Night blindness, also known as nyctalopia, involves poor vision at night or in a dimly lit environment. This makes driving or any other activities done in such situations more difficult.
Vision Care Plus, your local provider of eyeglasses and contacts, discusses what you need to know about night blindness, including causes, treatment and prevention.
Night blindness can be a complication of several eye-related conditions including nearsightedness, cataracts (the clouding of the eyes’ lenses) and retinitis pigmentosa or the collection of dark pigments in the retina that causes tunnel vision.
Seniors are at a higher risk of developing cataracts, which means they are also more likely to experience night blindness. In rare cases, a severe lack of vitamin A can also lead to this condition. Vitamin A is essential in transforming nerve impulses into images in the retina or the light-sensitive area in the back of the eye.
Fortunately, the eye conditions that cause night blindness are treatable. Cataracts can be removed via surgery, during which the clouded lens is replaced with a clear, artificial lens. Myopia can be controlled through prescription contact lenses or eyeglasses. Finally, vitamin supplements may be prescribed for patients with low vitamin A levels.
Night blindness caused by a birth defect or genetic condition like Usher syndrome can’t be prevented. However, eating a balanced diet is one effective way to reduce the chances of cataracts, which then minimizes the risk of night blindness.
