Eye Injuries - Topic Overview
A foreign object in the eye, such as dirt, an eyelash, a contact lens, or makeup, can cause eye symptoms.
- Objects may scratch the surface of the eye (cornea) or become stuck on the eye. If the cornea is scratched, it can be hard to tell whether the object has been removed, 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.
- Small or sharp objects traveling at high speeds can cause serious injury to many parts of the eyeball. Objects flying from a lawn mower, grinding wheel, or any tool may strike the eye and possibly puncture the eyeball. Injury may cause bleeding between the iris and cornea (hyphema), a change in the size or shape of the pupil, or damage to the structures inside the eyeball. These objects may be deep in the eye and may require medical treatment.
In the case of a car air bag inflating, all three types of eye injuries can occur. The force of impact can cause a blow to the eye, foreign objects may enter the eye, and chemicals in the air bag can burn the eye.
Eye injuries can be prevented by using protective eyewear. Wear safety glasses, goggles, or face shields when working with power tools or chemicals or when 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.
After an eye injury, you need to watch for vision changes and symptoms of an infection. Most minor eye injuries can be treated at home. See Home Treatment for first aid measures.
Check your symptoms to decide if and when you should see a doctor.
