About this app

Have trouble in sleeping after long time watching phone screen?

That is due to blue light. Blue light from your phone and tablet screen is the visible light spectrum for circadian regulation. According to the scientific studies, exposure to blue light imposes serious threats to retinal neurons and inhibits the secretion of melatonin, a hormone that influences circadian rhythms. It is proven that reducing blue light can greatly improve sleep.

❓ What is blue light?

It's part of a natural light spectrum, which disturbs the circadian rhythm and causes sleeplessness, headache and bad eye health. Unlike red light night shade, screen light blue light blocks the secretion of melatonin, sleep hormone, and causes restlessness. Retinal neurons are in danger if night filter anti glare is not used after twilight for eye care.

Features:

● Reduce blue light
● Adjustable color Filter
● Save power
● Very easy to use
● Built-in screen dimmer
● Eye protector from screen light
● Different Color Filter r
● Different Mode for Movie, Game, Reading
😕 The negative effects of blue light flux are:

• Eye strain, tired eyes and bad eye health
• Higher risk of glaucoma, and cataract
• Phase shifting of the circadian rhythm, restlessness, and suppression of melatonin
• Chronic migraine pain and activation of the trigeminal nerve
• Chronic headache
• Insomnia, sleepless night time and sleeplessness

High Sensitivity of the Human Circadian Melatonin Rhythm to Resetting by Short Wavelength Light
Steven W. Lockley, George C. Brainard, Charles A. Czeisler, 2003


📱 Premade blue light filters - Use one of 5 anti glare bluelight flux filters to activate night mode and warmlight (red light) for eye care against natural light blue rays. Relieve eye strain, macular degeneration, glaucoma and cataract with night filter during sleepless night reading.

💾 Saving and editing night mode filters - Create and edit a night shift filter to rest your tired eyes from screen light or make a set of night filters to protect eyes, fix circadian rhythm, sleeplessness, insomnia and lack of melatonin after twilight.

🌚 Dimming below system minimum - Use "Dim" night screen option to protect eyes from natural light blue rays. It's best for good eye health and chronic headache relief during night reading because it gives a night shade warmlight in form of a night light.

🌈 Color customization - Use "Color" palette to adjust the color tint, intensity and dim for your night screen. Night filter provides eye care and relief from migraine pain caused by screen light.


🔋 Reduce power usage - Bluelight flux night shift reduces the night screen power usage. Use natural light filters to reduce night light power usage while relieving chronic headache and repairing circadian rhythm curing your sleeplessness.
