Just had a horrible contact Lens moment. I've started using Air Optix (without incident for a couple of months) and started on my new pair. My astigmatism eye one felt strange and scratchy from the minute I put it in, so I tried to take it out again, but couldn't. I ended up looking in the mirror only to discover it had “vanished” On closer inspection it was way up at the top of my eyeball, in a crumple.
Ok, so I was a bit freaked out. I am sure I put the lens in the correct way, ie not inside out, I probably didn't try to take it out the correct way though (I sort of slid it across my eye and hoped it would come out of the far corner, but it didn't) but what is really bugging me is its finishing place. Could it have gone behind my eye, got stuck etc? or am I being a bit silly 
Is this a common occurrence? (I've only just started using lenses)
Thank you in advance
Answer:
Contact lens can not get stuck behind the eye ball but can get caught up behind the eye lid.
To get it out, either flip the eye lid and take it off the lid or move it around and down to the bottom then take it out.
This has happened to me a couple of times but don't worry, the lens can only get lost if it comes out and lands on the floor, or your arm, or your cheek ……

Answer:
It's not possible for a contact lense to get stuck behind your eyeball. The worst that can happen is it slides up under your eyelid (this has happened to me a few times), but if you curl your eyelid back you can remove it easily.
Answer:
Yeah happens to me all the time, nothing to worried about, soon you'll just be wacking them in your eye in 2 seconds. If this happens again just open your eye real wide and pull it out
