I'm not eligible for Lasik, so I wear the dailies. They are pretty expensive if you wear them everyday, but I wear glasses when I'm not surfing so the cost isn't too bad. As has been said, definitely take them out soon after you are done. I also put a couple of the rewetting drops in my eyes before taking them out. Otherwise, they can really stick to your eye after getting dry from surfing which can make removing them pretty unpleasant.
The problem of contact lenses has been solved long ago: Ocufilcon D 45%. 55 % water. Just pop the lenses in and wear them for like a year or so between cleanings and you'll be fine. If you get stink-eye (this may be more frequent at some beaches and during certain seasons), just wash your eyes out right away. Maybe some ice cream cones or water or champagne or whatever. Whatever gets the crud out! Then wash the lenses - I still use those little protein-dissolver tablets sometimes. Beware of your lenses getting rough on the surface. If so, find out if it's 1) wear or 2) protein deposits. If it's wear, you may need a new set of lenses (they're only like 13.95 a pair if you go with the Premier 55's I mention below).
For those of you who need a new type of lense, try these, they are sold by Coopervision:
Biomedics Premier 55. They come with UV-blocking. There are probably 50 different lenses that will work but
these are aspherics for those of you who have some astigmatism. And they are generally thinner than other
types of lense. Almost everyone who tries these, likes them. They recommend taking them out at night but I wear mine for about a year before removing them. The only real problem is when I accidentally get stink from the ocean in them. Just be careful about the stink. Treat your eyes right away when this happens.
Eventually, you should find a lense that works for your eyes. And don't be afraid to take a little squeeze bottle of water and wash your eyes out once in a while. Your eyes will feel great.
Anyways, this works for me. I have no idea why my lenses don't fall out of my eyes, other than I don't open my eyes much when they're near the water. You may need goggles sometimes but I know how hard it is to keep the goggles from coming off - next to impossible. So you may need to have the goggles built into your hood and have a stronger hood. It might take some engineering.
But feel free to wear contacts out there so you can enjoy yourself. You'll get the hang of it eventually.
i wear prescription transition glasses attached with lanyards to my suit or held with a croakie and a squid lid. i have lost three pair in 5 years but i get a new pair each year and they are always an old set. can't see sh!t without em. they fall off but they don't go far ...usually anyway.
I wear contacts, always bring an extra pair with me, and glasses. Mine are bi weekly. If I have worn them for a while, I usually toss them after surfing. Rarely loose them unless I forget to bring backups.
Sorry, just getting back here now: main risks are scratching your eye with sand or some other particle contained in ocean water and the chance of infection...
