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.
Warning: Wax can haze coated lenses or interfere with anti-reflective properties. Not recommended for daily-wear prescription glasses—maybe okay for sunglasses or old readers.
4. Brasso or Metal Polish? Think Twice!
You might see online hacks suggesting Brasso (a metal polish) for lens scratches. Do not use this on eyeglasses. It’s far too abrasive and will permanently cloud or etch your lenses.
5. Prevention > Repair: Protect Your Lenses Going Forward 
Since true scratch “repair” isn’t really possible, focus on prevention:
Always store glasses in a hard case
Clean with lens cleaner + microfiber cloth (never paper towels or shirts!)
Set them down lens-up
Consider a scratch-resistant coating when ordering new lenses
Keep a backup pair for rough days
When to See Your Optician
If scratches are:
In your direct line of sight
Causing eye strain, headaches, or glare at night
Paired with peeling coating or cracks
…it’s time for a replacement. Many vision plans cover annual lens updates, and clear vision is worth the investment.
Dry with a clean microfiber cloth.
Final Thought
Your glasses are more than accessories—they’re your window to the world. While a baking soda paste might soften a tiny nick on an old pair of readers, never risk damaging your primary prescription lenses with DIY fixes.
Sometimes, the kindest thing you can do for your eyes is to let go of the scratch—and get a clear view again.
