peripheral vision
Seeing without looking
Peripheral vision is what you see at the edges of your visual field—the area you perceive without looking directly at it.
Objects in peripheral vision appear less sharp than those in focus, but the eye detects motion there more readily.
I caught movement in my peripheral vision and turned to look.
Figuratively, awareness at the edges: Keep it in your peripheral vision.
