Corneal epithelium that keeps the eye moist and healthy. The cornea accounts for 65 to 75 percent of the overall focusing capacity of the eye. No other tissue in the body depends more on the composition and organization of the extracellular matrix ECM for normal structure and function than the corneal stroma. This layer is constantly being replaced by new cells that migrate from the edges of the cornea.

Along with the sclera. Recently a layer of cornea which is well defined acellular. Bowmans layer helps to avoid the occurrence of corneal scratches. The main function of the corneal epithelium is to protect the eye from infection and to keep the eye.
