10 things your eyes can tell you about your health

Eyes aren't just the window to your soul — they also offer a glimpse into your health. Changes in your eyes can signal vision problems, diabetes, stress or even retinal detachment. What's more, most of these you can actually see for yourself — assuming you know what to look for. Compiled from Woman’s Day, Natasha Herz, the clinical spokesperson for the American Academy of Ophthalmology, reveals what your eyes say about your health, and how you know it's time to visit your doctor.

You could have an infection

Do you wear contact lenses instead of glasses? Watch out for white spots on your cornea. This is quite common among people who wear contact lenses, says Herz, and can be a sign of a corneal infection.

You're too stressed

Stress can manifest in many ways, one of which is an eye twitch. It's more annoying than concerning, but it can be a sign you need to get some more rest and manage your stress levels a bit more, Herz adds.



You could have diabetes

Blurred vision usually means you need glasses — but you should have your eyes checked no matter what. Not only can blurred vision signal a medical problem with the eye itself, but it can also be a sign of a more serious illness like diabetes. Even without trouble seeing, your ophthalmologist may be able to detect diabetes during an eye exam based on irregularities in your retina.

Your cholesterol is too high

If you notice a white ring forming around your corneal arcus, it might be time to visit your ophthalmologist as well as your general physician for a check-up. While this particular colour change is most commonly a sign of ageing, Herz states it can also be an indication of high cholesterol and triglycerides — which might mean an increased risk of heart attack or stroke.

Your blood pressure is too high

In addition to upping your risk for heart disease and strokes, untreated high blood pressure can also damage the blood vessels in your retina, known as hypertensive retinopathy. You can't see the effects in the mirror, but your doctor will be able to spot the damage during your eye exam — even more reason to stick to your annual screenings, considering tipping you off to high blood pressure could actually save your life.



You have allergies

If your eyes are super dry and the skin around them is looking a little worn, you might be unconsciously rubbing your eyes too often. "Rubbing your eye hard or often can cause your eyelid to become looser, more relaxed and even saggy," Herz warns. "If the eyelid sags away from eye, it not only causes wrinkles, but also allows increased exposure to air and can make the eye become overly dry." One of the most common culprits of itchy eyes: seasonal allergies.

Your retina could be in danger

You know those little specks that move around your field of vision sometimes? They're called eye floaters and, while they're relatively common, they also shouldn't be dismissed. Herz warns that a sudden increase in the number of floaters you see could be a sign of a retinal tear or detachment. Yikes!

You're straining your eyes

Broken blood vessels may look alarming, but for the most part they're simply an indication that your eyes are working overtime. "It most likely is caused by coughing or straining," Herz explains. "Even though it looks blood-red and terrible, it is harmless and not indicative of any eye disease."



You're getting too much sun

Some people develop a yellowish patch or bump on the whites to the side of their iris, called a pinguecula. "A small percentage of these are pre-cancerous, but usually they are not," Herz says.

What causes them? "They are most often seen in people who spend a lot of time in the sun and are similar to a callus on the skin," she adds. However, wearing specific lenses may protect your peepers from sun damage, so talk to your ophthalmologist if you start seeing the patches.

You could have jaundice

If the whites of your eyes are yellowing like old paper, it should come as no surprise that this is definitely a warning sign something is wrong in your body. The biggest contenders for culprit? Jaundice, a condition that occurs when there's too much bilirubin — a yellow compound formed from the breakdown of red blood cells — in your blood. It’s pretty rare in adults but much of the time it's due to an infection such as hepatitis, alcohol-related liver disease, or something blocking your bile ducts such as gallstones or cancer.
