Without a doubt, Serengetti Sunglasses are the best optics on the planet. Vision is better in any light, even while driving at night to reduce glare. Only problem I have is that the tip of the temples will rub the coating off the lenses in one spot when folded. Eventually this causes an area that is a different "color" from the rest of the lens, and is a distraction. None the less, Serengettis are the ONLY sunglasses I will wear.
Pros: Superior sight in any light
Cons: Temples cause wear on lens when folded
