When it grows long enough, it can curl back into My Boy's eye.
I really think this causes him to be bothered.
A year ago he had some irritation and head shaking symptoms while wearing a fly mask (which diminished within half a day of the mask being removed.)
I think the fly mask was pushing on this rogue eyelash, poking his eye.
Strange theory, but possibly true?
I noticed this crazy eyelash last summer and now keep it trimmed for him.
What else are mommies for?
