Bluelight Filter - Anti-Glare and Night Mode

想在黑暗中使用智能手机时减轻眼睛疲劳吗？

Have trouble falling asleep?

Want to reduce eye strain when using smartphones in the dark?

Blue Light app may be the solution for you!

With "BlueLight" you can block the blue light and adjust brightness of the screen in dark places so that you can keep your eyes healthy and have a good night’s sleep.

Blue light is a range of the high-energy visible light spectrum, defined as having a wavelength between 400-495 nm, has a negative impact on sleep as it disturbs the production of melatonin, an essential sleep hormone. Other harmful effects of using the smartphone without blue light filter are: eye strain, headache, insomnia or sleeplessness, lack of quality sleep, etc.

Night mode adjusts the colors of your display to the warmer end of the spectrum—making the display easier on your eyes. Also here are even more options - selecting the filter color according to color temperature, shortcuts on the home screen, a notification widget and an activation time schedule.

You will find "Blue Light" useful when

- to block the harmful blue light emitted by device screens

- the built-in blue light filter in OS is not enough.
