From what I can recall the color of the eye has little if any effect on you ability to see at night. The correlation is dark eyed people happen to have more rods (light sensitive part) than light eyed people. Light eye people have more cones (color sensitive part) than Dark eyed people. In a nut shell Dark eyes usually indicates better night vision. Light eye indicates better color distinction. None of this is absolute there are light eyes with great night vision and dark eyes with great color distinction. And there are the super freaks with great eyes altogether. <img src="/images/graemlins/shocked.gif" alt="" />

P.S. Let me know if you have any questions or conflicting information.
