What is the role of the sclera in the human eye?

• It focuses light onto the retina.

• It produces visual signals.

• It is visible as the white part of the eye surrounding the cornea, iris, and pupil, and it protects interior structures.

• It regulates the amount of light entering the eye.

What role does the pupil play in vision?

• It focuses light onto the moon.

• It is an opening that adjusts the amount of light passing through by dilating or constricting.

• It protects the eye's interior structures.

• It translates light into nervous signals.

How does the retina contribute to vision?

• It protects the eye's interior structures.

• It carries signals to the lungs.

• It contains photoreceptor cells that translate light into nervous signals.

• It adjusts the amount of light entering the eye.

What is the function of the optic nerve in the visual system?

• It adjusts the amount of light entering the eye.

• It protects the eye's interior structures.

• It focuses light onto the retina.

• It carries visual signals from the eye to the brain for interpretation.
