Dizziness & Blurry Vision: What Do They Mean?

9 Factors That Lead To Dizziness And Blurry Vision

If you find yourself squinting your eyes to get a clear view of something, it’s safe to say you have blurry vision.

While some people prefer blinking or rubbing their eyes, others to squint, the reason is all the same: blurry vision.

But how, exactly, do you end up with dizziness and blurry vision?

Here ere are a few that may lead to dizziness and blurry vision.

  • Stress

Blurry vision and dizziness are two symptoms that come with a variety of health conditions and can make daily life unpleasant. They often occur together. The causes of these symptoms can range from mild to more serious, so it’s important to pay attention to what your body is telling you.

Let's break down some situations that may cause dizziness & blurry vision.

Stress & Anxiety

Feeling stressed out or anxious can lead to increased muscle tension, including the muscles that control your eyes. It's possible that this could lead you to have blurry or double vision. If you tend to narrow your eyes during times of stress, anxiety, or depression, it's even more likely that you'll experience blurry vision.

Anxiety can cause hyperventilation and rapid breathing, which may make you light-headed or dizzy. 

Age-related eye changes

As you get older, your eyes' ability to focus on objects near and far may decrease. This change is called presbyopia. Some people experience presbyopia with eye dryness or fatigue, which may lead to feeling dizzy or light-headed.

Changing your glasses or contacts prescription

If you have an old pair of glasses or contacts and need a new prescription, you might experience blurry vision and eyestrain, which can make you feel dizzy. You may also experience these symptoms if you're wearing someone else's glasses or contact lenses. Blurred vision can be caused by eye conditions such as nearsightedness or farsightedness.


Any medication you take for another health condition may cause dizziness or affect your vision. These side effects are most common with high blood pressure medicines, antihistamines, antidepressants, antipsychotic drugs, narcotics and a class of medications used to treat Parkinson's disease called anticholinergics. It's important to tell your doctor if any medication makes you feel dizzy or impairs your vision so he or she can determine if it is safe for you to drive or operate machinery.


Dehydration is another cause of dizziness and blurred vision. Your body loses water when you sweat excessively, have diarrhea or vomit repeatedly during an illness, take diuretic medications that increase urine output ("water pills"), drink too much alcohol, or don't drink enough fluids each day (especially water).


You may be familiar with the common symptoms that accompany an allergy, such as a cough or runny nose. However, you may experience some surprising symptoms, too. You may notice that your eyes are swollen or watery, and you could have blurry vision. Some people also have dizziness and a general feeling of being unwell when they have allergies.

Migraine headaches

Dizziness and blurry vision are symptoms that may be caused by a condition known as a migraine. Migraine is an intense type of headache that typically includes nausea and sensitivity to sound and light. In many cases, migraines can also cause dizziness and blurred vision. Migraines can last anywhere from four to 72 hours.


Dizziness is the sensation that either you or your surroundings are moving. It can range from a mild sense of haziness to a complete loss of balance and equilibrium. Blurry vision is an inability to see clearly.

The two symptoms — dizziness and blurry vision — often occur together, but they can be entirely separate issues. If you're experiencing both dizziness and blurry vision, it may indicate a medical problem that requires treatment.

One important thing to remember is that if you suddenly develop dizziness or blurred vision, it may be a sign of a serious medical condition — go to the emergency room right away!
