Generally, tigers have yellow or amber eyes with black irises.The exception is the white tiger, which typically has blue eyes.
A tiger's light-colored eyes help it to see at night. A tiger can see roughly six times better at night than a human can. They have round pupils to help them see better during the morning and evening hours, when they do the majority of their hunting.
White tigers have blue eyes because of the gene for blue eyes linked to the gene causing their white fur. Despite having blue eyes, a white tiger has the same exceptional night vision as a regular tiger.
Tigers are almost entirely blind for the first week of their lives. Because of this, almost half do not survive into adulthood.
