Quality sunglasses come with nice case. Lightweight, comfortable, well made - they do run small, so they are a great size for most women and fit me perfectly! I didn't find them to be child size, but if you normally purchase men's sunglasses these would not be right for you.

    these light weight glasses have quality lenses and frame as described. The temple to temple distance is 5' so it definitely wont fit wide face. Polarization works very well. However, it looks like I got a defect one- left lens distortion. I felt big headache in my left head after wearing this glass, and sore left eye. seems like it has a different focal.

    Crisp clear lenses even when they look smudged. So light and I never get that sunglasses headache from them pushing behind my ear. I bought a second pair for when I inevitably scratch these beyond wear. My friend has a pair of Maui Jim's that are a few years old and I couldn't believe that these felt lighter. The two were incredibly similar in design and these are a much better price.

    I have always worn Costa sunglasses but have never had anything like these. The brown lense is PERFECT for driving. The glasses are so light it is as if they are not there, yet they still feel sturdy. I would pay retail for these so with this deal it cannot be beat.

    I havent worn sunglasses in years as I could never find a pair that was comfortable for longer than 20 minutes. I have a hard time wearing sunglasses as they hurt the tops of my ears or the bridge of my nose was bothered but these are so lightweight and comfortable, I can wear them for long periods of time without irritation. I have even played tennis with them on and they didn't bother me when I was sweating. I would highly recommend these for anyone who wishes they could just find a comfortable pair of sunglasses. No more squinting for me, finally!

    The Description is spot on as far as so comfortable you don't realize they are on. However the lenses so far are prone to fog up quite often. They look great and feel great, but honestly the fogging part is a little annoying. Hopefully this is just a possible summer humidity issue???
