How far can the human eye see?

A. 3 Miles B. 4 Miles C. 5 Miles 

A. 3 Miles 

Why the 3-Mile Limit?

  • Earth's Curvature: The Earth is a sphere, so at a certain distance, the planet's surface curves away, and objects fall out of sight. 
  • Horizon: The 3-mile limit is the point where the horizon line obstructs your view.
