i know this sounds remarkably stupid, but i'm a contact lens wearer and i have my fingers in my eyes relatively often.
just wondering, what kind of touch related nerves are in there?
Why doesnt the sclera hurt when poked whereas the iris/pupil does?
You ask an interesting question. The iris/pupil area that you are referring to is actually your cornea (the iris and pupil are located a few millimeters behind your cornea). There are nerves in the cornea and in the rest of the front of the eye. Being poked anywhere in the eye typically hurts. One reason you may not feel as much when you touch your cornea is that you are a contact lens wearer. After wearing lenses for some time, your cornea gets used to touch and your threshold for pain increases. You want to be sure that your contact lenses are transmitting enough oxygen so that the nerves in the cornea aren't becoming anesthetized. See your optometrist or ophthalmologist yearly to evaluate your contact lenses and the overall health of your eyes.
Reply:There are no nerves in the sclera.
