The eye is a paired sensory organ that consists of the eyeball and the accessory organs. At the border of the brain and facial part of the head, the eye is embedded in the orbit: a bone cavity that serves to protect the eye from injuries.
The eye constitutes a complicated light refracting optic system (cornea, aqueous humor, lens, and vitreous body) and fully adapts to the need to zoom the light beam on the retina. If a person notices any object, the light from it firstly comes to the cornea, where light refraction and light centralization first occur. Further on the light penetrates the aqueous humor and pupil to the lens and a second refraction occurs. The lens zooms the beams penetrating the vitreous body so that they merge delicately on the retina, where a small upside-down picture of the observed object is projected.
