The Twilight application makes the screen of your device adapt to the time of day. It filters the flow of blue light emitted by your phone or tablet after sunset and protects your eyes with a soft and pleasant red filter. The intensity of the filter is adjusted smoothly to the cycle of the sun according to the local hours of sunset and sunrise. The cause is the photoreceptor in your eyes, called Melanopsin. This receptor is sensitive to a narrow band of blue light in the 460-480 nm range that can suppress the production of melatonin, a hormone responsible for your healthy sleep-wake cycles.
