Wakeboarding with contact Lenses??

My sons wakeboard and are pushing me to give it a try. My big concern (along with being old, bad knees and ankles from football and snowskiing) is the fact I am blind as a bat and the only way I can see anything is with my contacts or my glasses. I know I could not even try wakeboarding without the contacts - I wouldn't be able to see the wake, the boat, etc. So, does anyone wakeboard with contacts and if so, have you ever lost them?? Any advice would be great. Thanks.
