5 Ways to Fix Scratched Glasses at Home — What Really Works (And What to Expect)

Discovering a new scratch on your glasses can be frustrating. Whether you dropped them on the floor or accidentally placed them face-down on a table, that small mark can become a major distraction. Deep scratches can cause eye strain, unwanted glare, or blurry vision, since your eyes have to work harder to see around the damage.
While professional opticians often remind us that “lens scratches can’t truly be repaired,” there are some gentle ways to make minor marks less noticeable at home. Modern lenses often have coatings that are difficult to restore, but older or basic lenses may respond to these simple fixes.
Here are five ways to handle scratched lenses safely, along with tips for protecting your vision.
1. Baking Soda Buffing Method 🌿
Baking soda acts as a mild abrasive, which can help smooth tiny surface scratches on basic plastic or older glass lenses.
How to try it:
- Mix 1–2 teaspoons of baking soda with a few drops of water to form a thin paste.
- Wash your glasses with mild soap and dry with a microfiber cloth.
- Apply a small amount of the paste to the scratch and rub gently in a circular motion for 10–15 seconds.
- Rinse thoroughly with room-temperature water and dry with a soft cloth.
Best for: Very light scratches on lenses without special coatings.
Avoid if: Your lenses have anti-reflective or blue-light coatings.
2. Plain Toothpaste 🦷
Toothpaste can also act as a mild abrasive. Use extreme caution:
Steps:
- Choose plain, white, non-gel toothpaste. Avoid whitening or tartar-control formulas.
- Apply a tiny amount (¼ pea-size) to a damp cloth.
- Rub gently over the scratch for no more than 10 seconds.
- Rinse thoroughly.
Caution: Modern lenses may be too soft for toothpaste. Test a tiny edge first.
3. Filling Scratches with Wax 🚗
High-quality car wax or specialized lens wax kits don’t remove scratches, but they fill them so light passes through more smoothly.
Steps:
- Clean the lenses thoroughly.
- Apply a small amount of wax (less than 1/8 tsp) with a soft cloth.
- Buff lightly and remove excess until the lens looks clear.
Note: This is temporary and may smudge anti-glare coatings. Best for sunglasses or older lenses.
4. Avoid Metal Polishes ❌
Some online guides suggest metal polishes like Brasso. Avoid this! They are far too strong and can permanently damage lenses, causing fogginess or etching.
5. Prevention and Care 🛡️
Since repairing lenses fully is often impossible, preventing scratches is key:
- Use a Hard Case: Always store glasses in a protective case.
- Clean Properly: Use lens spray and a microfiber cloth. Avoid paper towels, napkins, or clothing.
- Lenses Up: Place frames on surfaces with lenses facing up.
- Upgrades: Consider premium scratch-resistant coatings for new lenses.
When to Replace Your Lenses
If scratches are in your line of sight or cause headaches, visit your eye doctor. Clear vision is worth the investment. Many vision plans allow lens replacements every year or two—check your benefits.
Final Thought
Glasses help you see the world clearly. Minor fixes like baking soda may help with old or spare pairs, but for deep scratches on your main lenses, replacement is safest. Protect your eyes and keep your vision sharp.
