Blurred Vision in One Eye






The vision would become blind in one eye due to several conditions. The reasons vary widely ranging from simple reason of crying for long time to serious medical issues like brain damage. Blurred vision in one eye and both the eyes for that matter is caused due to refractive error which can easily be corrected by wearing the right eyeglasses.

Because of blurred vision, the visual activity in one eye may get reduced and the affected person may not be able to see objects present at some distance. This would cause Cloudy Vision or difficulty in reading and even eye pain and irritation. In rare cases, blurred vision is an indicator of serious medical issues like nerve collapse in the brain or brain tumor.

Symptoms :

Dryness in the eye, increased sensitivity, excess of discharge or tears from the affected eye, eye pain and irritation, bloodshot eyes, reduced eyesight during night and Headache are some of the symptoms of blurred vision in one eye.

Any trauma or injury on the eyes can also cause visual impairment or blurred vision for some time. Sometimes, cataract problem can also cause blurred vision in one eye. Prolonged diabetes (diabetic retinopathy) and use of strong medications can also affect the visual capacity of the eyes, affecting one or both the eyes.

Blurred vision occurs due to Macular Degeneration disorder resulting from old-age. It can be caused due to headache, migraine, Myopia and persbyopia and Uveitis (inflammation of the eye).

In rare cases, it can be caused due to serious problem like brain damage or disorder in the central nervous system. Some of the other life threatening conditions that can cause blurred vision are Glaucoma (excess of eye pressure), inflammation of the optical nerve on the eyes and retinal detachment.

Diagnoses :

Your eye doctor will examine the eye for detecting the causative factor for blurred vision.

Treatment :

Your doctor will first diagnose the root cause of the disease before starting treatment. Normally discharge from the eyes will get settled in few days and if you continue to have blurred vision you should consult your doctor.

Blurred Vision in One Eye Causes

As mentioned above blurred vision in only one eye can be caused by numerous underlying diseases or conditions. Optic neuritis which is inflammation of the optic nerve can cause blurred vision that in the beginning starts in only one eye. This type of blurred vision can also be a symptom of disorders occurring in the central nervous system or brain, such as migraine Headaches or a tumor pressing on the optic nerve. Trauma to the eye is another cause that can affect only one eye, either from an injury to the eye itself or from delayed effects such as formation of a cataract.

Additionally, conditions that are system wide such as diabetes can cause retinal or cataract conditions that might lead to blurred vision. There are also some medications that might have blurred vision as a side effect but normally that would affect both eyes.

• Cataracts – loss of transparency or clouding in the lens of the eye


• Diabetic retinopathy, cataracts and blindness – vision complications of diabetes


• Dry eyes


• Migraines


• Myopia – nearsightedness; not able to focus on distant objects


• Need for corrective lenses


• Presbyopia – age-related farsightedness or inability to focus on objects that are near


• Uveitis and iritis – inflammation of eye structures

Serious Causes
Life-threatening or serious causes of blurred vision in one eye include:

• Brain tumor


• Eye trauma


• Glaucoma – disorder causing damage to the optic nerve, as result of pressure in the eye that is increased


• Optic neuritis – inflammation of the optic nerve


• Retinal detachment – detachment of the layer in the eye that is light-sensing from the blood vessels which provides the eye nutrients and oxygen


• Stroke


• Transient ischemic attack – temporary symptoms that are Stroke-like that might be a sign or warning of an stroke that is impending
