I was in the same situations as you are right now, when I was sending my application to AADSAS. I answered 'yes' for this question, because I know they won't deny ur acceptance just because you are applying to some other professional school , if your credentials are strong enough. Now, I don't even think I am going to apply to optometry school. I put yes for that answer just because I wanted to keep my options open. I don't see anything wrong in liking more than one profession. If I get an interview from somewhere (ths a big IF there), I can explain them during the interview why I wanted to apply to optometry school.
