Which eye is man’s eye ??

It describes perspective, not vision mechanics.

Medical Conditions Affecting Eye Use
Some conditions impact how eyes function together:

Amblyopia (Lazy Eye)
One eye doesn’t develop normal visual acuity. The brain may rely more heavily on the stronger eye.

Strabismus
Misalignment of the eyes can affect dominance and depth perception.

Monocular Vision
Vision in only one eye significantly reduces depth perception.

These aren’t gender-specific.

How the Brain Blends Two Images into One
Your brain performs something remarkable every second.

Each eye sees a slightly different image. The brain fuses them into a single, 3D perception.

This process is called binocular fusion.

Without it, the world would look double.
