Sleep Tight with Less Blue Light

Body clock mechanism and ideal lighting condition

Research indicates that exposure to blue light emitted by electronic devices after sundown impacts sleep. However, blue light can be beneficial during the daytime. Sun is our major source of light and incudes blue light wavelengths to wake us up and boost our attention. This body clock mechanism is called the “Circadian Rhythm” or sometimes the “Circadian biological clock”.
As a visual technology company, EIZO has been incorporating visual ergonomic features into our monitors for years. Since 2010, many of our monitors have been equipped with a blue light reduction feature called “Paper Mode.”

In 2014, we introduced a “Circadian Dimming” feature. This feature controls the change in color temperature of the monitor throughout the day. As the evening approaches, the color temperature is lowered, decreasing the blue light emission from the monitor. The Circadian dimming feature is available with the EIZO FlexScan EV series of LCD monitors listed below.
