That's for sale???
I'm not arguing that. It's the same as in humans. However, I don't think that they are going to necessarily go blind if you have low level UV as they spend most of their time in hides and under substrate. The most I see my snakes is right now at breeding time when the males are active and out. The rest of the time, you mostly see them in the evening when the light would be out anyway. You can always adjust the timer on the light to stay on a shorter period for them if necessary. In several places around herer we have albino squirrels that not only survive, but thrive to reproduce more. As far as reduced vision, motion detection and smell etc. I never noticed any difference in feed response between my normals and my amels. As a matter of fact, my amel had the best and most aggressive feeding response of any of them, and would pursue any f/t on the tongs like a shark. The only time I really notice any problems with them is in deep blue. Then they really don't see for squat and that's all of them. I've not noticed that they respond any differently otherwise. They obviously survived in the wild as the first amel was collected from the wild and that's where we got all the future ones from....
