"The name's somewhat descriptive, even if it is incomplete. As I said,
visibility refraction doesn't work right in their case. Somehow, they
pick up visual sensation right through a screen, regardless of its
adjustment. But things seen through a screen are distorted, and look
abnormal to them. Unless they're used to it, they get frightened when
they see a person with a refracted body shield. That's when the trouble
starts."
