I had my glasses on during labour for most of the time except for when I was in and out of the bath and shower - and I remember asking DH about 5 times and getting the midwife who was with us to check that he had my glasses with him when we went off to have the c/s! As soon as she was born I got them to put my glasses on - (Im VERY shortsighted ) so I could see him and her after she was born. I had them on in recovery and during our first skin to skin and breastfeeding time. I didnt notice them fog up or bother me - I was a bit too in love although I hate my first pics with them on - I wear contacts everywhere except at home!
Good luck!
