A number of months ago, my eyeglasses fell onto a washroom tile. Now, due to the impact, some tile color which is white got onto my eyeglasses on the right lens. Some of the color came off. However, I want to get all of the tile color off. Palmolive dish soap is the only dish soap I have on hand to use and the eyeglasses cleaning solution did not make a difference. The lens are transition lens with scratch prevention coating on them. How to effectively remove the scratch-free lenses tile color from the lens without scratching the lens?
My home has soft water. That comes from a deep well. So, the water is softer than city tap water. Also, my eyeglasses are less than 2 years old. The color marks are not scratch marks because the tile color has faded in areas of the tiles over time. In the past, any fall of my eyeglasses if ever my eyeglasses fall onto the floor has never made a scratch on them. Thus, a scratch can be ruled out since most of the tile color came off upon washing my eyeglasses right after they fell onto the tile.
