The cornea is a part of the eye that covers the front portion of the eye's surface. It protects the eye and helps to focus the light that enters the eye. When we talk about our eyes or eye health, the term 'cornea' may be used. For example, an optometrist or ophthalmologist may examine your cornea during a routine eye exam or prescribe a special contact lens to treat a corneal problem.
