Eyelids help protect your eyes—when you blink, eyelids spread moisture over your eyes. Blinking also helps move dirt or other particles off the surface of the eye. Like most other parts of your body, your eyelids can get infected or inflamed. Eyelid problems are common but rarely serious. Tell your eye care specialist about any problems you are experiencing with your eyelids.
