In my opinion, you can put a pinch or two of baking soda into a small cup, then add a few drops of water, then mix the water and baking soda to form a thick paste, and using a lint-free cloth, apply the paste to the scratched lenses. Finally, rub the lenses with small circles until the scratch disappears.
I know a very easy way to deal with scratches! Just simply apply a small amount of non-abrasive toothpaste to some cotton wool and slowly buff away the scratch. Toothpaste is a quick and easy hack for minor scratches so if you have a deeper scratch, and you just need to repeat this process quite a few times.
As it is known that the car wax is another product to remove the annoying scratches, if you have scratches on your lenses and need a quick fix! The wax should be worked into your lenses and it will help to fill out and smooth over any marks.
