Why does it feel so good rubbing your eyes, then hurt as soon as you stop?

Awesome question; most don't stop and think about these things! 

So basically, **Unmyelinated nerve fibers** are found in the **dermis**, or commonly known as sensors in the skin. When those sensors are irritated, it is called an itch. Itches are signals to our selves that something is wrong and it should be checked out immediately. The sensors in the eye and most mucus membranes are very very sensitive. So it is easy to cause tiny scratches or abrasions in the top layer of the skin. When you rub your eyes, the brain is satisfied that the problem was investigated, but consequently causes small cuts that get irritated more when its exposed to air!
