Health-Guard

Health-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.
