I should have known that my Transition lenses would not be a good buy when they were the only glasses in the store that did not come wtih a warranty. I was trying to save money and cut down on lost glasses, and buy one pair of Transitions instead of a pair of glasses and a pair of sunglasses. My eyes are very light-sensitive and I need to wear sunglasses to drive on most days, even if it is overcast. Well, the transitions were stylish, with a pretty blue frame to match my eyes, and they were very comfortable. I don't wear glasses all the time, only to drive, so I notice wearing them more than others might. For me, the lenses did not work great because they never got quite dark enough when I was in the bright sunlight. Also, they got a little bent when my son grabbed themoff my face. I gently tried to fix them and they broke in half. I was suprised that they broke so easily. I went back to wearing two pairs of glasses, since I was not happy with the durability of these glasses. Also, i like a brownish tint and these had a grayish tint, which I think made me look older than I am.
