Like others already noted, the albinos I've kept in the past had noticeably poorer vision than other snakes I've kept. Also, when some of my snakes (of normal
coloration) became geriatric, their vision also seems to suffer from when they were younger. My 19-year old corn snake is a good example...he has a good
appetite but grabbing his f/t mouse is much more of a challenge than it used to be.
