Thanks all - and yes they made it all over safe and sound. Eyes were open in the very next frame before they'd landed.
All in all I didn't see any falls today, though I did hear a few dismounts/falls over the speakers. Thankfully they all sounded like they were minor and horse and rider walked away fine from each.
Soocom nopes this was a bigger event and they already had professionals covering the event (really fancy setup with on-site printing and everything). I also really need to attend more events (so a certain virus has shot those plans apart, esp as most events have now shut down as well) and get more connected. Right now they are nameless faces and horses jumping over things - moving targets for the camera.
Kirk - more likely it got a splash of water on the face as they just went through a bit of water before that jump. So could just be a few drops on the eyelashes causing a bit of irritation.
