摘要：

The aim of this study was to examine the impact of the blue light from the visual display terminal (VDT) on visual search tasks. We assessed the quantity of the blue light from medical imaging diagnoses (medical-grade) liquid-crystal display (LCD) and general (personal computer-grade) LCD for the VDT work, both equipped with the blue light reduction function. Then, we measured the visibility of display by evaluating the correct answer rate and reaction time of visual search tasks. The quantity of the blue light was proportional to the luminance of the display. When the blue light reduction function was used during the VDT work, the blue light at the peak wavelength was reduced by about 56%. Though the luminance of the display reduced, the visibility of the display was not decreased. These findings suggest that the blue light reduction on the LCD could work efficiently in the VDT work, maintaining the visibility of the display.
