|Gray's||subject #225 1070|
The cornea is the front part of the eye. It is the clear transparent section of the eye which that covers the iris, pupil, and the eye chamber. It is a very special form of tissue because the cornea is clear, has no blood vessels, and has nerves with no myelin sheaths on them.
Dua's layer is a newly discovered layer of the cornea. It was described in June 2013. It is the sixth layer of the cornea to be discovered. Despite its thinness, the layer is very strong, and air cannot get through it.
