Parts of the human eye

What is the function of the cornea?

The cornea helps to focus light onto the retina and provides protection to the eye.

What is the function of the lens?

The lens adjusts its shape to help focus light on the retina for clear vision.

What is the function of the retina?

The retina contains light-sensitive cells that convert light into electrical signals, which are sent to the brain.

What is the function of the iris?

The iris controls the size of the pupil and the amount of light entering the eye.

What part of the eye is responsible for color vision?

The retina, particularly its cone cells, is responsible for color vision.

Label the parts of the eye in this diagram.

Include labels for the cornea, lens, retina, iris, pupil, and sclera.

What is the function of the pupil?

The pupil regulates the amount of light that enters the eye.

What is the function of the sclera?

The sclera provides structural support and protection for the eye.

What is the function of the vitreous humor?

The vitreous humor maintains the eye's shape and allows light to pass through to the retina.

What role does the aqueous humor play in the eye?

The aqueous humor helps to maintain intraocular pressure and provides nutrients to the eye.

What is the structure of the retina?

The retina is a thin layer of tissue at the back of the eye that contains photoreceptor cells (rods and cones).
