I have a pretty bad case of photophobia and I was convinced by a sales person in a sunglasses sales place to purchase these when my old pair of cheaper sunglasses broke early this summer. I was hesitant since they weren't super dark in tint, etc. I tried them on and they actually looked good which surprised me because of the sporty style and more importantly, the polarized lenses blocked out the fluorescents in the store really well. I knew if they blocked those well, they would do well outside. They have. Unfortunately my first pair were lost when I handed my bag to someone (which will never happen again :) ) and so I had to re-purchase these again. I naturally wanted to purchase the awesome pair of sunglasses that have served me so well for so months and during the summer when the sun is at it's worst here in Texas. I highly recommend these glasses, especially if you have major issues with light! They are great for driving as well.
