How eyes works? (Animation) explained within one minute.

How do Eyes work to create a vision? Light passes into the eyes through the cornea and the anterior chamber into the pupils. The iris may dilate or constrict to determine how much light gets to the lens. Then lens moves light through the clear cavity called the vitreous and focuses it on the retina. The retina then converts this light energy into electrical impulses and passes it through the optic nerve also called the second cranial nerve.. These impulses then travel through the optic nerve into the primary visual cortex is located in the most posterior portion of the brain's occipital lobe. While it may sound like a lengthy process, but takes around only 13 milliseconds.
