What term is used for insufficient vision in dim light conditions?

• A. Night blindness
• B. Glare resistance
• C. Speed smear
• D. Tunnel vision

Answer: (A)

Night blindness is the correct term for insufficient vision in dim light conditions. It refers to a condition where individuals have difficulty seeing in low-light situations or at night. This can be caused by a variety of factors, including vitamin A deficiency, retinitis pigmentosa, or cataracts, which impair the eye's ability to adjust to darkness. As a result, people with night blindness may struggle to see adequately when transitioning from brightly lit areas to darker environments, making nighttime driving particularly challenging. Glare resistance refers to the ability to cope with bright lights and is not related to low-light vision. Speed smear is a phenomenon where fast-moving objects become blurred, not affecting low-light conditions. Tunnel vision is a term used to describe a loss of peripheral vision, where one can only see straight ahead; it does not pertain directly to difficulties in dim light. Each of these terms relates to different aspects of vision and its challenges, but night blindness specifically indicates a deficiency in dim light visibility.
