I have a few pairs of Oakleys that have these strange circles in the lenses. They are very faint, and look almost like a water stain but aren't. I thought they were scratches at first, but i have seen them on brand new lenses as well. Sometimes they seem to just suddenly appear, and unlike the cross hatch marks that another forum member mentioned, they don't only appear when the lens is wet, but all the time. It seems like every time i clean the lenses that have these marks, more appear, so at first i thought i was scratching them, but on most of my glasses, they are nowhere to be found. They do not affect vision, but they bug the crap out of me! Does anyone else have this problem? I would take a pic, but they don't show up.
