EYE VISION - Part 2

Dark adaptation and light adaptation are in the visual function.

The light seems intensely and even uncomfortably bright until the eyes this threshold is called as light adaptation. The eye can move with the help of the muscles. There are four types of eye movements each controlled by a different neural system but sharing the same final common path.
