These are actually insanely dark. If you live in the high desert, where it's sunny and snowy, they'd be great. They're too dark enough, however, that on a sunny day I still have some trouble seeing well in them, and I'm very light sensitive. It's not to the point they're dangerous when driving, but if you want to wear them doing some outdoor activity, you might have just enough trouble to be annoying, especially if you have to read or make out colors.

But hey, working TOO well isn't the worst problem to have, and they're good for driving. And the build quality is good. For the price, they're quite nice.
