Ever since I shot Powder Blast (?), a citrus based, high pressure cleaner into my eyes, I wear some goggles when I spray my guns. It stung like a son of a gun and seriously wondered if I had really messed up my eyes. A good flushing with water and switching from contacts to glasses that evening squared me away. I rinsed my contacts really good and wore them the next day.
