How to Use It:
Mix 1–2 teaspoons of baking soda with a few drops of distilled water to form a thin paste (not gritty!).
Clean your lenses with lens cleaner or mild soap and water. Dry with a lint-free microfiber cloth.
Using a clean fingertip or soft cotton ball, gently rub the paste onto the scratch in small, circular motions for 10–15 seconds.
Rinse thoroughly with lukewarm water.
Dry with a clean microfiber cloth.
Best for: Hairline scratches on uncoated plastic or glass lenses.
Avoid if: Your lenses have anti-glare, anti-scratch, or blue-light coatings.
2. Non-Gel, Non-Whitening Toothpaste 
Some people swear by toothpaste—but only if it’s plain, non-abrasive, and fluoride-only (think: children’s toothpaste or basic white paste, not gel or “tartar control” formulas).
How to Use It:
Apply a pea-sized amount to a damp microfiber cloth.
Gently rub the scratch in tiny circles for 10 seconds max.
Rinse well and dry.
Dry with a clean microfiber cloth.
Caution: Most modern toothpastes contain silica or polishing agents that are too harsh for coated lenses. Use only as a last resort—and test on the edge first.
3. Car Wax or Lens-Specific Scratch Removers 
Yes, car wax (like Turtle Wax) has been used by some to “fill in” fine scratches—creating a smoother optical surface. There are also commercial lens scratch removers (e.g., Meguiar’s or specialized eyewear kits).
How It Works:
These products don’t remove scratches—they temporarily fill them with a clear polymer, reducing light scatter.
How to Use:
Clean lenses thoroughly.
Apply a tiny drop of product to a microfiber cloth.
Buff gently in circles.
Wipe off residue completely.
