Blue light causes eye fatigue?
How blue light influences eye fatigue is an increasingly popular topic. First we will show where blue light falls on the light spectrum.
Blue light is part of the visible spectrum and has a wavelength that is close to that of ultraviolet light.
99% of the ultraviolet rays that reach the Earth are UVA with a wavelength of 315 - 400nm. Although blue light is part of the visible spectrum, it still has an influence on eye fatigue. Since its wavelength puts it close to UVA, it is conceivable that it could cause strain on our eyes.
How to reduce blue light on an LCD monitor
Knowing that blue light influences eye fatigue, we tested how much we could decrease the amount of blue light by making adjustments to the monitor.
Lowering the color temperature
Lowering the color temperature causes light distribution to shift towards longer wavelengths (more reddish colors). When we change the initial color temperature of our monitors (6500 - 7000K) to 5000K...
Lower Color Temperature and Brightness
By lowering the brightness you can reduce overall energy usage. When we adjust the monitor's brightness down from the highest setting to an adequate value (approx. 20 cd/m², and the color temperature to 5000K...
At EIZO
We greatly adjusted the monitor's brightness and color temperature resulting in a reduction of the effects of blue light using various technologies. We were able to create a comfortable viewing environment with Auto EcoView automatic brightness adjustment and Paper mode, part of Fine Contrast presets.
