Superman's eyes, as everyone knows, emitted copious quantities of infrared 
photons, as well as streams of X-rays (although how he used the latter to 
see with has never been clear to me, since the whole point is that they 
mostly pass through objects rather than bouncing off them). But it's 
noticeable that he hasn't been in the news lately; I happen to know that 
he's lying very low, trying to evade the tremendously expensive class 
actions from families of all the people he killed with his X-rays, most 
heartbreakingly his radiation poisoned foster parents and the 
cancer-riddled Lana Lang and Lois Lane.
