In recently-published research in the Proceedings of the Royal Society B, the Face Research Laboratory at the University of Aberdeen, reported that people judged happy faces more attractive if the face was looking directly at them. However, where it is looking does not affect the attractiveness of a disgusted face. The correlation between gaze direction and attractiveness is stronger for opposite-sex faces than it is for same-sex faces. This is yet another confirmation of the importance your eyes play in making you more attractive to members of the opposite sex, and shows how important it is to be able to direct your gaze freely and strongly at people if you want to make a good impression. However, sometimes our gaze becomes obscured by drooping or puffy eyelids, making it especially difficult to make the kind of furtive but direct eye contact essential to the initial stages of mating. If you are having difficulty connecting with the object of your desire, it might be time to consider eyelid surgery (blepharoplasty). If we want to look young, attractive, and energetic, both to ourselves and to others, the eyes make all the difference.
