About this app

Did you know that long-term exposure to Blue Light is harmful to your eyes 👀?
Do you have trouble falling asleep or sleeping soundly after staring at your phone for a long time 🙄?
Do you become tired or have dry eyes after using your phone or tablet 😵?

That's true; the Blue Light on your phone screen has affected you. So, what is the reason?
The Blue Light on your smartphone and tablet screens will be in the visible light spectrum, with wavelengths ranging from 380 to 500 nm. It can occasionally become purple with a wavelength close to 450 nm.
According to WHO specialists' scientific research, long-term exposure to blue light has a detrimental effect on your eyes. In particular, your vision or body cells can face the following problems:
👀 You are more prone to developing diseases such as cataracts, macular degeneration, eye strain, eye refraction, and more.
😵 Blue light has a detrimental influence on your circadian rhythm by inhibiting hormones that affect human circadian rhythms. Because of biological sleep disruptions, you will have difficulty falling asleep and sleeping deeply.
👁️ Another incredibly negative impact is that blue light is one of the causes of accelerated skin aging, wrinkle development, and increased skin pigmentation.
You can adjust the screen light by color: Black, Orange, Green, Red ... or RGB color combination.
Adjust the light intensity to make your eyes as comfortable as possible
The Night Shift Blue Light Filter has been developed to reduce the blue light on your phone or tablet screen. Natural hues will be suggested so that your eyes can easily adjust to the modes:
⛺ Night Shift
🕯 Candle Light
🌄 Aurora
🌅 Sunset
🔦 Fluorescent light
💡 Incandescent light

You can easily adjust the light mode to suit your eyes with this app. Adjust the brightness and intensity of the light and reduce blue light to the greatest extent possible to protect your eyes, aid in sleep, and protect your facial skin.
Download and use the e Night Shift Blue Light Filter app to light the future with healthy eyes.
