i know this sounds remarkably stupid, but i'm a contact lens wearer and i have my fingers contained by my eyes relatively often.
a short time ago wondering, what kind of touch related nerves are surrounded by there? You ask an interesting interview. The iris/pupil area that you are referring to is in actual fact your cornea (the iris and pupil are located a few millimeters behind your cornea). There are nerves surrounded by the cornea and in the rest of the front of the eye. Being poked anywhere contained by the eye typically hurts. One reason you may not perceive 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 spasm increases. You want to be sure that your contact lenses are transmitting enough oxygen so that the nerves within the cornea aren't becoming anesthetized. See your optometrist or ophthalmologist yearly to evaluate your contact lenses and the overall strength of your eyes.
There are no nerves in the sclera.
