The outer visual field of the left eye

Let's apply the basics to the outer visual field of the left eye. Because of the lens, the image in the outer half of the left eye (the spade) is projected to the inner half of the left eye retina and action potentials are generated. Also, as the fibers from the inner half of the retina cross the right-left midline, the image signals reach the right cerebral cortex via the right optic tract.
