Eye Anatomy and Disorders

Front

What is the function of the cornea?

Back

The cornea is the transparent front part of the eye that covers the iris and pupil, helping to focus light onto the retina.

Front

What is the role of the lens in the eye?

Back

The lens is a transparent structure that changes shape to help focus light onto the retina, allowing for clear vision at various distances.

Front

What is the pupil and its function?

Back

The pupil is the opening in the center of the iris that regulates the amount of light entering the eye by contracting and dilating.

Front

What is the optic nerve?

Back

The optic nerve is a bundle of nerve fibers that transmits visual information from the retina to the brain.

Front

What is the retina?

Back

The retina is the innermost layer of the eye that contains photoreceptors (rods and cones) responsible for converting light into neural signals.

Front

What is the sclera?

Back

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

Front

What is the vitreous humor?

Back

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

Front

What is the choroid?

Back

The choroid is a layer of blood vessels between the sclera and retina that provides nutrients and oxygen to the eye.

Front

What are rods and cones?

Back

Rods are photoreceptors in the retina that detect light and dark, while cones detect color and are responsible for sharp vision.

Front

What is the iris?

Back

The iris is the colored part of the eye that surrounds the pupil and controls its size, thus regulating light entry.
