How often do you consciously notice the quality/beauty of people's 'limbal rings' -- the (often darker) borders between the colored irises and the white scleras of their eyes?

Interesting how most colored contact lenses create stronger limbal rings (darker around the edges)

The rings fade with age, right? so are important for beauty

Yep, I think they're signaling something; not quite sure what yet. Kids also seem to have pretty strong limbal rings, so it might be a general health/fitness indicator (e.g. to get a little more parental investment) rather than just sexually selected to attract mates.
