Do your eyes feel tired while reading at night on the phone?
Having trouble sleeping after looking at your phone screen for a long time?
This is due to the blue light. The blue light of the phone and tablet screen is the visible light spectrum (380-550 nm) for circadian regulation. According to scientific studies, exposure to blue light poses serious threats to retinal neurons and inhibits the secretion of melatonin, a hormone that affects circadian rhythms. Reducing blue light has been shown to significantly improve sleep.
The blue light filter is used to reduce blue light by adjusting the screen to a natural color. Moving the screen to night mode can relieve eye fatigue and your eyes will feel comfortable when reading at night. In addition, the blue light filter will protect your eyes and help you sleep easily.
