  • This was a great question, and great answer...  thanx for your input guys <3

  • What an intriguing question!   I googled for related articles and found that if you have very little pigment in your iris, your eyes will appear blue or light grey.   If you have no pigment at all like people with albinism, your eyes will appear pink due to blood vessels in the back of the eyes reflecting light.   I am guessing that even if someone loses all the pigment in the irises, it would not cause blindness, rather, this person's eyes would be more sensitive to light and UV damage just like the white spots on our skin.
    • great question and great answer
