What is the cornea?
Human bodyVision
Quick Answer
The cornea is the clear front surface of the eye. It helps focus light onto the retina and protects the eye from dust and germs.
The Full Story
The cornea is a transparent dome-shaped layer at the front of the eye. It provides much of the eye’s focusing power by bending incoming light before it reaches the lens and retina. Because it must remain clear, it contains no blood vessels; it gets oxygen mainly from the air and nutrients from surrounding fluids. Injury, infection or disease affecting the cornea can significantly impair vision.
