5 Common Eye Symptoms Explained

Have you ever been sitting quietly, perhaps watching television, and out of nowhere your eye starts twitching?  It may seem to be completely random, but there are many possible reasons for this strange occurrence.  In fact, people often experience eye symptoms that are questionable.  What do they mean?  Do you need to seek treatment?  Here are a few common eye symptoms and what may be causing them.


One of the more common eye symptoms is waking up with some crust, or “sleep”, in your eyes, and is perfectly normal as it is simply residue from the eye’s natural protective process.  However, while finding crust-like residue in the corners of your eye or on your lashes is fine when waking after sleeping, crusty eyes during waking hours could be caused by a condition known as blepharitis, or inflammation of the eyelids, which you should get medical attention for.  In fact, any eye discharge that is more than simple flakes after sleeping could be an indicator of a greater issue, such as dry eye or pink eye (conjunctivitis).

Red eyes

Red eyes are another one of those eye symptoms that is usually harmless, but not in every case.  Red eyes occur when the tiny blood vessels on the whites of your eyes expand, making them appear red.  In most instances, it is caused by a relatively harmless factor like fatigue, allergies, smoke, chlorine or wearing your contacts too long.  However, red eyes that last more than a day or two could indicate a more serious problem such as an eye infection, a corneal ulcer or glaucoma.

Eye twitching

Almost every person experiences some form of eyelid twitching in his or her lifetime.  Known medically as myokymia, these involuntary spasms of the eyelid muscles can occur every few seconds over the course of several minutes.  Typically, eyelid twitching is a harmless annoyance brought on by stress, lack of sleep, caffeine, tobacco use or even exercise.  But in some cases, it can result from a more serious issue.  An eye twitch that doesn’t go away relatively quickly can be a sign of a brain or nerve disorder such as Bell’s Palsy, Parkinson’s Disease, Tourette Syndrome or Multiple Sclerosis.

Blurred vision

Some eye symptoms, like blurred vision, could indicate a serious issue and should be discussed with your eye doctor.  Blurred vision can indicate myopia (distant objects are blurry), hyperopia (difficulty focusing on close objects), astigmatism (blurred vision at all distances) or presbyopia (normal age-related vision problem).  Each of these conditions can be treated relatively easily with corrective eyeglasses or contact lenses.  However, there are more serious conditions that might be present if you are experiencing blurred vision.  These could include cataracts, glaucoma, age-related macular degeneration, diabetic retinopathy or cardiovascular disease.

Yellow eyes

A yellow appearance in your eye can be harmless, or serious, so it is important to see your eye doctor for an accurate diagnosis.  For example, yellow spots on your eyes can simply be protein, fat or calcium growths that are not a cause for concern unless they are interfering with your vision.  In contrast, if the whites of your eyes are instead yellow, that can be a sign of jaundice which could be caused by hepatitis, gallstones or even liver cancer.

You can never be too careful when it comes to taking care of your vision.  Even a simple issue could be a sign of a more serious problem if it doesn’t clear up quickly.  So it’s important to trust your gut when it comes to any kind of problem that you are experiencing with your eyes.
