night blindness
Usage examples
  • The ability of our eyes to quickly view objects as they shift from light to dark areas and the ability to see in dim light or at night is an important part of our visual health. When we are not able to do such, the condition is referred to commonly as night blindness or medically as nyctalopia. It occurs as a result of various diseases that cause degeneration of the rods of the retina (the sensory cells responsible for vision in dim light). The problem can also appear as an inherited deficiency in visual purple, or rhodopsin, which is the pigment of the rods of the retina. The abnormality can also result from vitamin A deficiency. Rhodopsin, maintains its photosensitivity only in the presence of vitamin A.
