We can tell a lot about a person through their eyes—after all, William Shakespeare once stated they are the “windows to the soul.” We’ve exposed how you can detect if a person’s lying, in love, and more by looking at their eyes, but did you know that eye colors can tell the story of your own health? That’s right, scientists have been studying how eye color can reveal some things about your health condition. Keep reading to see what each eye color may indicate. We’ll discuss two different parts of the eye that can vary in color: the sclera and the iris. The sclera is the white part of your eyeball. The iris is the colored part of your eyeball, such as brown or green.
Our sclera should normally be white, but for some people, they turn yellow…or yellowish (think white with a yellow tint). This is usually due to jaundice, which means your liver is in some sort of trouble. This happens due to a build-up of bilirubin, which is typically cleared through the liver. But when it dysfunctions, the body is unable to rid itself of this substance. If you find your eyes turning yellow, it’s a good idea to make a doctor appointment to get a professional, medical opinion on the cause of the discoloration. Remember, medical issues are treated best when caught early.
Having a red sclera is much more common. In fact, we’ve all probably experience this at one time or another. It can be due to allergies, dirt or dust getting trapped in the eye, a wonky contact—the list goes on and on. In these cases, the redness is usually temporary. It’s often also easy to treat with eye drops or rinsing the eye with water to remove the irritant. But if you find that the redness is not going away despite typical treatments, it could mean something else is going on with your health. Persistent redness could be a sign of an autoimmune disease. It could also be a symptom of an eye infection. In either case, you’ll want to make a doctor appointment
The darker your eyes, the less likely you are to develop skin and eye cancers thanks to having more pigment to help protect them. While you still want to wear UV-protection sunglasses when outside, it’s not quite as dire as it is for people with lighter eyes. However, people with brown eyes are slightly more inclined to develop vitiligo. This is a condition where pigment disappears from patches of the body. One study, done at the University of Louisville, found that people with brown eyes have a tad better reaction time when playing sports or other athletic games.
Blue eyes range greatly in color, but tend to be pretty light overall. Due to this, people with blue eyes have a tendency to be more sensitive to light. This makes sense considering how we just discussed that brown eyed folk are less likely to develop skin and eye melanomas compared to lighter eyes. Blue eyes, make sure you invest in a good pair of sunglasses, and even consider throwing on a hat when you’re going to be outdoors.
Like blue eyes, green eyes need to be careful when out in the sun, as they have a greater chance of developing skin and eye cancers. Lighter eyes (this includes blue ones, too), also have a greater risk of developing age-related macular degeneration over time. This leads to vision loss or, in extreme cases, blindness.
