Give your eyes the break they deserve with applications that help your devices adjust the color of the light output to levels that are more comfortable and less damaging to your eyes.

Kelvin is a unit of measurement used to describe the hue of a specific light source. This is not necessarily related to the heat output of the light source but rather the color of the light output. The higher the Kelvin value of the light source, the closer the light’s color output will be to actual sunlight.

1f.lux – Software to make your life better

f.lux leverages the location (coordinates) information of your devices to adjust the hue/colors to better suit the time of day. At night, the colors adjust automatically to a level closer to halogen instead of the intense light of daytime that can toast your eyes at nighttime.

The app is supported on MacsWindowsLinux, jailbroken iPhones/iPads and rooted Android devices.

2Twilight

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.

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.

Here’s more information on how to enable nightshift on your iOS device.

Bright blue-white light blasting in your face at night isn’t so great for your sleep or general health, but don’t worry: iOS now supports color shifting so you can warm up the light of your iPhone for easy nighttime reading.

There is a growing body of research that exposure to artificial light late into the evening, especially blue light like the crisp blue-white glow of our beloved gadgets, is a serious issue that effects our sleep cycles and general health.
