This screen fits the Apple iPhone 5, 5C and 5S SleepShield is the original high quality blue light blocking screen protectors. SleepShield blue blocking screen protectors work by reducing the Blue Light Rays you are exposed to from your phone. Studies show that people who use their phones before bed have a harder time falling asleep and staying asleep. The strong Blue Light rays from your phone instruct the brain to stay awake by suppressing melatonin production. When melatonin is released it is responsible for starting the natural sleep cycle, interfering with the production of melatonin can cause poor sleep. By reducing the amount of blue light, you can still enjoy your phone from the comfort of your bed and get a restful deeper sleep.
