We assessed health risks for operators who had to live in mobile houses in the Arctic regions. Inadequate lighting is a most significant factor related to housing conditions that can cause various pathologies resulting in decreasing working capacity. We revised data on impacts exerted by luminous and LED lighting on operators and it allowed us to determine reasons for “aftereffects” produced by LED lighting regarding an increase in latency in No. 95 pattern electroretinogram (PERG); this latency characterizes a situation with ganglionic cells in the visual analyzer. We put forward a hypothesis that lower “inhibition” efficiency was caused by absorption of blue light within 380-450 nanometers range, and an increase in PERG P50 amplitude was caused by an additional increase in Na+, Ca+ ions flows when ChR2 protein absorbed excessive 470 nm blue light against a blue light dose in a luminous lamp spectrum. We showed that there were practically no changes in operators’ health after they had been exposed to dynamic LED lighting; however, all the participants in the experiment had a W-like splitting in P100 peak in visually induced cortical potentials as a response to stimuli with different angle sizes...
