Twilight

What is Twilight?

The Twilight app is designed to optimize your device's screen for optimal eye health and sleep cycle alignment. By filtering the blue spectrum of light on your phone or tablet after sunset, the app helps protect your eyes from the potentially disruptive effects of blue light exposure. The filter intensity is seamlessly adjusted based on your local sunset and sunrise times, ensuring a smooth transition that follows the natural sun cycle. This feature can be particularly beneficial for individuals who struggle with sleep issues or have difficulty winding down before bedtime, as research has shown that blue light from digital screens can delay the onset of sleep. With Twilight, you can enjoy your device use in the evening hours without compromising your natural sleep-wake rhythms
