|Part of||Front of eye|
The cornea is the front part of the eye. It is the clear transparent section of the eye. The cornea covers the iris, pupil, and the eye chamber. It is a special form of tissue. The cornea is clear and has no blood vessels. It has nerves, but 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 does not get through it.
