Lowering Blue Light
Blue light with wavelengths between 415 nm and 455 nm is
considered harmful for the eyes. It may cause eye
discomfort, suppress melatonin, and affect sleep quality and
circadian rhythm. This product has the function of reducing
blue radiant energy.
To avoid eye fatigue, it is recommended to place the product
at an appropriate distance from your eyes and rest for 20
minutes to look into the distance after two hours of
continuous viewing.
To enable eye protection, open the Settings app and touch
Display > Night Light > Turn on now. Use Turn on
automatically to enable eye protection between sunset and
sunrise or during customized time. In addition, you can
adjust the protection effect by changing the blue light filter
and white point reduction levels.
