I searched Google books to find that in the last 10 years a "cooperative eye hypothesis" has become popular: humans are the only primate species that have white sclerae because it created a uniquely human cooperative evolutionary advantage. However horses, penguins,some chimps,and many other animals also have white sclerae.

∙ 9y agoMany animals with a visible white sclera are mammals. Humans have more visible white sclera due to smaller irises. Animals like dogs, cats, cows, rabbits, etc. have white sclera. However, due to their large irises, the sclera only show when the irises are off-center, such as when they look to the side.

What the white part of the eyeball called?
The sclera, also known as the white of the eye, is the opaque (usually white, though certain animals, such as horses and lizards, can have black sclera), fibrous, protective, outer layer of the eye containing collagen and elastic fiber. It is derived from the neural crest. In children, it is thinner and shows some of the underlying pigment, appearing slightly blue. In the elderly, however, fatty deposits on the sclera can make it appear slightly yellow. The sclera forms the posterior five sixths of the connective tissue coat of the globe. It is continuous with the dura mater and the cornea, and maintains the shape of the globe, offering resistance to internal and external forces, and provides an attachment for the extraocular muscle insertions. The sclera is perforated by plenty of nerves and vessels passing through the posterior scleral foramen, the hole that is formed by the optic nerve. At the optic disk the outer two-thirds of the sclera continues with the dura mater (outer layer)
