These sunglasses are absolutely excellent.
They come in a range of very attractive colours - particularly the iridium lenses (something I've always been fond of). The glasses are also a very good fit; fitting snugly around the nose and also wrap around the sides of the eyes too - something that is very important when driving.
Perhaps the most impressive aspect of these glasses is the way in which they filter out sunlight; unlike cheaper sunglasses that simply make everything darker, these sunglasses only appear to block out the bright glare of the sun - leaving the rest of your view uninhibited.
The only reason that these glasses don't receive a fifth star is because the rubber on the arms of the glasses can leave your ears feeling sensitive after prolonged use if they aren't worn at the correct angle. But an absolutely fantastic purchase nonetheless.
