How do eye doctors test the pressure in the eye?

In brief: Several ways

Basically the surface of eye is temporarily numbed and the "bounce" of the eyeball is measured by applying some external pressure to it attached to a pressure measuring device, similar to pumping a bike tire.
A healthy eyeball has some normal "give" to it. But when pressure increases inside the eye, that "give" is reduced and eye gets stiffer and harder...Good for soccer balls, but not eyeballs.
