It begins at the area where information from the left eye and right eye cross (or âdecussateâ) to create a complete visual picture.The optic tract is actually comprised of two separate tracts: the left optic tract and the right optic tract.he left optic tract transfers information from temporal retinal fibers from the left eye and nasal retinal fiber from the right eye. The right optic tract transfers information from the temporal retinal fibers from the right eye and nasal retinal fibers from the left eye.
