What is night blindness?
Night blindness, also called nyctalopia or nyctanopia, is a medical condition that affects a person’s vision, particularly at night or in an area with little to no light. In addition to having difficulty seeing at night, a person with night blindness may have difficulty seeing when moving from a brightly lit area to one that is dimly lit. As a result, individuals with night blindness generally experience difficulty driving at night or in the evening. It maybe that you require a small prescription to improve your vision in dark conditions. Poor nutrition, specifically a deficiency in vitamin A, can also cause night blindness although other causes such as cataracts or a problem with the retina can also contribute. If you think you may be suffering from this condition, an eye examination at your local Vision Express Optician may help to discover the root cause of it and suggest some measures to minimize or correct the effects.
