We all know that we should take breaks during prolonged periods of monitor use, but what is really happening when we overexert our eyes? Staring at your monitor can lead to a variety of ailments, including headaches, eyestrain, blurred vision, dry and irritated eyes, slow refocusing, neck and/or backache, sensitivity to light, double vision, and color distortion. Install the EyeShield break reminder at your work station.
