The tint and polarization on these is great. However, they're missing a quality that I think is key to what makes this style of glasses: The lenses don't curve enough to cover your whole eye. This means there is a gap between the glasses and your head of a few millimeters where the sun can still shine into your eyes from the right angle. This is really annoying in the summer if you have to walk south, because the sun is at the perfect angle to come in from the side of the glasses.<br /><br />To summarize: staring straight at the sun: no problem. Walking around with the sun coming in from other angles? A little painful.
