These sunglasses are a great fit over my regular prescription glasses. They have zero lens distortion and the grey coloration of the lenses is even. Since the earpieces are solid and wide, they do make it a bit harder to see to the sides - I find myself turning my head farther than with my over-glasses sunglasses that have a small shaded &#34;window&#34; on the earpieces. The sunglasses are a bit large so require a large case to keep them from being scratched inside my purse. Happy with my purchase!
