Prescription eyeglasses are an essential item for many people with less than perfect eyesight. However, accidents and inattentiveness can sometimes cause scratches on the lenses of these glasses. These scratches can be distracting, detracting from the overall utility of the glasses. While scratches on glass lenses cannot be removed, scratches on plastic prescription eyeglasses can be buffed out, allowing you to extend their use.
Use a scratch repair product like Armour-Etch to buff out the scratch, applying small amounts and gently rubbing it in with a soft cloth.
Try a polisher--like Lemon Pledge or a nail polisher--to buff out the scratch. Apply small amounts and buff with a soft cloth.
Use toothpaste to abrasively rub out the scratches on the plastic lenses. Apply a small amount of toothpaste and buff with a soft cloth.
Apply hydrofluoric acid to the glasses in small amounts to burn out the scratches. Use only outdoors and with protective gloves.
Use these methods only with plastic lenses; glass lenses should be replaced if scratched.
