The cornea is the clear window of the eye. It is a dome-shaped clear surface that covers the front part of the eye. The cornea is a vastly structured group of collagen layers and cells and has no blood vessels to sustain and defend it against infection. Tears instead, nourish and protect the cornea.<\/p>\n

There are 5 basic layers to the cornea, from the outside in, epithelium, Bowman\u2019s layer, stroma, Descemet\u2019s membrane and endothelium. The cornea has two main functions. As with a camera, the cornea acts as the eye\u2019s outer lens. It regulates and focuses the entrance of light into the eye and contributes between 65-75% of the eyes focusing ability.
