Expensive sail last night.. 
I have never broken gear ( probably because Im a lightweight ) but for the first time ever the board speared into the back of a wave resulting in a catapult. I restarted & sailed off & then realised I'd left my prescription sunnnies at the bottom of the lake.
I had them tied on with one of those black felt ties but I don't think it was as tight as I could have had it..
I wonder whether it would be safer to use the standard string type glass holders & then tie the string to the wetsuit tag so if they fly off they are still attached to the wetsuit..or would the string attachments slip off with force..?
I found the standard cords or rubber holders always slip off.
I'd tie the cords with couple of rolls of transparent tape for safety.
For floatability, I'd tie a floating thing of sorts, like a cork or something. Tying to the wet don't work, esp. if you freestyle - too much motion. If the leach is long, then it gets in the way.
Ironically, since I had surgery, I don't tie the cheap 20$ pairs I now wear... and never lost one. Sort of a counter-anti-Murphy's law...
I use the neoprene holders that slide over each arm of the glasses. If the wind is quite strong I'll wear a gath helmet that really keeps the glasses secure.
You can get neoprene holders that have a float attached for watersports.
I have put a loop of wire over the neoprene where it goes over the narrow part of the arm and fastened it with a crimp to make sure the neoprene doesn't slip off.
sboardcrazy, feel for you loosing prescription sunnies
When I purchased mine, the supplier sold me the safety strap that has the snake type ends, fitted over the arms. They wont come off.
He then recommended, when I use them, to twist the strap behind neck once, then drop the loop over my head, so the strap is around the front of neck. This way if they get forced off back side, they stay on, and same if forced over the front side. The loop stops them coming off. 
Just remember when you go to take them off, the loop is at the front
Oh, and wear a helmet, saves sunnies, skin damage and head impacting hard bits.
Some good tips.pity they are a bit late!I usually do wear a helmet but as the weather is warming up I stopped wearing it..

What are these..?

thats what i was using but I think i got a bit blase and didnt bother to have them as tight as usual..I rarely catapult...
I dont bother with glasses and simply keep my eyes shut tight, especially when going out through the waves
I use plastic glasses. Much cheaper and no biggy if you lose them. Losing the drink is still a bummer though.
I sussed out cheap sunnies at the optometrist & you can buy tinted goggles for watersports in set increments .They are only $40 & she said she could order some in in a script close to mine .It sounded like you could get each eye a different strength although there are only .5 increments..bit daggy but they are anti fog & look secure & comfortable so i might get a set of sunnies for driving & the goggles for sailing..It won't wreck the image as I look pretty daggy with the fluoro vest anyway..

Good way not to be scared of the big ones! but not much fun if your eyesight is as bad as mine..pretty boring when everything is blurry..
Prior to learning how to windsurf last year, I'd regularly do the mini Gatorade triathlon's in Melbourne. Hardly iron-man stuff - quick dip, 10k bike, gentle jog - nothing too strenuous. Whilst I really enjoyed them, I used to hate the messing about with putting contacts in to get me to the start line for the swim, ditching them for prescription goggles and then changing again to prescription sunnies for the bike/run. I was like a zombie trying to find my bike - banging into marshals etc. I actually lost my bike once after the goggles steamed up on one of those killer hot mornings in Jan/Feb. So - Intralase surgery. Best money I ever spent - no more prescriptions, pays for itself and absolutely no pain/side effects. Back to work the following day in fact. 5 years in and still perfect vision - now recognised as a low risk procedure.
have used lots of different straps, etc , but found that the long neoprene tubes work best.
in Fact they give a nice big contact surface to the spinnaker sheet when your gybing on the Swan River, singlehanded, in a 31' schooner. the new glasses with $600 Ziess lenses went straight into the river, so now I know to tie the neoprene to the lifejacket at least.
. Reminder to self. If you are stupid enough to sail a 2masted yacht down the river, and then hoist a staysail(spinnaker). make sure you take some spare glasses
When returning back up the river , there were voices from boats thet I didnt eeven see after they'd yelled abuse
did the gath helmet sun glass thing for 4 hours yesterday with some good stacks and didnt lose them once, although came close to the end of my nose a few times. good call.

Nice cheap ideas..Feel silly I havent thought of them myself! Still Im a bit hesitant to use my $500 mutifocal transition lens glasses out there just in case ...
but not much fun if your eyesight is as bad as mine..pretty boring when everything is blurry..
I was sent a device for this once - I think free with a Freesail subscription. Think it's called a 'doggle'. It's made from the same material as a rash vest so is light and soft. A simple loop that attaches by velcro around your neck with a separate loop at the back. You can loop your cap or sunnies strap through the loop at the back. If they come off, they're still attached to your neck.
Tried to Google but no luck. Would be easy to make though. I'll try to dig it up and post a photo.
