I have two pairs of these, I love them so much! These are the first I found where I really like the fit. The lenses are very easily interchangable. I have had a problem finding sunglasses that are a good fit. these aren't too wide or big. There is just the right amount of space on the side and the overall coverage is perfect in my opinion. The grips on the side keep them on my head as well! Would definitely recommend these to anyone looking for a good pair of not too expensive sunglasses.
