A Boy in some part of china that I can not spell was born with blue eyes just like westerners. His parents were a little surprised, but as he grew older he never complained about it bothering him, and his vision seemed fine, so they simply ignored it. As time went on the child exhibited strange behaviors , such as squinting in full sunlight during recess at school, and his friends reported his eyes shining as would a cat when you shine light on them at night.
Eventually the child was asked if he could see in the dark and after he said he could his father took him out to catch crickets at night, the child did not even need a flash light. Soon news of this grew and an eye doctor came by and looked at his eye, in amazement he set up a test where the child had to perform tasks in almost total darkness.
So, check it out yourself, its a fun video, and makes you wonder what is in the soil or air in that part of china, as well as why the parents have not given the kid some dang sunglasses.
