My friend and I work together in a kitchen where we wash dishes. There is a power washer of sorts, a hose really, to help us get off my stubborn food items from dishes. Today it slipped out of my hand and sprayed my friend in his eye. It was very painful for him for a brief time, then the pain subsided within an hour. His vision is still cloudy though. We don't have medical attention right away. Is there any way to know that it will likely be OK? There is no bruising in his eye, looks normal
