Problems with signal lighting colours’ recognition

Summary/Abstract: The article presents the main eye hazards caused by excessive eye exposure on optical radiation. The human eye sensitivity spectral distribution in the context of signal colour recognition was discussed. In order to explain the effects of the mechanism of phenomena responsible for the recognition of signal lights colour, a graphical analysis of spectral distributions of signal lights emitted from traditional incandescent sources and LED sources (light emitting diode) was performed. This analysis also takes into account the conditions under which observation of signal lights may take place (daylight and night vision conditions). The conclusions also indicate the further direction of studies on the influence of colour recognition affected by vision conditions, eye sensitivity spectral distribution (including disturbance of colour recognition) and different types of signal light sources.
