I very disappointed with these glasses.  The lenses are not scratched and I have taken veryood care of them, making sure that I put them in a case when not wearing them and inky cleaning them with a lens cloth, but the film on the inside of the classes has bubbled.  Its peeling right off.  I have never seen this happen with glasses, especially at this price point.  I do not recommend these.  I have another pair of sun clouds and those are in perfect shape after several years of wear.  Something is amiss with this pair.
