Eli5: How does it come we notice when we get direct eye contact with another person?

There is something that makes you know when you have that direct eye contact with a person, even though they might stand meters away from you and you are surrounded by other people too.

What makes you know when you have that eye contact? Because even if there is someone that is standing almost right behind me I know when someone that is standing let’s say 6 meters away is looking at the other person or when they are looking at me.

It’s a natural behavior. Before we developed such complicated mating ritual (such as buying coffee, offering flowers, going to a restaurant etc) and before we could talk, prolonged eye contact was a sign of interest. As such, prolonged eye contact is ingrained in our instinct as something important.

Second thing to understand, our eyes see everything in front of them. Not just the bit we’re looking at. It’s just that our brain chose to ignore things beside the center because it can’t keep up with giving high definition to everything we see. Nonetheless, it still check everything for any sign that are important to it (movement for predators, shiny stuff, etc) which include eye contact. When the brain discern that eye contact, it attract or attention to it.
