Normal
Can't go wrong with Costas. I had a pair when I was early 20s. Got stolen. Couldn't afford another pair till about 6 years ago when o realize the better the sunglasses the more protection. Had my current pair for 6 years. They are prescription and had to "upgrade" the prescription once. Now frames are starting to wear out. Will be in the market for a new pair soon. So comfortable I would rather where my sunglasses than regular glasses.
