ASUS Eye Care Monitors receive the most number of TÜV Rheinland Low Blue-Light Emissions and Flicker-Free Certifications. Four different Blue Light Filter settings are accessible onscreen through the OSD menu on ASUS Low Blue Light Monitors. Also, ASUS Flicker-Free technology uses Smart Dynamic Backlight Adjustment to reduce flicker; this protects users from eye fatigue, irritation and strains. This technology helps minimize instances of eyestrain and other damaging ailments, especially when spending long hours in front of a display.
