Yes their eyes are a definate clue but they will also get duller yellow in color. Their bellies will turn like an off whitish sort of color. And sometimes on their skin you'll get these brown almost dirty looking patches. My female will get these little spots every once in a while and they are gone after the shed. I took a picture of it the first time I saw it. I'll try and find that. It all depends on the animal, albino variation etc. You just will have to learn the signs to the individual albinos.
