title: [Eye and ultraviolet light].
abstract: All the ocular structures, from cornea to retinal layer, can be damaged by exposure to the light radiations. Acute keratitis combined with conjunctivitis will result from an intensive photic exposure. On the other hand, pterygion more likely represents the consequence of chronic exposure to the ultraviolet rays. Exposure to the ultraviolet rays has been involved in the appearance of the typical yellow pigments of the nuclear cataract. Indeed, the physiopathological mechanisms are now progressively better understood. The progression of retinal degenerations might be influenced by uncontrolled exposure to ultraviolet rays, particularly during childhood. It is therefore useful to protect the eyes against ultraviolet sunrays. Filtering glasses seem to be one of the most effective ways to reach that objective.
