Screen Lights is created for those people who spend a lot of time at night working. In addition to the LED screens in your electronics, energy-efficient lighting emits a lot of blue light. Exposure to blue light before you go to bed significantly affects your sleep quality, because it prevents your body from releasing melatonin, a chemical in your body that helps you sleep. Screen Lights reduce how much blue light your computer monitor emits, and it will change the color of your screen, which will reduce the amount of blue light your screen emits, helping you sleep better, reduce eye strain and helps you focus on the most important things on the screen.
