Parts of the Eye

Front

What is the function of the retina?

Back

The retina is the layer of receptor cells that lines the back of the eye and is responsible for converting light into neural signals.

Front

What is the role of the iris in the eye?

Back

The iris is a thin structure that controls the size of the pupil, regulating the amount of light that enters the eye.

Front

What is the cornea?

Back

The cornea is the clear, dome-shaped surface that covers the front of the eye and helps to refract light onto the retina.

Front

What is the optic nerve?

Back

The optic nerve transmits visual information from the retina to the brain.

Front

What is the sclera?

Back

The sclera is the white outer layer of the eyeball that provides structure and protection.

Front

What is the vitreous humor?

Back

The vitreous humor is the clear gel that fills the space between the lens and the retina, helping to maintain the eye's shape.

Front

What is the aqueous humor?

Back

The aqueous humor is the clear fluid that fills the space between the cornea and the lens, providing nutrients and maintaining intraocular pressure.

Front

What is the pupil?

Back

The pupil is the opening in the center of the iris that allows light to enter the eye.

Front

What is the lens of the eye?

Back

The lens is a transparent structure that helps to focus light onto the retina.

Front

What is the function of the ciliary body?

Back

The ciliary body is a ring of muscle that controls the shape of the lens for focusing.
