If you want to 'clean' your eye, this is possibly one of the world's worst ways to go about it.

A percentage of the population find "spontaneous globe luxation" or eyeball popping relatively easy, and a strong sneeze or exhaling while holding their nose can result in a 'popped' eyeball.

Luckily, getting the offending ocular instrument back in its hole is a relatively simple surgical procedure, although it must be done quickly, and in a sterile environment. Best not to test it, we think.
