The cornea is the transparent, clear layer at the front and center of the eye. In fact, the cornea is so clear that one may not even realize it is there. The cornea is located just in front of the iris, which is the colored part of the eye. The main purpose of the cornea is to help focus light as it enters the eye. If one wears contact lenses, the contact lens rests on the cornea.
