I wear contacts in triathlons. My goggles leak, but I'm not too bothered. However, if this is part of the healing process after eye surgery I think I'd listen to the doctor... And you are most certainly going to meet a foot or an arm out there, I've never not been kicked or hit, but fortunately I've never had the goggles kicked in my eyes, the nearest has been my chin. It's waiting to happen though!
