The Amazing Human Eye

Eye Structure

• The lens of the eye acts like a camera lens, controlling the amount of light that enters the eye.
• The iris is the colored part of the eye that controls the amount of light entering by adjusting its size.
• The pupil is the part of the eye that lets light into the eye.
• The ciliary muscles help the cornea to focus light onto the retina by changing the shape of the lens.
• There are two types of cells in the retina: rods and cones, which are responsible for detecting light and transmitting visual signals to the brain.
