[Effects of optical radiation in ocular structures].

The eye and the skin are organs that are particularly vulnerable to external aggression, such as electromagnetic radiation- meaning ultraviolet radiation, visible radiation (especially blue light) and infrared radiation. The three mechanisms involved are: the photo-thermic mechanism, the photochemical mechanism and the photomechanical mechanism. The effects of such exposures can be either temporary or permanent, if inadequate protection occurs. Today, there are enough data so that special protection measures can be taken concerning the potential damage of optical radiation. Among those, we mention artificial implants or sun glasses containing UV filters or surgical gestures that can be taken to protect the eye against the surgical light. Ultimately, the effects of optical radiation upon the eye are related to being well informed about the risks of uncontrolled exposure and the protection measures against it.
