Today I was cleaning my mesa orange frogskins and a scratch appeared (clean Oakley authentic cloth/bag), the other day the same happened to my new Prizm custom Turbines but that time I was using the Oakley cleaning fluid. And one time in my car I accidentally touched the review mirror with the lenses while looking for something and guess what... a scratch! I feel like I have to be extra carefullwhile using my favorite Oakleys. Are some models or type of lenses more resistant than others? Is there a real way to remove small/shallow scratches?
