How to keep salt out of your eyes?

My husband has cystic fibrosis. Whenever he spends the day outside in the warmer months, or even in the colder months if he is active, he ends up with red irritated eyes for days from the salt dripping in his eyes all day. This makes him not want to spend so much time doing stuff together as a family or exercising because he knows it will make his eyes burn. Is there anything you have been able to find to help with this problem? It makes him just want to hide in the house all Summer when I'd really rather we could be out doing things as a family. (We have 3 small children.)
