wilight might be a solution for you! Recent research suggests that exposure to blue light before bed may distort your natural (circadian) rhythm and cause you to be unable to sleep. The cause is the photoreceptors in your eyes, called melanopsin. This receptor is sensitive to a narrow band of blue light in the 460-480 nanometer range that may inhibit the production of melatonin – a hormone responsible for healthy sleep-wake cycles.
In experimental scientific studies, it has been shown that the average person who reads on a tablet or smartphone for a few hours before bedtime may find that their sleep is delayed by about an hour. See references below..
