No issues before. Sometimes, if I'm having general eye discomfort due to allergies, I'll throw my glasses and an pre-filled contact case in my bag just in case. Think I might have switched contacts to glasses in the evening once, but it wasn't due to any rides. My eyes were just irritated in general. I've gotten splashes in the face from Splash Mountain, kept my eyes open on fast rides, and never had any problems. I wear soft toric lenses.
I've actually been going through a bit of eye irritation the last couple of weeks and haven't been able to wear my contacts. Leave in a little over 3 weeks for my next Disney trip and have decided it's time to have someone look into the eye irritation in the hopes it will resolve before the trip so I can wear my contacts and sunglasses. I know I'll be super frustrated if I have to wear glasses full-time for the trip.
A recommendation, if you haven't been wearing contacts lately, make sure you get them soon so you've got some time to build up the number of hours you can tolerate wearing them. If you haven't used contacts in a while, it's hard to go from zero to 16+ hours a day immediately.
