For the last 41 years I've been color blind. As a kid, I colored in things wrong and failed (to everyone's amazement) those tests where you have to pick out a number or letter from a circle filled with colored dots. As an adult, I've made fashion faux pas, mixing the wrong colors so many times that my wife now checks to make sure I'm not a walking eyesore of color.
Anyway, I recently got a new pair of sunglasses: a polarized pair of Oakley Hijinx. These replace a pair of Arnett Hot Cakes that I've had for over 10 years. After all that time, my wife and daughter convinced me that they looked silly; I looked as if I was a fly or maybe wearing goggles.
The polarization in these new glasses is incredible. I can see colors! At first it was a bit overwhelming. Everything just jumped out at me. Yellows were too bright. I'd get mesmerized by the different shades of green in a tree. I could tell the difference (for the first time) between the amber and red lights on street light. (I used to gauge the light's color by its position.)
I took an online color blindness test just to confirm that the glasses were helping. I scored 3 of 10 without the sunglasses., 6 of 10 with. I think I might have done better without taking the test on a computer: with the glasses on, I can barely see the screen.
