Night blindness, also known as nyctalopia, is a vision impairment characterized by poor vision at night or in dim areas. Hence, it is difficult for individuals with night blindness to maneuver in the dark. The causes include nearsightedness, cataracts, vitamin A deficiency, and retinitis pigmentosa. The treatments include using corrective lenses, surgical removal of cataracts, and taking vitamin A supplements. However, this condition cannot be treated if it is caused by retinitis pigmentosa, a genetic condition.
