With our active lifestyle, we regularly came across the digital screens. These digital devices emit blue light which is similar to the light emitted by the sun during noon.

This light controls the emission of Melatonin which is responsible for triggering sleep during evenings. Exposure to this kind of light during the evening, from screens, causes the imbalance in the production of Melatonin which ultimately affects our sleep. This light may also create digital eye stress.

By using blue light filter apps, there is a decrease in the amount of blue light produced by screens. You can also use night shift option on iPhones or iPads which is now available on iOS with version 9.3 or newer.

How To Use Night Shift on iPhone
