You should be fine, but the simulator(ish) ride makes really sudden movements both completely turning up and going almost all the way down. It also bumps a lot to the left and right. I did not have glasses when I was there last month. (Just got a pair yesterday actually). I would get a strap. You don't want to miss any details on the way through the castle or on the ride. You should be safe, but the bumps would have me worried.
