Whitewater rafting with glasses

[KillerCharlie]

Has anyone here with glasses gone whitewater rafting? I have an old pair, but I'm terrified they'll fall off since my vision is about 20/1000. Are there good straps I can order online somewhere to keep them glued to my face?

I found this website that has some different types of prescription goggles/glasses that are made for water sports when I was looking into what surfers with poor eyesight use.

However most surfers just wear disposable contacts and will close their eyes when they go under water so they don't come off.
