They can thus see violet, blue, green and yellow light, but cannot see ultraviolet or deep red light. [5] [6] This was probably a feature of the first mammalian ancestors, which were likely small, nocturnal, and burrowing.

    For example, binocular vision, which is the basis for stereopsis and is important for depth perception, covers 114 degrees (horizontally) of the visual field in humans; [7] the remaining peripheral ~50 degrees on each side [6] have no binocular vision (because only one eye can see those parts of the visual field). Some birds have a scant 10 to ...

    Some applications can simulate color blindness by applying a filter to an image or screen that reduces the gamut of an image to that of a specific type of color blindness. While they do not directly help color blind people, they allow those with normal color vision to understand how the color blind see the world.
