Cover both eyes and have someone take you to an eye doctor or emergency room if something is imbedded in the eye. Don't rub your eye. Wash your hands before touching your eyes. Visually locate the object in the eye. Pull the upper lid over the lower lid and roll the eye.
Chemical burns to the eyes are a medical emergency.
Hold your head under the faucet or pour water into your eye from a clean container. Keep your eye open during the flushing. Vision can be threatened by foreign bodies, trauma, infection, or exposure to chemicals or particulate matter such as dense smoke. Guard your sight. Protect your eyes with safety glasses.
