Sudden Blurred Vision

Blurred vision can be described as a change in vision where the usual sharpness of the eyesight goes missing. As a result, the person fails to see the minute details of the objects around him or her. Basically, it has two different forms. One is the sudden onset of blurred vision, and the other one is gradual blurriness of vision over a period of time.

Causes of Sudden Blurry Vision

A sudden blurriness in front of the eyes can be a scary experience for anyone. It is triggered by different factors that include aging, injury to the eyes, eye infection, and so on. Its main possible causes are as follows.

Eye Infection

Blurred vision can be a symptom of minor eye infection like pink eye. As the mucous formed inside the eyes due to the infection is wiped over the cornea during blinking, one experiences blurriness. The vision becomes clear within a few seconds, when the next blinking action wipes off the mucus. Any corneal infection like herpes can also lead to similar kind of problem.

These infections can be successfully treated with the help of suitable medicines such as antibiotics and antiviral medications.

Retinal Detachment

This is a serious problem where the retina of the eye gets detached. Initially, patients complain about presence of a dark shadow at the edge of their visual field which gradually comes down and covers the central part of the vision. Other symptoms of this condition are presence of floaters or moving tiny particles in front of the eyes and sudden flashes of light.

The treatment of this condition involves correction in the position of the retina by the means of surgery. Thus permanent loss of vision can be prevented.


Glaucoma is an eye disorder that causes extensive damage to the optic nerve and leads to blindness without the patient being aware of it. This happens when the pressure of the fluid in

the eyes increases. Sudden blurred vision is a sign of acute glaucoma. It is accompanied by intense eye pain, reddening of the eyes, improper night vision, loss of vision on both sides of the eyes, etc. Some people see halos when they look at lights.

Glaucoma patients with blurry vision should be given emergency medical attention as the pressure of the eye has to be reduced to inhibit any major damage.

Diabetic Retinopathy

This visual complication is found in those people who are suffering from diabetes. Inflammation occurs in the retina due to uncontrolled diabetes. This results in bleeding inside the retina and the vision becomes blurred all of a sudden. This condition may lead to blindness in the long run.

In this case, diabetes has to be controlled with proper treatment to prevent the recurrence of this ocular symptom.

Other Causes

Sudden onset of blurred vision in one eye can be a symptom of stroke. However, it is not the only symptom and is observed along with other stroke symptoms such as severe headache, dizziness, numbness on one side of the body, double vision or complete loss of vision, etc. Blurring of vision only while reading could be related to macular degeneration caused by aging. Some form of injuries to the eyes, migraine and hypertension could be responsible for sudden visual blurriness.

The treatment may vary according to the cause.

Any kind of visual problem can worsen in no time and have a serious impact on your life. Therefore, you should consult an ophthalmologist without any delay. The doctor would find out the exact cause of blurred vision and start the treatment accordingly. Strictly follow the instructions given by your doctor. Thus your normal vision will be restored or at least, any further damage to the eyes can be stopped.
