These  copper lensed frames fit over my Rx glasses nicely. Not too big, not too small.
The warmer copper tint allows good vision and clarity wth UV protection for my recently diagnosed Macular Degeneration. I bought two pair and use them outside all the time. Thanks!
  After using these over the months, I still like them, but they are of different sizes, so one pair fits over my Rx glasses, and the other one doesn't.  I now have to make sure I bring the right pair for going on errands that demand I can read, and when I can just wear the smaller pair when working outside, etc.
