A stone has hit my left eye, and it is red and painful. What should I do?
You should see an eye doctor promptly, as a stone injury to the eye can cause scratches, irritation, or more serious damage. Gently rinse your eye with clean water or sterile saline (5% sodium chloride), avoid rubbing it, and use a clean, damp cloth for comfort. Do not apply any topical ointments or medications without medical guidance.
