The human eye has two lenses that work together to focus light onto the retina. The outer focusing lens is called the cornea. The inner focusing lens is called the crystalline lens.

Light rays pass first through the cornea and then through the crystalline lens. The cornea and crystalline lens focus incoming light by bending all the light rays to meet at a single point on the retina.

From the retina, these light rays are sent as electrical pulses to the brain where our mind “sees” a picture of what’s in front of us.
