This is on the grounds that the sclera (the "white" of the eye) somewhat covers the top and lower part of the front cornea. The level distance across of the cornea normally gauges around 12 millimeters (mm), and the upward breadth is 11 mm, when seen from the front. However, whenever saw from behind, the cornea seems roundabout, with a uniform measurement of around 11.7 mm. This makes the cornea around 66% the size of a dime. The middle thickness of the normal cornea is around 550 microns, or somewhat the greater part a millimeter. The cornea has five layers. From front to back, these layers are: The corneal epithelium. This external layer of the cornea is five to se...
