Hi,
Generally , those who can speak usually communicate with a language. We speak and write to pass our massages.When speaking is involved, the nonverbal signs such as hand gestures,eye-contact, body posture and so forth are too helping to express . Thus , we don't use eyes more than words. But , it helps to express the messages more effectively .
In some situations where speaking are not possible, such as in the library, hospital, run into a pretty girl with a partner beside her.... and so forth, we do try to use eyes and hand gestures to communicate.
Even those who are mute do not communicate with eyes only ,instead they use signs language. Babies who can't speak too don't use eyes to communicate, they cry, laugh, babbling , cooing and body language....
Those who are in love maybe experiencing communicating with eyes more than words??? Ha! Ha! Ha!!!{-:
