There’s more to eye color than meets
the…eye. For one, contrary to what you may have learned in school,
there’s more than a single gene involved, which is why your specific
hazel hue can look so vastly different from your daughter’s, says Rachel
Bishop, MD, chief of the consult service section of the National Eye
Institute. Though as with skin pigmentation, she says, you’ll see eye
color similarities among families and ethnicities (dark eyes are more
prevalent in an African population than a Scandinavian one, for
example)
What’s more, whether they’re brown,
hazel, green, blue, gray, or somewhere in between, your eyes can tell
you more about yourself than you might expect—and not just in “the eyes
are the windows to the soul” kind of way. Your eye colour could dictate
your risk for certain diseases or even predict how your body handles
booze.
Dark-eyed people are more likely to have cataracts.
A fogginess appearing over the pupil of
the eye is a common sign of cataracts, a clouding of the vision common
with aging. And people with dark eyes are at greater risk: A 2000 study
published in the American Journal of Ophthalmology found that
dark-eyed people had a 1.5 to 2.5 times greater risk of cataracts.
Protecting your eyes from ultraviolet raysis one of the crucial steps of
cataract prevention for anyone, but the researchers recommend dark-eyed
sunbathers take particular caution. (Wearing sunnies and a hat with a
brim is a good place to start!)
People with dark eyes may be more sensitive to alcohol.
If your eyes are black or brown, you may
drink less than your blue- or green-eyed friends, according to a 2001
study published in Personality and Individual Differences.
