Eyesdropping is essentially eavesdropping with your
eyes. When someone looks at something that is not theirs. The
thing that the
person is looking at does not necessarily have to be confidential but it just has to not be theirs like a computer screen or a cell phone.
"Raymond, stop eyesdropping, look at your own computer screen."
"
Liz,
don't you have
better things to do than to eyesdrop?"
