Eye pain, a red eye that is getting worse, light sensitivity, discharge, a feeling that something is stuck in your eye, or a sudden change in vision are all reasons to call. If you wear contact lenses, take them out and leave them out until you have been assessed. Try not to rub your eye, as that can make some injuries worse.
Some situations need hospital care right away. For a chemical splash, a penetrating injury, a severe blow to the eye, or sudden vision loss with other stroke-like symptoms, call 911 or go to the nearest hospital emergency department. For a chemical splash, rinse your eye with clean water while you get help.
