Twilight: Anti lumière bleue

Thank you to you for downloading and using our app: Twilight ! Translation French by Jeremy Del Grosso (Genetik57) Do you have trouble falling asleep ? Are you a hyperactive child who plays on their smartphone or tablet before going to bed? Do you use your smartphone or tablet late evening? Twilight may be a solution for you! Recent research suggests that exposure to blue light before sleep can distort your natural (circadian) This rhythm and cause an 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 between 460nm-480nm, this range can suppress the production of melatonin - a hormone responsible for your healthy sleep-wake cycles. In scientific experimental studies, it was shown for the average person that reading on a smartphone or tablet two hours before sleep can make it shorter by about an hour. The application Twilight fit the screen of your device at the time of the day. It filters the blue spectrum on your smartphone or tablet after sunset and protect your eyes with a mild and pleasant red filter . The filter and the intensity is adjusted smoothly to the solar cycle based on sunset and sunrise from your local time . Service d'accessibilité Afin de filtrer également vos notifications et votre écran de verrouillage, l'application peut vous demander d'activer le service d'accessibilité Twilight. L'application utilise ce service uniquement pour mieux filtrer votre écran et ne collecte aucune information personnelle.

Vous pouvez contrôler le filtrage à partir d'une "tuile Wear OS Tile".
