The cornea is the clear outer layer of the eye through which you can see the [[Iris]] and [[Pupil]].  It has an [[index of refraction]] of 1.376<ref name="Scale Model of Eye">{{Cite web |title=Scale Model of Eye |url=http://hyperphysics.phy-astr.gsu.edu/hbase/vision/eyescal.html |last=Nave |first=R |date=2020-05-25 |website=HyperPhysics}}</ref>, and a curved outer surface, contributing to the [[refractive state]] of the eye.  The Cornea provides about 80% of the eye's total refracting power.  If you have [[LASIK]] or [[PRK]] surgery it thins the cornea to change your refractive state.
