Curious - a question concerning the eye.

Dooga Blackrazor

People are often attracted to eyes; however, do eyes diminish in beauty over time, like other physical attributes? If not, do marriages last longer among couples who both have, according to culture, beautiful eyes?

I do not know of any research about marriages holding longer when the couple has nicer eyes.

But I guess the reason for this is our evolutionary history. Firstly many diseases will have some visible effect on the eyes, so nice eyes signal health. Secondly vision is an incredibly important sense for humans so a partner with good sight gave much higher chances of raising children than one with bad sight (I mean in evolutionary history long ago, not nowadays). Therefore we may all have inherited a preference for anything that signals good sight, which is probably what we nowadays call "beautiful eyes".
