Night Blindness :
Night blindness is a vision problem in which an individual finds it difficult to see in dimly lit places. It occurs when an individual's eyes cannot quickly adjust to changes in brightness. Night blindness is a symptom of a problem in the eyes. It may indicate a problem with the iris or the retina in the eyes.
Some of the possible causes of night blindness include glaucoma, cataract, vitamin A deficiency and genetic diseases like cone-rod dystrophy. An ophthalmologist can diagnose the condition by performing a thorough eye exam and ordering tests such as blood tests. In many cases, treating the underlying condition can resolve night blindness. The treatment may involve taking supplements or undergoing eye surgery. If night blindness stems from a genetic problem, then there may be no cure. However, an eye specialist can limit the effects of the condition to improve the patient's quality of life.
