Twilight Blue light filter for better sleep Pro V 12.9 APK

Descriptions :

Recent research suggests that exposure to blue light before bed can distort the natural (circadian) rhythm and cause the inability to fall asleep. The cause is the photoreceptor in your eye, called melanopsin. This receptor is sensitive to a narrow band of blue light in the 460-480nm range which can suppress the production of melatonin, a hormone responsible for your healthy sleep-wake cycles. In experimental scientific studies it has been shown that the average person reads on a tablet or smart phone for a couple of hours before going to sleep, sleep may be delayed by about an hour.
