Worried about eyestrain from blue light? Eyesafe has an in-display solution for the latest Dell laptops
The technology adjusts the wavelength of blue light at the source and then performs the necessary color correction to reach the original gamut of the panel. The end result is a display that automatically reduces "harmful" blue light without impacting colors or requiring special filters or glasses from the end user.

Blue light from digital displays like smartphones, tablets, and laptops are believed to be responsible for causing eyestrain and disrupting sleep patterns. Some laptops, tablets, and monitors offer "Reader Mode" or "Blue Light Filter Mode" which automatically adjusts the colors of the screen to reduce "harmful" blue light. Examples include the Huawei MediaPad tablet and the LG Gram series. There are even special glasses available to reduce incoming blue light. The intent is to make the display easier on the eyes for long periods of reading or gaming at the cost of color accuracy.

Through a new partnership with Dell, Eyesafe will be introducing a new approach to blue light filtering. Instead of requiring special glasses or filters that will indubitably impact colors, Eyesafe will calibrate the displays before shipment via both hardware and software to reduce blue light without distorting the original colors of the panel. Eyesafe says it is able to achieve this by shifting the wavelength of blue light from the standard 440 nm to the less harmful 460 nm and then tuning the colors as needed.

The technology will appear first on the Dell Alienware Area-51m, Dell XPS 13 2-in-1, and the Alienware m15 with many more laptops to come. This feature is particularly lucrative for Dell because of its partnership with Team Liquid and various eSports events where the blue light filter would benefit pro gamers.

Eyesafe says we can expect this same technology to appear on other devices from different OEMs at CES 2020.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
