Light and health are closely connected. In our everyday lives, we are almost constantly being exposed to a variety of artificial light sources. It starts with simple ceiling lamps to the displays on smartphones and televisions and, in some rare cases, may even extend to high-power lasers. While light can even promote well-being when used properly, incorrect use can have the exact opposite effect in the worst case scenario. The consequences span from harmless, temporary phenomena such as glare or even severe, chronic damage to the eyes and skin.
In the medical and cosmetic sectors, one faces the special challenge that, on the one hand, (laser) light sources have to be intense enough for certain applications in order to modify tissue (e.g. including selective destruction!) and, on the other hand, patients and staff or other persons shouldn’t be exposed to the risk of unintended injury.
In cooperation with the DKE Work Group 812.0.1 “Lasers in Medicine”, the DKE Joint Committee 841 “Optical Radiation Safety and Laser Devices” is doing the necessary standardisation work so artificial light and laser sources in all areas of life are safe and controllable and benefit people.
