Thanks to you for downloading and using our application: Twilight! French translation by Jeremy Del Grosso (Genetik57)
Recent research suggests that exposure to blue light before sleep can distort your (circadian) rhythm and cause this inability to fall asleep.
The cause is the photoreceptor in your eyes, called Melanopsin. This receiver is sensitive to a narrow band of blue light 460nm-480nm Between, this range can suppress the production of melatonin – a hormone responsible for your healthy sleep-wake cycles.
The twilight application adapts to the screen of your device at the time of day. It filters the blue spectrum on your smartphone or tablet after sunset and protect your eyes with a soft and pleasant red filter. The filter and intensity is adjusted smoothly to the solar cycle based on the sunset and sunrise from your local time.
