When we visited Universal Studios in Nov. '04, my DH and 8 yr old daughter waited in line for the Mummy ride and when it came time to board, they were told they both had to remove their glasses. Well my DH is totally blind without his specs so he chose not to go and was directed to an exit and my daughter did not want to go by herself so she also missed the ride. They thought there was some sort of inversion in the ride but from reading the boards, I don't believe this is the case. Can anybody tell me why you must remove your eyeglasses?
