Abstract

Nowadays, display panels use white LEDs backlight to provide thin and lightweight devices with high brightness. The spectrum of white LEDs has an important blue component with a peak wavelength around 450 to 470 nm. The term “blue light hazard” (BLH) refers to the photochemical damage of the retina in the range of 380–550 nm. Blue light retinal injury can result from viewing either an extremely bright light for a short duration or a less bright light for a longer duration. Our studies and measurements focused on usual display panels of desktop and laptop PCs, used many hours a day by the operators who are endangered by the cumulative effect of blue light exposure. The paper will present the results and recommendations in order to order to minimize the risk of blue light exposure.
