Injury Statistics Approximately 2.4 million eye injuries occur in the United States each year. Of these 2.4 million, more than 40,000 have permanent visual impairment. Over 13% of these eye injuries (over 310,000) result exclusively from sports-related activities. Each year in the United States, eye injuries cost approximately $300 million for work-related eye injuries, which accounts for only one-third of all eye injuries, according to the United States Eye Injury Registry. FunctionsYour eyes contain the receptors responsible for vision, which is the most dominant sense in humans. These receptors or “sensors” receive information about the surrounding environment and transmit this information to the brain via the optic nerve. Your brain quickly processes this information and creates the images you see, which allow you to see stationary objects and track moving objects whether your head is moving or stationary. Your eyes are recessed into the bony sockets of your skull, which provide protection from many types of impacts from blunt and sharp objects. Even though your eyes are largely protected by the bony sockets of the skull, they are still susceptible to frontal injuries because the fronts of the bony sockets are open exposing the eyes. Injuries Your eyes can be injured in many different ways, such as if you are cut or pierced (penetrated) with a sharp object, if you are hit with enough force to cause the eyeball to burst, or if you are moved too far in of the orbit causing rupture of the optic nerve. There are 3 common types of eye injuries: a corneal laceration (a cut or puncture wound), a globe rupture (bursting of the eyeball, and an optic nerve avulsion (complete tear of the optic nerve), each… ... half of paper ......the eyeball, a blunt object hits the eyeball, or the eyeball is moved too far into the eye socket. When a sharp object is pushed against the eye, it deforms the eyeball inward and creates tensions within the tissue. When these stresses are high enough, the tissue tears and continues until the tear completely passes through the wall of the eyeball, at the point of the penetrating (sharp) object. When a blunt object collides with the eyeball, it first pushes and deforms the eyeball inward, further creating stress within the tissue. As the blunt object continues to press on the eyeball, the pressure inside of the eye increases, which causes the stresses within the tissue to increase further. When these stresses are high enough, the tissue begins to tear at the weakest point of the eye wall and continues until the tear completely passes through the wall..
