Apply toothpaste: Apply a small amount of toothpaste to both glasses. Using a cotton swab, a cotton swab, or even your finger, gently massage the toothpaste over the entire surface of the glass. Make sure to thoroughly cover all scratches.
Leave it on: Let the toothpaste sit on the glasses for about 10 minutes. This gives the toothpaste time to work on the scratched surfaces. Rinse with warm water: After 10 minutes, immerse the glasses in a basin of warm water. Continue to gently rub the glasses while rinsing to remove the toothpaste. Rinse thoroughly to avoid leaving residue.
Dry your glasses: Once your lenses are clean, dry them with a soft, lint-free cloth specifically designed for glasses. If you have one, use a microfiber cloth to prevent new scratches. You can also dry them with a hair dryer on low heat.
Inspect the lenses: After drying, inspect the lenses. You should notice that the scratches have significantly faded or disappeared completely, and the lenses should appear clearer.
Alternative method: baking soda
