Maybe the retina isn't visible to the human eye, and vanishers can make parts of them visible-Wraith does it with his robes-and so they do that to thier retinas, that way they can become invisible and see. Or maybe it is something else that humans haven't figured out. Or it's just part of the power. Or their eyes work differently. Or maybe certain light reflects, while what they want to bounce off bounces off.
