Tigers typically have amber or golden eyes with black irises.
The white tiger is an exception; it normally has blue eyes.
Light-colored eyes aid a tiger’s ability to see at night. A tiger can see at night about six times better than a human. For improved vision in the morning and evening, when they do the majority of their hunting, they have spherical pupils.
Due to a genetic relationship between the gene generating their white fur and the gene for blue eyes, white tigers have blue eyes. A white tiger has the same excellent night vision as a regular tiger despite having blue eyes.
For the first week of life, tigers are nearly completely blind. As a result, over half do not live to adulthood.
