Abstract

It has been reported that visibility has been reduced as a result of changes in light sources used for inspecting and repairing railway stock from incandescent lamps to LED lights. Notably, workers in their 50s have reported that objects look flat under LED lights. This study examined the effects of the wavelength and illumination levels of lighting on fine depth discrimination ability. The results indicated that appropriate illumination levels and the wavelength of light that result in high visibility might not be different depending on the age.
