What is the function of the Lens?

• Light travels through here and helps focus the image onto the retina.

• The lens regulates the temperature of the eye.
• The lens protects the eye from dust and debris.

What is the function of the Cornea?

• The cornea bends light toward the pupil.

• The cornea produces tears for lubrication.
• The cornea is responsible for color vision.
• The cornea regulates the pressure inside the eye.

What is the function of the Pupil?

• The function of the pupil is to control the retina

• The pupil helps in focusing on distant objects.
• The pupil is a hole which allows light to enter the eye

• The pupil protects the eye from foreign objects.
