Buffing Scratches out of Polycarbonate Eyeglass Lenses

I've read most of the suggestions, but here is what worked for me. I got my polycarbonate lenses with the AR coating at Walmart. As most of the tips suggest, the most likely cause of your scratches are due to scratches in the AR coating. Deciding I could live without the coating, I went whole hog and attacked the problem with gusto!


I have a Dremel tool with a polishing disk. I had some Mcguires cleaner/wax which I assumed had a small amount of abrasive as part of the "cleaner" part of the formula.

I cleaned the lenses with dish soap and water several times and dried them with a clean cotton cloth. Next I rubbed a liberal coat of the wax on the lenses with my clean finger tip. Set the dremel tool to a medium speed and began to buff the lenses with a circular pattern. The scratched area cleaned right up and I could tell it was the AR coating that was the problem. Once the scratches were gone, I just continued to buff the lenses, applying more wax as I went until I could tell all of the coating was gone. Presto, no more scratches and I actually liked the lenses without the coating better!

DON'T DO THIS. Ok, if you insist. DO NOT USE THE EDGE OF THE BUFFING WHEEL. It will eat right through your polycarbonate lens. Use the wheel on the flat face and as much of the face as you can without touching the metal part to the glasses and PATIENCE.


Go slow. Test on the upper outside edge of the glasses so if you screw up, you can bale and still be able to wear the glasses. I know. I've tried this and destroyed the lens.
