These are the first sunglasses I've bought that haven't been from a $10 or $20 rack at a store, thinking that I shouldn't spend more than that on sunglasses since they simply need to protect my eyes. But what I didn't realize until I bought these is that they are solid enough to stay in the one position you place them for hours. For cheaper ones, I'd have to consistently shift them around my face because they were uncomfortable, but not knowing any better, I thought that's just what sunglasses are. But no! Now I place them on my nose, and they stay there the entire time I'm wearing them. And that's when I realized it was time to embrace Le Specs!
