A study conducted in 1989 assures that simple eye contact could make a person fall in love with you (Kellerman, Lewis, and Laird). 
In this study two opposite sex strangers were asked to gaze into each other’s eyes for two minutes, which in some cases was enough to produce passionate feelings for each other. Eye contact is a powerful stimulator of love and affection. When you look someone directly in the eyes, their body produces chemical called phenylethylamine that may make the person feel in love. If you want to make someone fall in love with you, one of the first thing you should do is to look into their eyes.
Don’t be disappointed if your sweetheart doesn’t meet your gaze – that could be very well because they are overwhelmed by you! In some cases you will find yourself able to look into anyone’s eyes, except the person you really like. Shyness often gets in the way of the intense eye contact — we rarely look in someone’s eyes if at all; it feels uncomfortable.
A British scientist found that people look at each other only 30-60% of the time when talking, leave alone eye gazing. In fact, this creates a highly emotional state similar to fear. Now you need to decide what your next move will be – approach or retreat. So, if you want phenylethylamine gushing through your sweetheart’s veins, look into their eyes more. However, it is important to go slowly, do not make this change in one day, otherwise it will seem unnatural; they will feel like deer eyed up by a lion!
