I happened to scratch my Insta 360 One RS lenses, New, cost £279 so not really cheap. I had nothing to lose and tried to restore the lens using car headlight restoration compound. I know I have removed anti glare layer but there is nothing I could do about it. Better to have working lens than scratched and with anti glare. The results are amazing. I bet that if I put more time into that the results would be even better. Hope this helps someone.
