line of sight
Unobstructed viewing path
Line of sight is the straight path between an observer's eye and what they're looking at.
If something blocks that path, you lose line of sight: A pillar obstructed my line of sight to the stage.
The concept matters in contexts from military targeting to wireless signal transmission—anything requiring an unobstructed direct path between two points.
