At the optic chiasm, the visual system performs something incredibly precise:

𓆩👁️𓆪 NASAL RETINAL FIBRES CROSS.
𓆩👁️𓆪 TEMPORAL RETINAL FIBRES STAY IPSILATERAL.

Why?

Because the brain isn’t trying to organize vision by LEFT EYE vs RIGHT EYE.

It’s organizing it by LEFT SPACE vs RIGHT SPACE.

So:

LEFT VISUAL FIELD → RIGHT HEMISPHERE
RIGHT VISUAL FIELD → LEFT HEMISPHERE

The two eyes are essentially feeding overlapping information into both hemispheres, and the chiasma helps reorganize that information so the brain can construct a coherent representation of the world around you.

And here’s the beautiful part:

It is one of the places where the nervous system reorganizes raw sensory information according to spatial reality.
