[net.med] An explanation for polychromatic eyes

rsk@pucc-j (Wombat) (01/29/86)

Does anyone out there know what mechanism causes some folks to have
polychromatic eyes?  By that term, I mean eyes that change color depending
on things like the time of day, external light conditions, or mood; I do
not mean eyes which display multiple shades of color constantly.

I myself have such eyes; they vary through green, hazel, blue, and gray
depending on how I'm feeling and whether its sunny or cloudy, day or night.
[It's sort of like having a couple of mood rings on your face.]  I would
guess that this characteristic is inheirited through a recessive gene,
but I do not know whether any of my (genetic) relatives have this trait.

Please mail responses to me, and I will be happy to summarize.  Thanks.
