What is the white portion of the eye known as?

• A. Sclera
• B. Cornea
• C. Retina
• D. Iris

Answer: (A)

The white portion of the eye is known as the sclera. This tough, opaque tissue forms the outer layer of the eyeball and provides structure, protection, and support for the eye. The sclera serves as an anchor point for the muscles that control eye movement and is essential for maintaining the shape of the eye. The other parts of the eye mentioned have distinct functions. The cornea is the clear, dome-shaped surface that covers the front of the eye and plays a crucial role in focusing light. The retina is the layer of tissue at the back of the eye that senses light and sends visual signals to the brain. The iris is the colored part of the eye that controls the size of the pupil and, consequently, the amount of light that enters the eye. Each of these components is vital to vision but serves a different purpose than the sclera.
