Hi Audrey:
As far as I know, there is no direct correlation between eye color
and your refractive status of eye (whether you are nearsighted,
farsighted, or neither). People with any eye color can have any vision
disorder as well as be succeptible to eye disease. They can also be
correctable with glasses, contacts, and refractive surgery to see as well
as anybody with "normal" vision.
The darker your eyes (color of eye comes from amount of pigment in
the iris) however, the more pigment you have in the eye that can
potentially cause certain eye diseases. Some races have a higher
proportion of darker eyes and also have a higher incidence of certain eye
diseases. And people with lighter eyes can also be more predisposed to
acquire other types of eye diseases.
It is thought that the more pigment you have in your iris (thus a
darker eye), the more protection you have to the internal structures of
your eye by serving as protection against UV light. This can provide
protection against certain eye diseases to those people with more than
average sunlight exposure.
I hope this helps and good luck!
