Do Not Throw Away Scratched Glasses

Scratched lenses make it hard to see and give you headaches. Before buying new glasses, try these 4 methods. They work on eyeglasses, sunglasses, and reading glasses. Important: these methods work best on glass lenses. Plastic lenses scratch easily and are harder to repair.

Method 1: Baking Soda Paste (Most Effective)

Mix 1 tablespoon baking soda with 1 tablespoon water to form a thick paste. Apply the paste to the scratched lens using a soft cloth. Rub gently in circular motions for 10-15 seconds. Rinse with water. Dry with a microfiber cloth. Repeat if necessary. Baking soda acts as a mild abrasive that buffs out scratches.

Method 2: Non-Gel Toothpaste (For Light Scratches)

Use white, non-gel toothpaste (not the gel kind with stripes). Apply a pea-sized amount to the scratched lens. Rub gently with a soft cloth in circular motions for 10-15 seconds. Rinse thoroughly. Dry with a microfiber cloth. Toothpaste contains mild abrasives similar to polishing compounds.

Method 3: Vehicle Glass Polish (For Deep Scratches)

Products like Cerium oxide or car glass polish work on deeper scratches. Apply a small amount to the lens. Use a felt cloth or buffing pad. Rub in circular motions for 30-60 seconds. Wipe clean. These products are designed for auto glass but work on eyewear.

Method 4: Brass or Silver Polish (For Glass Lenses Only)

Apply a small amount of brass or silver polish to a soft cloth. Rub onto the scratched lens in circular motions. Wipe off excess. Rinse with water. Dry with a microfiber cloth. Do not use on plastic lenses – they will cloud permanently.

What NOT to Do with Scratched Glasses

  • Do not use baking soda on plastic lenses (can cause clouding)
  • Do not use abrasive cleaners like Comet or Ajax (ruins lenses)
  • Do not use paper towels or tissues (scratch lenses further)
  • Do not use Windex or glass cleaners (strips anti-reflective coating)

How to Prevent Future Scratches

  • Store glasses in a hard case when not in use
  • Clean lenses with microfiber cloth only (not shirts, towels, tissues)
  • Use lens cleaning spray (or mild dish soap and water)
  • Avoid placing glasses lens-down on surfaces
  • Do not leave glasses in hot cars (heat weakens coatings)

When to Replace Glasses Instead

  • Anti-reflective coating is peeling (cannot be repaired)
  • Deep scratches across your line of sight
  • Plastic lenses with multiple deep scratches
  • Prescription has changed (new lenses anyway)

Conclusion: Baking Soda First, Then Toothpaste

Start with baking soda paste – it works for most scratches. If scratches remain, try toothpaste. For deep scratches on glass lenses, use car glass polish. Always use soft cloths and gentle pressure.
