[Request] How to remove scratches from glasses frames

CaptionI am currently in China, and have an annoying scratch on the inner portion of my glasses (on the bridge of the nose). It is quite painful due to rubbing/scratching and i have a sore mark and scar there now. I tried a bandaid but that is a temporary fix. How can i remove this annoying scratch permanently?P.S the glasses shops i have been to aren’t particularly in the helping mood, so i must go this route alone
