Uhm, no. We can't see infra-red radiation. In a room truly devoid of visible light human eye can't see a thing. However, most dark rooms contain certain amounts of dissipated visible light, coming through even very tiny openings - like spaces under doors, key-holes, between threads of fabric of which curtains are made and so on. Our eyes are really sensitive to even tiny amounts of light - on a dark night they can see a candle-light 30 miles away. It just takes them a while to adjust to different light levels.
