Question

what happens if angle vision is greater than 60°

Answer 1

The approximate field of view of an individual human eye is 95° away from the nose, 75° downward, 60° toward the nose, and 60° upward, allowing humans to have a slightly more than 180-degree forward-facing horizontal field of view.

There is a central area where both eyes see together for Binocular or Stereoscopic (3D) vision.
