Have you ever been able to swim and dive after having an eye vision surgery? What do you need to pay attention to?
If it's the kind of back oxygen bottle, it doesn't matter. No, swimming is fine. But some people are afraid of water, especially in the sea water, there will be a sense of weightlessness, helpless
In fact, you do not have to swim, but personally think snorkeling can swim, it may be more fun
At a loss, and some people are not accustomed to use the mouth to breathe, accidentally use the nose to choke water, it will panic. Reported the course to study well, when you can dive, also can swim probably ~ my colleague is such!
