Line of sight is necessary, but not sufficient, for a gaze attack to function; you must also be within range.You're in range when you succeed on a Spot check sufficient to see the creature's eyes. Most eyes are Fine objects, resulting in a Spot DC of 0 within 10', with penalties for greater distance.
