By looking someone in the eye, you can understand many things. Ranging from emotional security, to other signs such as sadness, anger, or happiness. What is probably unknown to you, is the fact that the eyes are a signal that speaks to your intelligence and your IQ! 

Which is to say that with a little attention you can understand how intelligent the person in front of you is. According to one study, people with bigger eye babies are generally smarter than others. 

Usually, the diameter of babies is 2-8 mm and together with the iris they regulate the amount of light that passes through our eyes to protect our retina. It has been proven that the size of the baby eye varies from one person to another and not only that, but it depends on the change of emotions. No wonder it is said that when we are attracted to someone, our eyeballs expand.

In terms of intelligence linkage tests have been performed showing that the baby eye is linked to locus coeruleus, an area of ??the brain responsible for cognitive functions. The more functional that part of the brain is, the more the baby eye expands. So do not waste time, but study the baby to understand the intelligence of the one in front.
