hi, great post.. i remember asking a very similar question at my anti natal classes! ( i wear -5.00 contacts.. so very blind!)

Ok for my 1st bub, i was induced so i was actually asleep and had no glasses or contacts on, and didnt actually realise how quick every thing was going ! they examined me and bubs was crowning already ! so i had DH find my glasses ! and i put them on..

for DS ( 2nd bub) i was more in the know and i left my contact in , no probs.. great to see bubs when he was born ..

I was so worried about popping my contacts out when i pushed, however this wont happen! so dont stress about this at all!!!
