Topic Overview
It's not uncommon for a speck of dirt or a small object, such as an eyelash or makeup, to get in your eye. Usually your natural tears will wash the object out. Objects may scratch the surface of the eye (cornea) or may become stuck on the eye. If the corneais scratched, it can be hard to tell when you have gotten the object out, because a scratched cornea may feel painful and as though something is still in the eye. Most corneal scratches are minor and heal on their own in 1 or 2 days.
See an illustration of the eye.
Small objects traveling at a high speed or sharp objects traveling at any speed can cause serious injury to many parts of the eyeball. Injury may cause bleeding, a change in the size or shape of the pupil, a film over the eye lens, or damage to the inside of the eyeball. These objects may become embedded deep in the eye and may require medical treatment.
Objects in the eye can be prevented by using protective eyewear. Wear safety glasses, goggles, or face shields when working with power tools or chemicals or doing any activity that might cause an object or substance to get into your eyes. Some professions, such as health care and construction, may require workers to use protective eyewear to reduce the risk of foreign objects or substances or body fluids getting in the eyes.
