Its heat vision because it can be used to view the electromagnetic radiation emitting from people’s bodies which corresponds to body heat. IR corresponds to heat just as much as the the visible spectrum. Its just named for the use most people associate with it.

IR exists in remote, if that were more popular it would be called remote rays instead
