The first thing to note is that I got the gunmetal finish and they are much more gray than the picture. But the measurements in the details are actually spot on when measuring from the hinge. For the price and the interesting shape I'd say that these are very much worth it. I've been wearing them for the past two weeks with no issues whatsoever. Also, I got the advanced lenses which have the blue light filter, I can't tell if it helps that much but they do have a cool purple sheen to them when light reflects off them.

Solidly built, I got it because it was supposed to fit larger people and for the most part it fit my face well. i'm really happy with my first purchase here.

Great frames, stylish, good quality, metal frame and still light weight, i´ve been a costumer for some years now and are one of the best frames they´ve released, at least for my style and head shape. Like them so much that i bought the gold one and made it into sunglasses.
