We spend an average of 8 hours looking at our mobile phones, tablets, and computers daily. But did you know that the blue light emitted by those screens penetrates all the way to the retina? Over time, that damages our vision, causes eye strain, and even contributes to sleep deprivation.
Harvard Medical School finds that even a little exposure to blue light wavelengths suppresses your body’s ability to make melatonin, a hormone that regulates sleep.
