You know, as far as mindless technologization goes, this is squarely in the category of products like Vessyl, but this is the first time I feel like it's actually done somewhat right.<p>It's unobtrusive, and unless you actually leave them somewhere, they're unrecognizable from ordinary sunglasses. My only concern was being pestered about "forgetting" my sunglasses when I leave home into a rainy, overcast day, but they seem to have taken care of that too. The range display feature is just a cherry on top, I'd kill for something like that when I'm trying to find something.<p>I like this!
