The fovea, directly behind the lens, consists of mostly densely-packed cone cells. Rod cells are highly sensitive to light allowing them to respond in dim light and dark conditions, however, they cannot detect color. Some aquatic animals have a second eyelid in each eye
Without changing input, these cells would otherwise stop generating output.g.e.
