Are you aware there’s a subfield of kinesic communication data designed for vision movements and conducts referred to as oculesics?  It pertains to several conversation symptoms including direct eye-to-eye contact, averting one’s gaze, pupil dilation/constriction, and number of flashing. These types of traits can build how some others experience you, therefore eye-to-eye contact is another portion of nonverbal nonverbal communication that people should always be much more aware of in friendly relationships.
The best sort (direct/indirect) and lifetime of eye contact depends upon numerous things, like for example educational environment, variations in power/authority/age within the couples involved, and communications perspective. Research shows that variations in the results of eye contact become specifically distinguished when you compare East Asian and Western European/North US countries.
