Sudden blurred vision, especially when accompanied by other factors, can be a symptom of various diseases and disorders. The following are some of the diseases and disorders associated with having sudden blurred vision.

Glaucoma: Glaucoma is often touted as the silent thief because you may have been losing your eyesight without you knowing it. Glaucoma is one of the leading causes of loss of vision. Symptoms may include sudden blurred vision, accompanied by nausea or vomiting, eye redness, severe eye pain, loss of peripheral vision and seeing halos around lights. A common type of glaucoma is primary open-angle glaucoma. This forms gradually and does not give warning signs so often enough, many people do not become aware of their eye problem until it is too late. Glaucoma is actually a group of diseases, the most common feature of which is damage to the optic nerve and a sensation of pressure on your eyeballs.

When it is accompanied by stringy or spotty bits in your vision, sudden flashes of light and the sensation that a curtain or shadow is being lowered onto your field of vision, you may be experiencing retinal detachment. Retinal detachment should be taken care of immediately. It is a medical emergency and time is of the essence. If the detached retina is not surgically put back into place, the patient may suffer permanent loss of vision. Unlike glaucoma though, retinal detachment gives out warning signs so you may be able to have yourself diagnosed and treated as soon as possible.

You may be suffering from a stroke if you are experiencing sudden blurred vision with loss of peripheral vision, sudden partial or total vision loss or double vision. Stroke is the third-leading cause of death in the United States. It is a medical emergency so the immediate treatment of stroke can spell the difference between life and death. Treating stroke early can also spell the difference between full recovery and a lifetime of paralysis or disability. Stroke happens when the brain tissue is deprived of oxygen and nutrients. This occurs when the supply of blood to the brain is reduced or severely interrupted.

Some other causes of it are diabetes, need for corrective eye surgery and hypertension. The less common of cause of sudden blurred vision might also be macular degeneration and migraine. Migraines can last up to 45 minutes before it subsides. In any case, if you experience this, you should contact your doctor immediately.
