10 Reasons You Might Have Blurred Vision

One of the most common eye problems is blurry vision. It can be caused due to issues in various eye components, such as the optic nerve, retina, or cornea. Blurred vision can be a symptom of both a serious condition requiring immediate treatment and less severe, but still important, conditions.

Here are 10 common causes of blurred vision.

Detached Retina

Detached retinas occur when the retina is disconnected from the rear part of your eye, losing the nerve connections and blood supply in the process.

Wet Macular Degeneration

Wet macular degeneration can take place in the retina’s center, called the macula. The condition is characterized by abnormal vessel growth, leading to blood leaks and blurry vision.


Your vision can be blurry if a stroke affects the section of the brain controlling vision. If so, your vision will be lost or blurred in one eye.


Conjunctivitis, also known as pink eye, is caused by viruses or bacteria that infect the eye’s outside lining. Another potential culprit is allergies.

Corneal Abrasion

Corneal abrasion can develop if your cornea gets injured or scratched.

Eye Strain

You can develop eye strain if you’re focused on something, like a computer screen, for an extended period. One of the consequences of eye strain is blurry vision.


Another cause of blurred vision is keratitis. This condition is usually brought about by an infection and affects the cornea.

Macular Hole

If there are breaks or tears in the macula, you can develop blurry vision.

High Sugar Levels

If your blood sugar level is extremely high, your eye’s lens can swell and lead to blurred vision.

Migraines With Aura

If an aura (sensory changes like seeing quick flashes of light or a tingling sensation) precedes your migraine attacks, your vision can get blurry. You can also experience other sensorial disturbances.

Bottom Line

The list of blurred vision causes doesn’t end here. There are many more problems that can lead to this condition, all of which may require some medical attention. If you experience a stroke or other emergencies, seek medical attention immediately.
