Cornea: bends light as it enters the eye controls how much light enters the pupil focuses light on the retina contains light receptors carries impulses from eye to brain( bends light as it enters the eye, controls how much light enters the pupil, focuses light on the retina, contains light receptors, carries impulses from eye to brain )

Iris: focuses light on the retina carries impulses from eye to brain bends light as it enters the eye controls how much light enters the pupil contains light receptors( focuses light on the retina, carries impulses from eye to brain, bends light as it enters the eye, controls how much light enters the pupil, contains light receptors )

Lens: controls how much light enters the pupil contains light receptors carries impulses to the brain bends light as it enters the eye Focuses light on the retina( controls how much light enters the pupil, contains light receptors, carries impulses to the brain, bends light as it enters the eye, Focuses light on the retina )

Retina: carries impulses from eye to the brain bends light as it enters the eye contains light receptors focuses light on the retina controls how much light enters the pupil( carries impulses from eye to the brain, bends light as it enters the eye, contains light receptors, focuses light on the retina, controls how much light enters the pupil )

Optic Nerve: carries impulses from eye to brain focuses light on the retina controls how much light enters the pupil contains light receptors bends light as it enters the eye( carries impulses from eye to brain, focuses light on the retina, controls how much light enters the pupil, contains light receptors, bends light as it enters the eye )
