"What is it with the eyes of organisms ? Why are we ( not only humans ) compelled to `` look into the eyes `` of others ?"
"Because the eyes reveal where someone ( or something ) is looking . Since we have a narrow range of perception this information tells the looker important information about what we are interested in at that time . Note that many animals do n't look into each others eyes ( most herbivours ; since they have near-360 degree vision , eyes convey almost no information ) , and many animals take different information from them than we do ( cats for example take looking at them as hostile behaviour , and narrowing the eyes and looking away as friendly ) ."
