If you need sunglasses that fit over your regular glasses, look into "Fit Overs". They are comfortable, polarized, and don't make you look like 'Atomic Man", or like you've just had cataract surgery. I've had other "over the glasses" sunglasses, but they tended to drive me nuts after a while. "Fit Overs" do not. I can wear them all day, almost without knowing I've got them on.
