Water hitting your eyes with force, can be very painful.
Couple that with wearing contacts, and you will feel alot of pain. I've had contact lenses push back behind my eyeball. It's very painful, whilst you're trying to roll your eyes back to drag the lense out, or draw it out some way.
I usually have to roll my eyes way back, till my hubby can see the lense, then he drags it down and out.
Not sure I could make it to an A&E in time. The pain would be unbearable.
At least she had fast help on hand.
