I know 2-3 people with beautiful eyes who always state they would want a girlfriend/boyfriend with pretty eyes. They adore the human eye and are fascinated by beautiful eyes. The girl loves playing up her eyes and the guy I know has amazing lashes and eye shape and has the same view ie both very attracted to the eyes of the opposite sex. Why is this?
My wife has green eyes, I don't just brown and she is pissed none of the kids got her colored eyes. One of the reasons someone might want someone with colored eyes is to increase the chances of a child having them. Other than that it's just a preference.
