Eye

Paired visual organ (~24 mm diameter); converts light into neural signals via rods (scotopic) and cones (photopic/color) in the retina. Outer tunic: cornea/sclera; uvea: iris/ciliary body/choroid; retina: 10 neural layers. ~1 million axons per optic nerve.

Also known as: ocular organ, eyeball, globe, oculus, visual organ
