Contact us promptly for eye pain, a scratch, redness that does not settle, discharge, light sensitivity, or a feeling that something is in your eye. Contact lens wearers should remove their lenses and call if any of these occur. Hoping symptoms will clear on their own can sometimes allow a problem to worsen.
Some situations need a hospital right away. Call 911 or go to the nearest emergency department for a chemical splash, an object that has penetrated the eye, a serious blow to the eye, or sudden vision loss with other stroke-like symptoms. For chemical exposure, rinse the eye with clean water while help is on the way.
