I also have a droopy eyelid (ptosis). In fact one of my eyes is nearsighted and the other is farsighted; and they each have a differently angled astigmatism. Actually, there is no part of my body that is symmetrical. Even my fingers are different lengths in each hand.
I question the premise - I don’t think any of those men look ‘sinister’ when I cover their right sides up on my monitor. Sure they look different, with droopier eyes. And the contrast with the ‘bright eyed’ side is striking. But even if they all had two droopier eyes they’d just look like people. Perhaps slightly less attractive or engaging people, but not sinister or ‘evil’
