I've read some rumors that say that Albino/Lutino budgies (budgies that are all white or all yellow with red eyes) are possibly blind or suffer from extremely diminished vision. This is merely a myth. Albino and Lutino budgies are able to see just as much as other budgies.
The "ino" gene in Albino and Lutino budgies removes all the melanin (substance that creates the dark colours) in the budgie's colour scheme. The dark color of the eye is gone, leaving a red eye with the white iris ring. You can see this clearly on the budgie on the left.
