Most Common Causes of Blurred Vision

You can easily navigate the world when your vision is sharp and clear. You can read traffic signs and fine print, ensuring you do not miss a step in your endeavors. However, blurred vision will make you feel like having a filter over your eyes. You will no longer be able to see objects and images with sharpness.


Common Symptoms of Blurred Vision


If you are constantly squinting, rubbing your eyes, or blinking rapidly, you could be experiencing blurred vision. The condition is common and treatment is readily available. However, sudden changes to your vision are abnormal. You should see your ophthalmologist if this happens.


Causes of Blurred Vision


So, if you are wondering what causes blurred vision, here are a few pointers.




Diabetes increases your risk for an eye condition known as diabetic retinopathy. High blood pressure due to diabetes may cause damage to the small blood vessels in your retina. In turn, this can cause the macula to swell because there will be bleeding, new, and unwanted blood vessels in your eye. These events can lead to blurred vision and other symptoms, including permanent blindness.




Pregnant women should take blurred vision very seriously. You could be suffering from preeclampsia, a serious condition characterized by protein in your urine and high blood pressure.


It happens late in the pregnancy and to women who never suffered from high blood pressure. While the condition may not exhibit any symptoms, blurred vision and other vision changes could be clues that you have preeclampsia.




One of the most noticeable signs of experiencing a stroke is an abrupt yet painless vision change. You might experience blurred or double vision. If you notice these and other signs of stroke, call the emergency services immediately.


Besides blurred vision, people experiencing stroke also show signs such as face-drooping, dizziness, slurred speech, numbness in one arm, and balance loss.


Multiple Sclerosis (MS)


One of the earliest symptoms of MS is blurry vision. The condition causes inflammation along the optic nerve. This is the nerve connecting your brain to your eyes. This condition is expertly known as optic neuritis and can result in blurred vision, pain, and color vision loss.




A migraine is a lot more than just a bad headache. The pain comes with several other symptoms, such as sensitivity to light and blurred vision. You could experience the symptoms even before the migraine and may last until it passes. Aura describes more dramatic changes that may occur to your vision during a migraine. They include:


  • Seeing spots or wavy lines

  • Full or partial vision loss for a short time, usually not more than 30 minutes


In Conclusion


Whether the blurred vision results from any of the above causes or not, you should regularly get eye exams. But when blurred vision occurs suddenly, it could be a sign of a more serious issue. You should seek medical attention immediately.
