Scratched glasses are frustrating, but it’s important to know the truth: most scratches cannot truly be removed—only minimized. Many DIY methods work by lightly polishing or filling the scratch, which can reduce its appearance but may also damage lens coatings.
One common method is a baking soda paste. Mix 1–2 teaspoons of baking soda with a few drops of distilled water to form a thin (not gritty) paste. After cleaning and drying your lenses, gently rub the paste over the scratch in small circular motions for about 10–15 seconds. Rinse thoroughly and dry with a microfiber cloth. This may help with hairline scratches on uncoated plastic or glass lenses. Avoid this method if your lenses have anti-glare, blue-light, or scratch-resistant coatings, as it can remove them.
Plain, non-gel, non-whitening toothpaste is another popular suggestion. Apply a pea-sized amount to a damp microfiber cloth and gently rub the scratch for no more than 10 seconds. Rinse and dry. However, most modern toothpastes contain abrasive ingredients that can worsen damage, so this should only be tried on old or backup glasses.
Car wax or lens scratch fillers can temporarily reduce visibility by filling fine scratches. These products don’t remove scratches but may reduce glare. They’re not ideal for everyday prescription lenses.
Avoid harsh products like metal polish—they can permanently cloud your lenses.
If scratches are in your direct line of sight, causing glare, headaches, or peeling coatings, it’s best to see an optician. Often, replacement lenses are the safest solution.
Prevention matters most: use microfiber cloths, store glasses in a hard case, and never clean lenses with paper towels or clothing. Clear vision is worth protecting.
