An Iowa fourth grader was born unable to see colors. A special pair of glasses has allowed colors into his world and the video capturing the moment is the most emotional thing you've seen this week.

Ten-year-old Cayson Irlbeck of Johnston, Iowa was born colorblind and had never seen the world in color. Then his parents found a California company named Enchroma, that makes special glasses that can act, as WREG-TV says, as "an optical assistance device." There was a 50 percent chance they'd work and did they ever. Grab a tissue or two when you watch his reaction to seeing colors for the first time... something so many of us take for granted.
