Night Blindness :
Night blindness is an eye condition affecting the vision in low light areas, particularly during night time. It is medically termed as nyctalopia. It occurs due to limited entry of light into retinas and structural abnormalities of retinas. Individuals dealing with night blindness face difficulty navigating in dim lights, and have trouble performing activities or driving cars at night. Some of the rare genetic disorders, glaucoma, cataracts and severe vitamin A deficiency conditions can increase the risk of acquiring night blindness. A certified eye specialist evaluates the medical history with clinical symptoms and conducts specialized vision tests to rule out underlying causative conditions. Treatment of night blindness is curable only if it due to treatable conditions, night blindness caused by some genetic disorders cannot be cured. A treatment regimen with vitamin A supplements, surgical management of glaucoma or cataracts, use of contact lens or eyeglasses for refractive vision errors, and living a healthy lifestyle helps in management of night blindness. Annual eye and vision exams with eye specialists help in early detection and prevention of progression of night blindness.
