17 Things Your Eyes Can Tell You About Your Health

Our eyes are super sensitive, and they react to many processes in our bodies. Got allergies? Red eyes. Liver problems? Yellow eyes. By looking at your eyes, you could find out what’s going on inside your body. Let’s find out what your eyes say about your health. 

  1. Bulging Eyes

With bulging eyes, your eyes basically ‘swell’ up. This can be a symptom of an over-productive thyroid. It releases too many hormones, which can lead to bulging eyes, but also sudden weight loss, hand tremors, nervousness, diarrhea, and more symptoms. Over productive thyroids should be treated quickly, so don’t wait with going to the doctor.



  1. Blurred Vision

Abrupt loss of vision can be highly alarming because it can be related to a problem with blood flow to the brain or the eyes. This could lead to serious, permanent damage, so it would be best to seek medical attention as soon as possible if you ever experience something like this. 

  1. A Grey Ring Around the Cornea

A ring around the cornea could possibly be a warning sign. If you’re older than 40, you probably don’t have anything to worry about, but if you’re not, you should ask your doctor about it. The condition is called a corneal arcus and is caused by fat deposits that grow around the cornea. It could be a sign of extremely high cholesterol levels in your body. 



  1. Drooping Eyelids

Drooping eyelids could happen when you age, but they can also be a symptom of myasthenia gravis. This is when your immune system attacks your muscles, making them weak. There are solutions for it, like medications and filtering your blood (which is a temporary solution). In some cases, it needs to be surgically treated. 

  1. Yellow Eyes

If you have liver problems, your eyes can turn yellow. It’s caused by high levels if bilirubin, which is made by the liver. When your liver is inflamed or damaged, it makes too much bilirubin. 



  1. Eye Twitches

Many people have eye twitches, and they’re usually very harmless. You can get those twitches when you are stressed or very tired. But, in some (very rare) cases, they can be a signal of something serious like MS. In this case, you will probably also have other symptoms like difficulty walking and talking. 

  1. Night Blindness 

Some people suffer from a condition which is called night blindness. This means it’s harder to see in the dark for those people, than others. Sometimes it can be caused by a shortage of vitamin A, which is also why it’s more common in poor countries. 



  1. Dry Eyes

Dry eyes can have many causes. Allergies are the most common cause of dry eyes. Another reason could just be being exposed to very dry air for too long. Another, more serious cause, could be Sjogren’s syndrome. This is a very rare immune system disorder. 

  1. White Spots in the Eyes

People who wear contact lenses often are at risk to get a corneal infection. This can cause white spots in the cornea of the eye. If you do wear lenses, be sure to always properly clean them, not to wear them overnight (except with night lenses) or longer than 8 hours a day. Also, be careful with taking out and putting in your lenses. Your eyes are very sensitive!



  1. Red Eyes 

Red eyes can be caused by several things. The first thing to think about is not enough sleep or allergies. If you don’t have a clear reason for your red eyes, they could be a signal of several diseases like diabetes, glaucoma, and high intracranial pressure.

  1. Seeing Colorless Specks 

If you’re seeing specks, you don’t immediately have to worry. But if you notice that you’re seeing them constantly or suddenly much more often, you should think about visiting your doctor. Seeing specks could be a sign of a retinal tear that should be treated quickly or otherwise could lead to blindness. 



  1. Yellow Spots Near the Iris

Yellow spots in the eyes (not to be confused with yellow eye-whites) are mainly found in elderly people and people who have been exposed to a lot of sun-light in their life. It’s called pinguecula, and luckily it doesn’t have any negative effects on your vision!

  1. Tearing Eyes

Aww, you’re crying?! – nope. You probably just have teary eyes. Teary eyes can be a sign of dry eyes, but it can also be caused by too much screen exposure. If it’s really bad, and you also have trouble with closing one eye, it could be a sign of partial paralysis. This should be a warning sign to immediately visit a doctor.



  1. Seeing Small, Dark Spots 

If you’re seeing dark, small spots, it might be a sign of poor cerebral circulation. They can be a normal sign of aging, but there are some conditions that make you more at-risk to see these dark spots, such as diabetes and several metabolic disorders. 

  1. Losing Patches of Vision 

If you have migraines, you might be familiar with this visual problem. It’s called a migraine aura, causing you to temporarily lose parts of your vision, especially when you’re trying to focus on a certain object. It’s completely harmless, but it can be dangerous in traffic. 



  1. Cataract 

When you have a cataract, your lens becomes blurry and cloudy. It’s mostly seen in elderly people, and it can be surgically treated. In younger people, cloudy eyes can be a warning sign of tumors, diabetes, or certain medications. 

  1. Eyebrow loss

Okay, not really the eyes, but very close: the eyebrows. Loss of eyebrow hairs can be caused by stress or aging, but there are also more serious possible causes, such as thyroid problems.
