6 Best Eye Filter App For Android
1. Twilight: Blue light filter
“Are you having trouble falling asleep? Are your kids hyperactive when playing with the tablet before bed time?
Are you using your smart phone or tablet in the late evening? Twilight may be a solution for you!
Recent research suggests that exposure to blue light before sleep may distort your natural (circadian) rhythm and cause inability to fall asleep.
The cause is the photoreceptor in your eyes, called Melanopsin. This receptor is sensitive to a narrow band of blue light in the 460-480nm range which may suppress Melatonin production – a hormone responsible for your healthy sleep-wake cycles.
In experimental scientific studies it has been shown an average person reading on a tablet or smart phone for a couple of hours before bed time may find their sleep delayed by about an hour. See references below..
The Twilight app makes your device screen adapt to the time of the day. It filters the flux of blue light emitted by your phone or tablet after sunset and protects your eyes with a soft and pleasant red filter. The filter intensity is smoothly adjusted to the sun cycle based on your local sunset and sunrise times.
Get more from Twilight
1) Bed reading: Twilight is more pleasant on the eyes for night reading. Especially as it is able to lower the screen backlight far below the ability of the backligt controls on your screen
2) AMOLED screens: We have tested Twilight on an AMOLED screen for 5 years without any sign of depletion or over-burning. If properly configured Twilight causes less light emission (by enabling dimming) with more equal light distribution (dark areas of the screen such as the status bar get tinted). This may in fact increase your AMOLED screen life time.
Basics on circadian rhythm and the role of melatonin
– location – to find out your current sunset/surise times
– running apps – to stop Twilight in selected apps
– write settings – to set back-light
– network – access smartlight (Philips HUE) to shield you household light from blue

2. Night Owl – Screen Dimmer & Night Mode
Night Owl filters out blue light and reduces the brightness of your phone’s screen more than you can achieve with Android settings, which helps you avoid eye strain, insomnia (inability to sleep), and headaches when staring at your phone in the dark.
• Dim the entire screen, notification icons, and notification drawer
• Easily adjust the filter intensity in the app or from the notification.
• Filter the blue light or customize the tint color.
• Schedule the app to start and stop automatically via timer or sun scheduler.
• Shake the device to stop the app. (optional)
• Disable auto-brightness and lower device brightness to minimum automatically when the app starts. (optional)
• Use quick setting tiles to start or stop the app quickly.
Night Owl uses the “Display over other apps” feature to put a filter on the screen to make it darker than usual and/or change its color.
Beta feature: Night Owl uses Android’s accessibility feature to display a tinted overlay over the screen (including notification and lock screen) to make it darker than usual and/or change its color. Night owl does not read your screen content and does not collect any data through the Accessibility service. You need to enable Night Owl Accessibility to use the app.”
3. Blue Light Filter – Night Mode
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 (380-550nm) 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.
Blue light filter is used to reduce blue light by adjusting the screen to natural color. Shifting your screen to night mode can relieve your eyes strain, and your eyes will feel at ease during night reading. Also blue light filter will protect your eyes and help you sleep easily.
