Female Leader here, and I do use eye makeup and false eyelashes. Whether I’m Leader or Follower, I take off my glasses. But I can still see fine on the dance floor. I used to sometimes wear contacts, but then it was a hassle to have to keep a pair of readers handy so that I could check my heat list or assist others with their hooks-and-eyes or pinning numbers or whatnot.
I have a female amateur partner who wears glasses, and she wears them when she competes (she’s a Follower), and she does not wear eye makeup. We’re syllabus competitors and honestly, I don’t think it’s made any difference to our scores. I’m pretty sure she wore them the last time she competed with her Pro (again, syllabus) and I don’t recall anyone thinking that glasses affected her scores.
So, as others have said, weigh the pros/cons and make your decision. Then go out and dance well.
