New research is suggesting that where your date is looking can indicate whether they are assessing you as a romantic partner. Or if they are just looking for a fun time in the sack.

The new study was published in Psychological Science, and it tracked participants' eye movements when shown non-erotic images of attractive people of the opposite sex. They found that there are visual patterns that concentrate on a stranger's face if the viewer saw the person as a potential romantic partner.

But when it was about lust, participants tended to look more at the person's body.

Yup, lust.

It happens in both men and women. When participants saw young couples interacting, they could tell which were feeling romantic love or lust.

So the next time you're out on a date, look at the eyes. It proves everything!
