What can you see in the eyes of a cow?

Cows can only see black and white in their eyes.

Cattle belong to an animal family of Artiodactyla, Bovine and Bovine Subsubfamily, belonging to 5 genera. Most of them are extremely large herbivores, among which cattle, buffalo and yak are very important to human beings. Cows are strong animals, and both sexes have horns. They are strong and not good at running. Cattle are color-blind animals and cannot see other colors. The world they see is black and white.

Cone cells are the key to whether animals can see other colors, but there are no cones in cattle eyes. There are two kinds of cone cells in bovine retina. One is cone cells, which receive light with a wavelength between red light and green light, and the other is cone cells can feel blue light. It is difficult for a cow with only two kinds of cones to distinguish more colors.
