컴퓨터를 사용할 때, 눈이 피로하게 됩니다. 물론 이것은 장시간 가까운 거리에서 화면을 볼 때 발생됩니다. 그러나 TV와 같은 다른 디바이스와 비교하면 훨씬 더 큽니다. 그렇다면 어떻게 하면 줄일 수 있을까요? EIZO는 "눈이 좋아하는" 이상적인 모니터를 만들기 위하여 눈의 피로 원인을 찾아보았습니다.
LED backlight causes eye fatigue?
Since the popularization of LED backlights, the number of people who report eye fatigue caused by flicker has increased. Some people perceive the high speed at which the LED backlight flashes as flicker. Of course, even those who cannot perceive flicker may also be affected by it without realizing it.
How does flicker work?
Dimming (brightness control), is separated into 2 categories: PWM (pulse-width modulation) and DC (direct current).
LED monitors often use PWM. The design is simple and easy to mass produce.
Does flicker really cause eye fatigue?
We conducted an experiment to find out how users felt about viewing variable light.

Did you perceive flicker?
Did you feel eye fatigue?
Lastly, which was the easiest to view?
At EIZO…
We have developed a hybrid model that combines the pros of PWM and DC dimming.
밝은 화면이 눈의 피로를 주나요?
밝은 화면이 처음에는 선명하고 보기에도 좋다고 느낄 수 있습니다. 그러나, 너무 밝은 화면은 눈의 피로의 주 원인입니다. 반대로 디스플레이가 너무 어두우면, 보기도 힘들고 눈의 피로를 더 가중시킵니다. EIZO에서는 화면의 밝기를 주변 밝기에 따라 적절하게 자동 조정하는 Auto EcoView 기능을 제공하며 아래와 같이 테스트 하였습니다.

최적의 밝기 레벨에서 피로를 줄입니다.
EIZO는
일반 모니터에 Auto EcoView 기능의 자동 밝기 조정 센서를 탑재하였습니다. EIZO Auto EcoView 기능은 화면이 너무 밝거나 너무 어둡지 않도록 합니다; 최적의 밝기 레벨로 자동 조정하여, 장시간 컴퓨터 작업으로 발생되는 눈의 피로를 덜어줍니다.
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.
When comparing the relationship between LED and blue light, we have confirmed that LED backlights and CCFL backlights have about the same amount of blue light.
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.
