When a character's gaze is directed to something off to their side. Most commonly are eyes looking 90 degrees across the shoulder, but may also include up to 45 degrees facing in either direction.
Looking to the side is relative to the character's front, not the viewer's perspective. If the eyes are directed more than 45 degrees backwards use looking back instead.
If the character looks to the side without moving their head, combine with sideways glance. Not to be confused with averting eyes, where someone deliberately diverts their gaze from the viewer/others out of embarrassment , anger, annoyance, etc.
