I think she was saying that she couldn't use large frames, not that she had to. The smaller the frame, the lighter the glasses (and the thinner the lenses)! On the other hand, I also can't wear wire-rimmed or semi-rimless either. They look terrible due to the lens size...and I'd never find them if I took them off.

I can't use large frames either. They turn out to be coke bottles on the edges, even with high index lenses. The last pair of glasses I had took forever because the lenses are pretty much too fat for the frames at the corners and they were trying to force them to fit (the outer corner of the lens on my bad eye is close to 1/4 inch thick on that pair)
