When i first saw theses glasses, I was amazed at the cheap price. I thought anything with that price tag has to be cheaply made. I was wrong. The glasses actually feel substantial and protect your eyes very well from the sun. However I do see that the glasses may not hold the test of time, just by looking them over and wearing them. But for the price, they'll be fun to wear until i can no longer do so. I suggest anyone buy a pair to use, they look good and have a great price. But not sure how well they will hold up throughout the seasons.
