Can I Lose My Vision Suddenly?

Sudden vision loss could occur due to problems in different parts of the eyes, like the retina, cornea, or optic nerve. Vision loss may be slow or sudden. Besides, sudden vision loss could occur due to an accident. Slow vision loss could cause long-term medical complications.

Note that sudden vision loss is a severe medical condition that leads to complete blindness. It requires immediate medical attention. The condition is not only damaging for vision but is also life-threatening in some cases.

Causes for Sudden Vision Loss

The most common triggers for sudden vision loss may include eye trauma, blockage of blood flow, or any complication in the retina. Following are some of the most critical factors.

1.      Retina Damage

The retina is the exterior part at the back of your eye. Damage to the retina, including artery occlusion or detached retina, can lead to sudden blindness. It may also lead to partial vision loss. When any problem occurs in the macular (the area of the back of the retina), you can lose central vision while peripheral vision remains active.

2.      Eyestrain

Eye strain can arise when you use a computer or cell phone for a long time without any break. Besides, it may develop due to continuous reading and driving. Eye strain can be one of the reasons for vision loss.

3.      Vitreous Hemorrhage

Vitreous hemorrhage takes place when blood leaks into the vitreous part of the eye. It hinders the light from entering your eye and leads to sudden vision loss.

4.      Corneal Abrasion

The cornea is the covering part of your eye. If you injure or scratch your eye, it can result in corneal abrasion. It can lead to blurry vision as well as vision loss with severe symptoms.

5.       Temporal Arteritis

It is the inflammation in the medium-sized arteries. The condition can result in a throbbing headache in your forehead. If the condition worsens, it can lead to blurring vision or loss of sight.

6.      Injury

Any severe injury can also cause vision loss.

Direct Trauma to Eyes

Trauma to the surroundings of structures and tissues of eyes can lead to damage that impacts vision.

Head Trauma

Head trauma can also cause vision loss and nerve damage affecting your brain and eyes. It may happen due to a severe head injury or traumatic brain injury.

7.      Certain Medical Conditions

Certain medical conditions like stroke or brain tumor can cause vision loss. It is crucial to seek treatment for any medical condition before it worsens.

Migraine headache

It is one of the primary reasons for sudden vision loss in one or both eyes. It is the severe headache that many individuals face on one side of the head.

Neurologic disease

Different neurological diseases can disturb the connection between the eyes and brain and lead to sudden blindness


If you experience any of the symptoms discussed above, you need to get an immediate check-up. Sudden vision loss may recover depending on the symptoms and severity level. Earlier treatment can enhance the chances of betterment.
