Not kidding and maybe... I might have some links buried here someplace that have that info adjunct to the main topic. I thought it was common knowledge - I believe that there is a huge body of statistical evidence on the subject but it's not a current topic of investigation as far as I know. Generalizing, the data runs from "worst" night vision at eye color blue to "best" at eye color brown. Just hearsay from me until I or someone else posts a link or two, I realize.

I don't recall reading or hearing any information on WHY - just that it is, and my own observations thru life have matched the "common knowledge".

I "can't see it" from a blue-eyed perspective, but I am certain that I can teach almost any unskilled but willing person to greatly improve their use of whatever inate night vision capability they have. Not really any secrets - before the widespread use of light amplification devices all military forces (certainly the US Army) devoted time to teaching recruits how to function effectively after dark.

What I'm geting at is that in most people I have helped "see", I can usually get a blue eyed person to see a little more effectively than an untrained brown eyed person. But not 100% - some folks just cannot see worth a hoot in low level light no matter what. In my experiences so far, all of those I've encountered were blue eyed.

There really are techniques to using the ol MK I night vision eyeballs that usually greatly improve one's ability and I suspect that most of us modern civillized folks won't stumble on them by accident - someone needs to show us.

Hope someone beats me to the punch and digs up some definite links with the info <grumble> I'd rather move on to other discussions <img src="/images/graemlins/tongue.gif" alt="" />
