Nyctalopia is often referred to as what?

Nyctalopia is commonly referred to as night blindness. This condition is characterized by an impaired ability to see in low light or darkness, making it challenging for individuals to adjust to dark environments. Night blindness can result from various causes, including vitamin A deficiency, certain eye diseases like retinitis pigmentosa, or damage to the retina. This condition specifically affects the rod cells in the eyes, which are responsible for vision in dim light.

Understanding this term is significant, as it highlights the importance of proper eye health and nutrition, particularly the role of vitamin A in maintaining good vision. In contrast, the other options pertain to different aspects of eye health or vision anomalies, but do not accurately describe nyctalopia.
