I raise mice, and pink eyed white ("albino") mice do have poorer eyesight but mice in general see very poorly so it isn't obvious. Rats which have pink eyes are the same and will often sway their head to bring things into focus. In leopard geckos, pink eyed animals exposed to bright light will usually tightly shut their eyes until it dims, it is very painful. They can go permanently blind if kept under bright light constantly.My kids used to raise mice, and it didn't seem that the albino mice had any trouble seeing. What does pigment or eye color have to do with sight?
