corne-, corneo- +
(Latin: horny, hornlike; horny [tissue] pertaining to the cornea, the horny transparent anterior portion of the external covering of the eyes)
cornea
The clear front window of the eyes that transmits and focuses light into the eyes.
Although the cornea is clear and seems to lack substance, it is a highly organized group of cells and proteins.
Unlike most tissues in the body, the cornea contains no blood vessels to nourish or protect it against infection. Instead, the cornea receives its nourishment from the tears and aqueous humor that fills the chamber behind it.
The cornea must remain transparent to refract light properly, and the presence of even the tiniest blood vessels can interfere with this process.
To see well, all layers of the cornea must be free of any cloudy or opaque areas.
