Saline is what you are supposed to wash your eyes out with when you get something in them in addition to being what contacts are stored in every night

Saline is isotonic and, short of a large electrolyte imbalance, shouldn't cause any/very little irritation to your eyes. And if you're hyponatremic to the point of saline solution causing eye irritation, you have much more immediate and life threatening problems to attend to than risnsing your peepers out
