A sudden loss of vision doesnt necessarily mean total blindness. Sudden blindness can occur in one eye or both eyes, and the loss of sight can be partial or total.
With total vision loss, the sight in the affected eye (or eyes) is lost completely, so that nothing can be seen with the affected eye. With partial vision loss, some sight may remain in the affected eye.
Sudden vision loss can include a sudden loss of peripheral vision, sudden loss of central vision, or even a sudden blurring of your vision. The sudden appearance of spots within your field of vision could also a symptom of a more serious condition.
Sudden blindness may only last a short time, such as a few seconds, minutes or hours. However, it could potentially be permanent, especially if not treated quickly.
Sudden loss of vision can occur for a number of reasons. Many underlying problems are very serious, and could potentially be sight-threatening or even life-threatening. Its therefore essential to seek medical help as soon as possible if you experience any sudden loss of sight.
