When light enters the eye, it hits a light sensitive neural layer of tissue near the back of the eye called the retina.
That’s where phototransduction occurs, which is the process by which light waves are converted into electrical signals.
Afterwards, these electrical signals are sent to the brain for visual processing.
The left visual field can be divided into two halves.
When light enters the eye, the temporal field of vision is projected to the opposite side, onto the medial nasal retina, and the nasal field of vision gets projected to the opposite side, onto the lateral temporal retina.
