What is the Cornea?

 Similar to the windshield of a car or the crystal on a wristwatch, the cornea is a clear structure that makes up the central, outer surface of the front of the eye. It forms a dome-like chamber over the iris (colored part of the eye), pupil (black, circular opening in the center of the iris), and lens – all of which are inside the eye. Just like a windshield, if the cornea becomes cloudy or opaque, it can significantly limit a patient’s vision.
