So I've just recently purchased my very first pair of prescription eyeglasses. I decided to splurge and get the very best, and got a pair of the Oakley Bucket glasses. They're comfortable and work well, but the lenses are absolutely IMPOSSIBLE to get/keep clean. Are there any tips and/or tricks with these that might help? I haven't tried any lens cleaning solution as I cannot find the actual Oakley stuff, and don't want to risk damaging the lenses with any old off the shelf stuff. I've tried every microfiber cloth I own (including the little bag they came in) that is designed for delicate things like this, and while sometimes I can get pretty close to clean, there are still streaks in the lenses. In place of alcohol based solutions, I've tried distilled water, spring water, and tap water, all with similar results. Any tips? Thanks!
