There are few differences between the vision of cattle and that of humans. The cattle do not see the color red, since the number of cones (the receptors placed on the retina) sensitive to this color is insignificant: if a bull has in front of him a person dressed in red, in reality he perceives a "being" of Color: Grey. Compared to humans, cattle see white, black and color contrasts more sharply. So they can better define the contours of objects. Instead, their binocular vision and their field of vision are smaller. Their night vision is better and adapts faster in the dark. On the bottom of the eye of cattle is the so-called shiny carpet, rich in guanine, which reflects light rays and allows the animal not to be dazzled.
