They say the eyes are the window to the soul, but are they also a window into your risk of getting certain medical conditions? Possibly. Here are three conditions that you may be surprised to learn are linked to eye shape and color.
If you love to crank "Brown Eyed Girl" by Van Morrison, rejoice — if your peepers are the right color. Various studies have shown that when exposed to a loud environment, brown-eyed people have less hearing loss than those with blue eyes, WebMD reports. Brown-eyed people have more melanin — the pigment that provides the color of skin, hair and eyes — in their eyes and ears. The extra melanin could give them a bit more protection when noise levels are high.
Blue-eyed people are more likely to drink alcohol and might have a higher risk of becoming addicted, according to a 2015 study published in the American Journal of Medical Genetics: Neuropsychiatric Genetics (Part B). Researchers found that those with light-colored eyes had a higher incidence of alcohol dependency than those with dark-brown eyes, and the strongest tendency was among blue-eyed individuals.
Stroke risk and problems with nervous system
The condition known as anisocoria occurs when a person has pupils of different sizes, according to the American Academy of Ophthalmology. Many people have different-sized pupils without any health repercussions; however, this condition can be a symptom of serious health issues with the nervous system, as well as affect your risk of stroke and viral infections.
