Which description correctly identifies the sclera?

Which description correctly identifies the sclera?

• A. The clear lens of the eye
• B. A transparent jellylike tissue filling the eyeball
• C. Tough, white outer coat of the eyeball
• D. Light sensitive cells that respond to color

Answer: (C)

Think about what the sclera is like and what its role is. The sclera is the tough, white outer coat that protects the eyeball and helps give it its shape; it also anchors the eye muscles. That description lines up exactly with what the sclera is, making it the best match. The other descriptions point to other parts of the eye: a clear front surface that helps focus light is the cornea, the jellylike filling inside is the vitreous humor, and the light-sensitive cells are the rods and cones in the retina.
