Although blind, Doctor Mid-Nite can see, unaided, in the dark. By means of his infra-red goggles, he can also sense heat patterns in a lit environment.

Physician Dr. Charles McNider was asked by the police to treat an important witness against mobster "Killer" Maroni. The witness had been shot in the back. While McNider was treating the dying man, a thug threw a hand grenade at them. McNider was blinded by the explosion. As a result he decided to do what he could to fight crime, and began by embarking on a second career as a magazine writer who would use his stories to expose criminals.
McNider learned that he could now see in the dark but was blinded by light, much like an owl. He developed special "infrared glasses" that would enable him to see in daylight as well. McNider then adopted the costumed identity of Doctor Mid-Nite and used it to capture Maroni. To keep his new identity secret, McNider only wore the infrared goggles as Doctor Mid-Nite and pretended to be completely blind.
Dr. Mid-Nite was a member of the All-Star Squadron and spent many years as a member of the Justice Society of America until it disbanded in the 1950s. He returned to active membership in the Society when it was revived.
