Twilight 12.11

Do you have trouble falling asleep? Are your children too active when playing on a tablet or phone before going to bed?
Do you use your smartphone or tablet late at night? Twilight may be the solution for you! Recent studies prove that the perception of blue light before going to bed can upset your natural (circadian) rhythms and cause inability to fall asleep.

The reason is in the photoreceptors of the eyes, called Melanopsin. This receptor is sensitive to a narrow band of blue in the range of 460-480 nm, which affects the production of Melatonin, the hormone responsible for your healthy sleep-wake cycles. In experimental scientific studies, an average person was shown reading from a smartphone or tablet for several hours before going to bed, which caused a delay in sleep for about an hour.

Twilight makes the screen adapt to the time of day. It filters out the blue spectrum on your phone or tablet after sunset and protects your eyes with a soft and pleasant red filter. The intensity of the filter is smoothly adjusted relative to the solar cycle and is based on the time of your local sunset and sunrise. The latest version of the app Twilight download for android.
