Why can’t humans see underwater?

Can your eyeballs fall out?
Not all popped eyeballs come from head trauma. A few people can luxate their globes on purpose, and certain others get “spontaneous globe luxation” when their eyelids are pushed in the right way. Someone with shallow eye sockets or floppy eyelid syndrome, for example, might pop his eyeballs during a regular eye exam.
