Last but not the least, BenQ’s low blue light setting is a must. As blue light is everywhere, BenQ Low Blue Light Technology blocks high energy blue light (420-480nm) emitted by your monitor, which could harm your eyes when reaching your retina. You will feel comfortable even after using the monitor for a long time. Based on Low Blue Light Technology, a customized reading mode was developed: ePaper Mode. It’s especially designed to make reading a much more comfortable experience, as if you were reading real paper. By using low blue light, low contrast, black letters, and a white background, ePaper Mode offers comfortable reading right on your monitor.
