Wavelengths from 400nm to 500nm are particularly high-energy and can cause damage to the retina of the human eye. Because this spectral range corresponds to that of blue light, it is also termed blue light hazard. In addition to the wavelength of the light, the intensity of the light source, i.e. the light intensity, and the duration of exposure to the retina, also play an important role in blue light hazard.
Interesting:
Usually a person reacts "automatically" to excessively strong, dangerous radiation by instinctively closing the eyes and/or turning away the head. However, in children, the sick and the elderly, this reflex may not yet function or no longer function. If these groups of people can come into the vicinity of a luminaire with RG2, for example in kindergartens, hospitals and care homes, it must be ensured that the minimum viewing distance is maintained.
