Eye

The eye is the organ of sight, a nearly spherical hollow globe filled with fluids (humors). The outer layer or tunic (sclera, or white, and cornea) is fibrous and protective. The middle tunic layer (choroid, ciliary body and the iris) is vascular. The innermost layer (the retina) is nervous or sensory. The fluids in the eye are divided by the lens into the vitreous humor (behind the lens) and the aqueous humor (in front of the lens). The lens itself is flexible and suspended by ligaments which allow it to change shape to focus light on the retina, which is composed of sensory neurons.

Foreign Objects in Eye

Foreign objects in the eye usually are flushed out through the natural blinking and tearing action of the eye. If the foreign body can be seen on the inner surface of either the lower or upper lid, try to gently flush it out with water or use a cotton-tipped swab to invert the eyelid and inspect the underside. Seek medical attention if the foreign body cannot be removed, or if there is still discomfort or blurred vision after removal.
