Why Do We Have Two Eyes?
Humans evolved with two forward-facing eyes for binocular vision.
Benefits include:
1. Depth Perception
Having two slightly different visual angles allows the brain to calculate distance.
2. Field of Vision
Two eyes expand peripheral awareness.
3. Redundancy
If one eye is damaged, the other still provides sight.
Predator species (like humans) typically have forward-facing eyes for precision and depth.
Can Eye Dominance Change?
In most cases, eye dominance remains stable throughout life.
However, it can shift if:
One eye’s vision significantly worsens
Injury occurs
Neurological changes happen
But generally, it stays consistent.
Cultural and Symbolic Interpretations of “Man’s Eye”
Sometimes the question isn’t biological—it’s symbolic.
