What do your eyes reveal about your health?
Your eyes aren't just windows to your soul—they're also a window into your health. Changes in your eyes can signal vision problems, diabetes, stress, and even retinal detachment.
What’s more, most of you can actually see these signs yourself if you know what to look for. Here are some health issues you can ask your eyes about.
Infection
If you wear contact lenses instead of glasses, keep an eye out for white spots on your cornea (the clear, white layer at the front of your eye). These white spots are common in contact lens wearers and can be a sign of a corneal infection.
Stress
Stress can manifest itself in many ways, one of which is eye twitching. This condition is more annoying than worrying, but it can be a sign that you need to get more rest and manage your stress levels a little more.
Diabetes
Blurry vision usually means you need glasses – but you should get your eyes checked no matter what the problem is. Blurry vision can be a sign of eye disease (like cataracts or macular degeneration), but it can also be a sign of a more serious condition like diabetes.
In fact, an August 2014 study found that 73% of people with diabetes reported blurred vision. Even if you don't have any vision problems, your ophthalmologist can detect diabetes during an eye exam based on abnormalities in the retina.
High cholesterol
If you notice a white ring forming around the black part of your eye (medically known as the iris), it may be time to get it checked out by your ophthalmologist or general practitioner. While this particular color change is often a sign of aging, it can also be a sign of high cholesterol and triglycerides – which can increase your risk of heart attack or stroke.
High blood pressure
In addition to increasing your risk of heart disease and stroke, untreated high blood pressure can also damage the blood vessels in your retina, a condition called hypertensive retinopathy. You can't see the effects in a mirror, but your doctor can spot this damage during an eye exam—yet another reason to get your blood pressure checked every year, because treating high blood pressure early can literally save your life.
Allergy
If your eyes are very dry and the skin around them feels a little scratchy, you may be rubbing your eyes too often. Rubbing your eyes vigorously or frequently can cause your eyelids to become loose, droopy, and even saggy.
If your eyelids droop, it not only causes wrinkles, but it also increases your eye's exposure to air and makes your eyes too dry. One of the most common culprits for itchy eyes is seasonal allergies.
Retinal disease
Do you see dark spots that occasionally move across your eyes? These are called floaters, and while they are common, they should not be ignored. A sudden increase in the number of floaters you see could be a sign of a retinal tear or detachment.
Lack of sleep
If you notice puffy, red eyes, don't assume you have an eye infection. It could just be a sign that you're tired. In addition to eye twitching, lack of sleep can cause irritated, red eyes.
Too much sun exposure
Some people develop a pale yellow patch or bulge on the white of their eye next to the iris, called a pinguecula. A small percentage of these are precancerous, but usually they are not.
The cause? They're most commonly seen in people who get a lot of sun exposure and resemble scar tissue on the skin. But a December 2013 study looked at the effects of UV light on the eyes and found that wearing special sunglasses can protect your eyes from sun damage, so talk to your eye doctor if you start to see them.
Jaundice
If the whites of your eyes are yellow like old paper, then it is definitely a warning sign that something is wrong in your body.
The prime suspects? Jaundice, a condition that occurs when there is too much bilirubin—a yellow substance formed from the breakdown of red blood cells—in the blood. If the liver fails to filter the cells, bilirubin builds up and can cause the eyes and skin to turn yellow. The condition is rare in adults (some babies are born with jaundice), but is most often caused by infections like hepatitis, alcoholic liver disease, or bile duct obstructions like gallstones or cancer.
Sitting at the computer too much
Too much computer use can cause eye strain and watery eyes. Ironically, watery eyes are a symptom of dry eyes, which is the eye's way of trying to compensate for dryness. This is common in people who spend a lot of time looking at a computer or TV screen.
Eye strain
Broken blood vessels can look scary, but most of the time they're simply a sign that your eyes are working too hard. The most common cause is coughing or straining. While they're red and creepy, they're harmless and not a sign of eye disease."
