I broke my helmet on a really stupid fall crossing a wet pedestrians bridge (my bad for not obeying the 'get off your bike' sign, too), about 2 weeks ago.
I began bleeding and got my eye almost shut close by the swelling. Luckily, it was just a few blocks away from my destination, so as soon as I arrived, they sent me to the ER and were kind as to store my bike. My Aeon helmet actually took most of the hit so I guess it saved my face (and specially my eye) from a much more serious injury. It's still structurally functional I think, so I'm going to keep on using it for now, as it is an expensive helmet (even though it will have to be replaced, eventually). In any case I leave a picture, if anyone has opinions on the condition of the helmet:
