What is cornea?
The Cornea is the front clear window at the very front part of eye.It is highly specialised structure that gives strength & protection to the eye and prevents any bacteria from entering the eye.The other important role it fulfils is to focus the light,it provides two thirds of the focusing power of the eye.The clarity of the cornea is critical for vision.If cornea turns cloudy,you are looking through misty window.
