Eye injuries have a number of different causes, such as a blow to the eye, foreign bodies, lacerations (cuts) and ultraviolet light.
Eye injuries can also be caused by chemical exposures and burns as a result of liquid being splashed into the eyes.
Some aerosols can be harmful to the eyes, including Mace (attack defence spray), tear gas, pepper spray and some chemicals in hair spray. Chemicals can also be transferred from the skin on your hands to your eyes.
