Many people believe that all rabbits have red eyes, but that's actually not true! The color of a rabbit's eyes depends on the pigments in its body. Different breeds of rabbits have varying amounts of these pigments, which determine the color of their fur and eyes.
White rabbits belong to a pigment-free variety, known as the albino type. Because their irises lack color, you can see the blood vessels behind them, giving their eyes a red appearance. It's not that the eyes themselves are red—it's simply the reflection of blood seen through transparent tissue.
And no, eating carrots won't turn a rabbit's eyes red! That's just a common myth. A rabbit's eye color comes from genetics, not diet.
