If it weren't for *one* serious defect, these would be my all-time favorite sunglasses. I've bought no less than 5 of these sunglasses over the last several years, and keep a pair in all of my vehicles, etc. I love them, almost.
The problem is that every single pair has developed scratches on the inside (none at all on the outside). I wondered for a long time how this could be - I even bought microfiber bags and swore to only store them in nice bags. Still they scratched.
It took me forever to realize that the scratches perfectly line up with the arms of the sunglasses. When you fold the glasses up, the tips of the arms touch the insides of the lenses in the middle. Over time, the arms eventually leave a significant number of light scratches in the middle of the lenses (see photos - all five pairs I own look like this).
Bottom line - if you ever keep your sunglasses in your pocket, even if you keep them in a soft pouch, expect them to eventually be ruined.
Flying Fisherman - Please change the design to make the tips of the arms softer than the inside of the lenses. I'd pay 2x as much for this one simple change - and then these would last forever!
Edit: I'm adding another star because these really are inexpensive. After a bit of testing, I've decided that standard heat-shrink tubing seems to be softer than the arms and doesn't scratch the lenses as easily. I'm going to buy another pair and heat-shrink the ends of the arms to see if I end up with less scratching. Still, I'm annoyed.
Flexible wrap around sunglasses are super comfortable and lightweight, with full wrap around, semi-rimless styling and non-slip nose and temple pads.
