method 2 of 3:

Fixing More Serious Scratches Using Toothpaste

  1. 1
    Apply toothpaste to the scratched lens.[4] Toothpaste contains microscopic abrasive particles that can polish and grind down the exterior layers.
  2. 2
    Use a piece of soft fabric to rub the toothpaste over the lens. Again, do not use any fabrics that are coarse or abrasive on their own; they will leave additional scratches in the lens.
  3. 3
    Rub the toothpaste over the lens using a side-to-side motion. Do not use circular motions as they can create circular scuff marks.
    • The abrasives in toothpaste are harsher than microfiber cloth alone. Concentrating on a single area for too long could penetrate the exterior layers and damage the interior lens.[5]
  4. 4
    Wash off the toothpaste. You can use warm water or glass cleaners, or a combination of the two.
  5. 5
    Perform a final cleaning with a microfiber cloth. Remove any remaining smudge marks from fingers or traces of residue from the toothpaste.

Method 3
Method 3 of 3:

Fixing Very Serious Scratches Using a Glass Etching Substance

  1. 1
    Purchase the necessary materials. Normally, glass etching involves the use a fairly powerful acid to cut or burn an image into glass.[6] In this particular context, it will be used to burn off the exterior layer of the glasses. You will need:
    • A glass etching substance. A brand known as Armor Etch produces one popular variety of the material, but there are others as well.[7]
    • High quality rubber gloves to protect your hands.
    • Cotton swabs or some other material to use for applying the substance to the glasses.
  2. 2
    Apply the glass etching substance using the cotton swabs. Do not rub the substance in, but merely apply it to the surface. Because of the strength of the acid in glass etching substances, you must work quickly. Only apply enough of the substance to cover the lens.
  3. 3
    Let the substance remain on the lenses for no more than 5 minutes. Again, etching solution contains powerful acids. Over-exposure to these acids will likely damage the lenses.
  4. 4
    Wash off the etching substance. Use water to wash off the etching substance, unless the instructions call for alternatives. Wash thoroughly to guarantee that no residue from the substance remains.
  5. 5
    Clean the glasses using a microfiber cloth. Use this to wipe and dry the lens, again using only side-to-side motions.

Warnings

  • The above methods should only be performed on plastic lens glasses that have coatings over the exterior. Most glasses currently produced fit those classifications, but older glasses cannot be fixed in such a way.

  • Whatever you do, be careful. Glasses are expensive, so use your best judgment.

  • Understand that any polishing will remove a bit of the protective exterior layer of material.

Article SummaryX

To fix scratched glasses, start by holding the lens under running water for 1 minute. Then, wipe it with a microfiber cloth using a side-to-side motion to prevent swirls and smudges. If that doesn't work, try buffing away the scratches by rubbing the lens with some toothpaste dabbed onto a microfiber cloth. Make sure to rub the lens for no more than 10 seconds using a side-to-side motion to avoid leaving additional scratches. Afterwards, wash off the toothpaste with warm water and remove any remaining residue with a clean, soft cloth.
