Scratches on lenses, don’t waste money: apply a little and they will disappear immediately

Choose the Right Toothpaste: Opt for a plain, white toothpaste without any added micro-beads or aggressive chemicals. Gel-based or whitening toothpastes should be avoided as they can be too abrasive for delicate lenses.
Apply the Toothpaste: Squeeze a small amount of toothpaste onto both lenses. Using a cotton pad, cotton ball, or even your finger, gently massage the toothpaste across the entire surface of the lens. Make sure to cover all scratched areas thoroughly.
Let It Sit: Allow the toothpaste to sit on the lenses for about 10 minutes. This will give the paste enough time to start working on the surface scratches.
Rinse in Warm Water: After 10 minutes, immerse your glasses in a bowl of warm water. Continue to gently rub the lenses while rinsing to help remove the toothpaste. Make sure all of the toothpaste is thoroughly rinsed off to avoid leaving any residue.
Dry Your Glasses: Once your lenses are clean, dry them using a soft, lint-free cloth designed for glasses. If available, use a microfiber cloth to avoid introducing new scratches. You can also use a hairdryer on a low, cool setting to help dry them.
Inspect the Lenses: After drying, examine the lenses. You should notice that the scratches have significantly faded or disappeared altogether, and your lenses should look clearer.
An Alternative Method: Baking Soda
If you’re looking for another natural solution, baking soda is a great alternative to toothpaste for removing scratches from lenses. Baking soda’s mild abrasiveness helps to gently buff out scratches without damaging the lenses.

Here’s how you can use baking soda to remove scratches:

Prepare a Baking Soda Paste: Mix a small amount of baking soda with water to create a thick paste. The ratio should be about 1 tablespoon of baking soda to 1 tablespoon of water.
Apply the Paste to the Lenses: Using a soft cloth or cotton ball, apply the baking soda paste to the lenses, gently rubbing it in circular motions over the scratched areas.
Let It Sit: Allow the baking soda paste to sit on the lenses for around 10 minutes, just like with the toothpaste method.
Rinse and Dry: Rinse your glasses in warm water, making sure all of the baking soda paste is completely removed. Dry the lenses with a microfiber or soft cloth, and check the results.
