Cornea

The cornea is the circular transparent part at the front and centre of the eye. It is a continuation of the sclera, the white part of the eye. The colour of the eye, the iris, can be seen through it. For the sake of transparency, the cornea contains no blood vessels. However, a pump ensures its relative internal humidity (not unlike a dry sponge). The corneal cells receive oxygen and nutrients from two different fluids, namely, tears (outside) and the aqueous humour (inside). As bacteria and viruses run up against little resistance, the cornea is prone to infection.
