Do albino people have red eyes?

Types of albinism

OCA causes decreased pigment in the skin, hair and eyes, as well as vision problems. The amount of pigment varies by type, and the resulting color of skin, hair and eyes also varies by and within types. Ocular albinism is mainly limited to the eyes, causing vision problems.
