Abstract：The effects of the retinal illuminance, circadian rhythm and blue light hazard of the different LED backlight displays on the eyes of different ages are studied.The normalized white and blue spectral distributions of four common displays are measured, the retinal illuminance factor, blue light hazard factor and circadian factor of different displays are calculated, and then the relationships among these factors of different displays are obtained.It shows that the above three factors decrease as the age increases for all the displays, regardless of blue or white background.The illuminance factors show similar values with various ages for the same display.For the same young eye, the illuminance factor of different display changes little. However, the blue light hazard factor and the circadian factor are different.
