Overview. Eye contusion is a bruise around the eye. It may involve the eye, eyelid, eye socket, and associated muscles and is usually the result of a blunt injury to the eye.
The eye and its contour: a very sensitive area. Very thin, scarcely protected and naturally subject to numerous aggressions, the eye contour is one of the most sensitive parts of the face. For the eye itself and the contour, gentleness is crucial. The eye's surface has a sort of natural shield against various external aggressions (irritants, dust, etc.): lachrymal liquid. Composed notably of organic salts, glucose and oxygen, it nourishes the surface layer of the cornea.
