I've noticed my beige rescue is easier to startle with fast movements, especially ones near his face, but he doesn't exhibit any of the other signs of vision problems you'd expect with animals with albinism and similar morphs (weaving, squinting, exaggerated reactions to light change, etc.). He tends to "WHOA WHAT THE HAY!" flip out and run if I touch him before he actually sees my hand move, but not if I turn on the overhead light or flick on a flash light in the dark.
