To get blinded as you drive to work it seems. I love how a majority of my fellow traffic comrades believe in the sun-visor and squint all the way to work method. As if we don't have enough traffic accidents with bad driving, but now add blind drivers to that mix. It's times like this I doubt Darwin and his theory of evolution. Thank God for Ray-Bans.
