Dark eyes: Less likely to have macular degeneration
Your eye color meaning can give insight into your overall eye health. “A dark iris blocks more ultraviolet light,” says Christopher Quinn, OD, the president of Omni Eye Services in Iselin, NJ, and the secretary-treasurer of the American Optometric Association. “UV light is a risk factor for macular degeneration. Extra light that gets into the eyes of people with light-colored irises may cause them to have more retinal degeneration.”
Dark eyes: Lower melanoma risk
Dark-colored irises might indicate you have a lower risk of skin cancer. In a study published in Cancer Epidemiology, Biomarkers & Prevention, researchers took DNA samples and gathered sun exposure data from nearly 500 white children, ages 6 to 10, for four years. Children with the blue-eye gene were more likely to develop moles compared to children without the gene. (The number of moles people develop during childhood can predict the risk of melanoma in adulthood.) Other research has found that people with blue or green eyes are at greater risk of melanomas of the eye, likely because they have less light-absorbing pigment to shield the eyes from sun damage. But no matter what your eye color meaning may infer, it’s always a good idea to protect your eyes with large sunglasses or UV-absorbent contact lenses, says Quinn. Here are 6 diseases that eye doctors find first.
