The Effect of Light and Color on Human Physiology in workplace

Safety working environment requires not only workplace with sufficient light, and also rational direction of the light, the lack of harsh shadows, causing glare.

Proper lighting and painting equipment and hazards allows to watch them more closely (device painted in solid color), and the warning coloring hazards will reduce injuries. Besides selecting the right combination of colors and their intensity will minimize the time to adapt the eye when looking to the details on the work surface. Choosing the right color can affect the mood of the workers, and, therefore, the productivity of labor. Thus, the underestimation of the influence of light, the choice of color and light lead to premature fatigue of the body, the accumulation of errors, lower productivity, increased marriage and, as a consequence, to injuries. A disregard for the coverage due to the fact that the human eye has a very wide range of accessories: from 20 lux (full moon) to 100,000 lux.

Color and light are interrelated. Coloring of equipment, materials and other to black oppresses workers. When carrying the standard boxes of black and white colors all workers declared that the black boxes heavier. Black thread on a white background can be seen at 2100 times better than white on black, there is a sharp contrast (brightness ratio). With the increase in brightness and lighting up to certain limits visual acuity and brightness increases, and eye can separate items, i.e. speed discrimination. Too bright light adversely affects the eyes, causing blindness and pain in the eyes.

Incorrect choice of lighting affects not only the loss of working hours and fatigue of workers, but also increases the injury during the adaptation period when the worker does not see or difficulty seeing detail and performs work operations automatically. Similar conditions have been observed in assembly work in the evening under floodlights....
