It's about contact lenses.

How could they possibly stay in if you swam in them and opened your eyes underwater? Speaking as someone who used to wear them.

They can stay in, I haven't had problems with them staying in and I only tend to use them when I am swimming. I use disposables so they're usually tossed later in the day.

If you soak them and clean them like you usually do than you should be fine. I used to use yearly soft contacts and I used to be able to do that. I didn't do it often mind you. Just be careful. My optimist always warned about swimming with contacts. That is why I use dailys. If I lose one it isn't a big deal.
