I had eyelid surgery several years ago. My eyelids were starting to lay on my eyelashes and interfere with my vision. It was medical but I'm not going to pretend I wasn't glad to get a bit more eye back. I don't know about other people, of course, but my natural eyelids have no fold in the center (think Catherine Zeta-Jones and you have pretty much got my eye shape). As the skin on your face begins to settle, so do your eyelids. People like me who have extra fat there get the droops as they age.

Because my procedure was a medical one, it was more invasive and permanent than a cosmetic eyelift (it was no fun; I couldn't open my eyes for days but everything healed well). The doctor said eyelifts have to be redone fairly regularly. What he did should last 20 years.
