The transparent, avascular anterior one-sixth of the coat. The cornea acts as the eye's primary refracting medium, bending light rays as they enter. It consists of five primary layers (six, including the Dua's layer discovered in recent years): the epithelium, Bowman’s membrane, stroma, Descemet’s membrane, and endothelium.
