It is a simple matter for axons of the optic nerves to follow the "stalk" of the retina back to the rest of the brain. In an animal like humans with over-lap in the visual fields of the two eyes, [http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Search&db=books&doptcmdl=GenBookHL&term=optic+nerve+AND+neurosci%5Bbook%5D+AND+231345%5Buid%5D&rid=neurosci.section.816 not all] of the axons in the [[w:Optic nerve|optic nerves]] cross to the other side of the brain. This allows information from the two eyes about the same object to be combined in the brain.
