I learned about this in health class or something like that back in middle school and have turned it into a nice routine when the conversation gets stale.
When you notice a girl looking a certain way, you can make a comment about it or even know if they are telling the truth or not.
if she is looking...
UP AND TO
YOUR LEFT... she is trying to visually imagine something
UP AND TO YOUR RIGHT... she is trying to visually remember something
TO YOUR LEFT... she is trying to imagine a noise
TO YOUR RIGHT... she is trying to remember a noise
DOWN AND TO YOUR LEFT... she is trying to remember a smell, feeling, or taste
DOWN AND TO YOUR RIGHT... she are probably talking to herself
you know if they are lying if...
for example, you ask her if she can remember if she yelled at anyone lately.
if she says no (and is telling the truth, she should be looking either to your right or up and to your right) but is lying, she will look either to your left or up and to your left.
*** Looking straight ahead or with eyes that are defocused/unmoving is also considered a sign of visual accessing.
*** A typical left-handed person would have the opposite meanings for their eye-directions.
