Foreign object in the eye

A foreign object in the eye usually enters from outside the body. It can range from dust or even a metal shard and these do not naturally belong there. Once a foreign object enters the eye, it will surely affect the structures such as the cornea or the conjunctiva. The cornea is best described as the clear dome that covers the front surface of the eye. It functions as a protective covering for the front of the eye. The light enters via the cornea and helps focus light on the retina at the back of the eye.

The conjunctiva is the thin mucous membrane that envelops the sclera. Take note that the conjunctiva runs to the edge of the cornea as well as covering the moist area beneath the eyelids.

Nevertheless, some types of foreign objects can lead to infection or damage the vision. Always remember that a foreign object that lands on the front part of the eye will not go behind the eyeball.
