Twilight: Blue light filter v13.8

Are you having trouble falling asleep Your kids are hyperactive when they play with the tablet before bed. Do you use your smartphone or tablet late in the evening? Twilight may be the solution for you! Recent studies show that exposure to blue light before bed can distort your natural (circadian) rhythm and cause you to be unable to fall asleep. The cause is a photoreceptor in your eyes 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, the hormone responsible for your healthy sleep-wake cycles. a smartphone a couple of hours before bedtime may find that their sleep is delayed by about an hour.

If users don’t like the automatic brightness correction feature, the app will introduce many unique and useful light filters for the device. These filters are sometimes referred to as Sun, Alarm, Custom, and Always. The effects and possibilities of each option are different and varied, along with extensive customization for users to change their quality. In addition, the constant change of filters is also useful, helping the eyes to adapt to a variety of pleasant and healthy light. Blue light is the light that is most often harmful in dark places or at night when the user’s eyes are tired and more sensitive. Such light is extremely harmful when used for a long time, but “Twilight” can reduce its dangerous intensity, even protect the eyes and give the user a good sleep.

So what is the reason for the above difficulties in this application and how is the explanation given? Recent scientific studies have shown that we often use mobile devices, tablets before going to bed every night. Since then, a frequent occurrence has shown us that blue light coming from a phone screen will lead to circadian rhythm problems in humans. Therefore, it is very difficult for people to fall asleep at night after using the phone. But how clearly will modern science explain this? The main reason has to do with the melanopsin receptor in the human eye, which has been found to be very sensitive to blue light. A particularly narrow blue light in the 460-480nm range comes from the phone’s screen. This will prevent the production of melatonin, a hormone that affects human sleep.
