Interesting Eye Color and Health Factoids

As a society, we romanticize eyes as the windows of the soul but scientists now also recognize that the eyes are also a window to health. It must be said, nonetheless, that there’s no current science that can accurately predict health outcomes based on eye color alone.

On that cautionary note, you will find these factoids about eye color and health to be interesting. Just avoid blaming yourself for your eye color since it’s hereditary although you can temporarily change it by wearing prescription contact lenses from Target.

Color of Your Eyes

Numerous studies have shown the relationship between health and eye color including these interesting ones.  

  • Brown eyes

In a small study conducted at the University of Louisville, researchers discovered that brown-eyed people have slightly better reaction times in certain athletic activities in comparison with light-eyed people. But keep in mind that we shouldn’t discriminate against light-eyed people in athletic activities since performance cannot be based on eye color alone.

  • Green, blue and gray eyes

People with lighter-colored eyes generally have higher risks for cancer. This is because lighter eyes have lesser amounts of pigments necessary in protecting them from the sun’s harmful ultraviolet rays.

Indeed, studies have shown that light-eyed people have higher risks for melanoma of the uvea in comparison with their dark-eyed peers. Melanoma of the uvea, an extremely rare cancer affecting just six in a million adults in the United States every year, is a type of cancer involving the iris, choroid, or ciliary body.

  • Blue eyes

People with lighter-colored eyes, such as blue eyes, tend to be more sensitive to light. This is likely because of the sparse number of light-absorbing pigments in the iris – the more pigment, the lesser amount of light that can get through the iris.

Eye Conditions for All Eye Colors

Regardless of your eye color, you should be vigilant about your eyes’ health including looking out for symptoms that require immediate medical attention. A few of these symptoms include:

  • Red whites wherein the whites of your eyes start to turn red in color, a red flag for adults and kids alike. This is because redness is a sign of allergies, infection, or dryness, which should be looked at by an ophthalmologist.  
  • Yellow whites are usually the first observable sign of a liver impairment. Immediate medical consultation is a must.  

You should also seek your doctor’s opinion in case of blurred vision, hazy pupils, and white corneal ring, among others. Better yet, you should have regular eye health check-ups, preferably once or twice a year.
