Impaired night vision, also known as nyctalopia, is a symptom of an underlying problem affecting your ability to see in low light. This condition can be caused by a variety of factors and can have a significant impact on daily activities and quality of life.
One of the main causes of impaired night vision is vitamin A deficiency. Vitamin A is essential for the functioning of the retina, which is the part of the eye that allows us to see in low light. Without enough vitamin A, the retina cannot function properly, leading to difficulties with night vision.
Other potential causes of impaired night vision include cataracts, nearsightedness, and certain genetic conditions. In some cases, medications and eye surgeries can also contribute to this condition.
Symptoms of impaired night vision can vary depending on the underlying cause but often include difficulty seeing in dimly lit environments, increased sensitivity to glare, and decreased ability to distinguish objects in low light.
Treatment for impaired night vision depends on the underlying cause. In the case of vitamin A deficiency, supplementation or dietary changes may be recommended. For other causes, corrective lenses, surgery, or other medical interventions may be necessary.
