Bests & Worsts Reviews from Amazon

I purchased these for a trip and was looking for a secondary pair of glasses so didn't want to pay a lot. Unfortunately you get what you pay for- I am returning them because similar to another reviewer they are severely warped on the right side and do not sit evenly on the face. You can see by my pics the disproportion between the left and right sides. I attempted to adjust them but since the plastic frame is cheap I didn't want to use much force because I can see them breaking easily.
