Human eye - Wikipedia
Humans have two eyes, situated on the left and the right of the face. The eyes sit in bony cavities called the orbits, in the skull. There are six extraocular muscles that control eye movements. The front visible part of the eye is made up of the whitish sclera, a coloured iris, and the pupil.

Structure and Functions of Human Eye with labelled Diagram
2021年6月24日 · The human eye is a roughly spherical organ, responsible for perceiving visual stimuli. It is enclosed within the eye sockets in the skull and is anchored down by muscles within the sockets. Anatomically, the eye comprises two components fused into one; hence, it does not possess a perfect spherical shape.
