I love my blublocker sunglasses, really I do; they make driving in the hills and on the freeways an absolute joy. But when I drive in the cities I have to put them aside and don my trusty raybans. Why? Because I’m red and green colour-blind, that’s why! The blocked-out blue makes it harder sometimes to see the green traffic lights (although I have no problem seeing the red lights!)
I had a great tweet from some blublockers retailers:
Cool – thanks, guys and girls!
