Many individuals spend long hours on Windows 11 PCs, which can lead to eye strain and discomfort. To alleviate these issues, users can adjust screen brightness using the Quick Actions panel, customize the size and color of the mouse cursor in the Accessibility settings, and modify text and icon scaling in the Display settings. Enabling dark mode can reduce eye strain, while the Night light feature helps minimize blue light exposure. Color filters are available for colorblind users, and contrast themes can enhance visual clarity for those needing more distinction between UI elements. Implementing these adjustments can improve comfort and productivity.
