What Your Eye Symptoms May Mean
Tiny blood vessels in your eye may expand or burst when they get irritated or infected. It's pretty common and often goes away without treatment. An injury, glaucoma, and cuts, scratches, and sores on your cornea could be more serious. Check with your eye doctor if your eye hurts or doesn't improve in a day or two, or if you have trouble seeing.
