Everyone reacts differently to the prospect of making a favorable impression on someone they find attractive, and some people end up more nervous than others. However, while degrees may vary, nervousness itself is a common factor. After all, it is not easy to face judgment and the possibility of rejection by someone you already like and are eager to get to know better. You may well have spent hours thinking about how to make a great first impression.
There are so many things to think of: how you dress, your behavior and 
body language, how you carry yourself, how you start a conversation, what you talk about…the list doesn’t seem to end. It is really confusing, right? Apparently not, if recent research is to be believed. Body language experts claim that now there is science to back up the age-old phrase, ‘it is all in the eyes.’ Evidence suggests that eye-contact is the most significant determinant of success or failure on that nerve-wracking first date.
The Key is in the Eyes
Some of you may be surprised to find that the subtle skill of your eyes is a more pressing factor on that first encounter than your personality, how you look and the way you make conversation. However, the good news is 
that with awareness of the right way to go about it, eye contact is a skill you can easily master. So, here are a few tips to help you get it right.
Establish a Bond
The first role of eye contact, especially when you are meeting a new person, is to establish a bond. Don’t be afraid to look into their eyes. A confident gaze will not only create a good first impression, it will also give a clear signal that you are interested in the person. However, remember not to stare outright for too long. You don’t want to end up making the other person feel that you are invading their privacy. Short and frequent glances should be the way to go at this stage. If you feel that your looks are being reciprocated, it is a signal that the interest is mutual, and now you can relax into a nice, friendly conversation.
Bring in the Longer Gaze
The role of eye-contact does not diminish in significance after that crucial first step. 
Once you have gotten to know each other a little bit, you have reason to be more free and confident about your eye contact. Maintain it for periods of 5-7 seconds, especially while you are listening to him/her talking. It will show your date that you are earnestly interested in what they are saying, and it will also give the person an opportunity to appreciate the attractiveness in your own eyes. Eye contact for 5-7 seconds may take a conscious effort though, because according to the experts the average time period for which most listeners will maintain eye contact is 3 seconds.
Enhance Your Eyes
With all this eye-contact going on, it is important to feel confident about how your own eyes look. Women can use the opportunity here to put their make-up skills to good use. Ladies, bear in mind though, that the idea is to enhance the natural look of your eyes and not distract the other person with glitter and dazzle. That might just be a turn-off. The ancient cosmetic Kohl, also known as Kajal in the Indian subcontinent, is an excellent product to use on such occasions.
