BenQ ScreenBar Halo vs Xiaomi Monitor Light Bar: An Optometrist's Comparison

A monitor light bar is one of those desk accessories you don’t realize you need until you try one. Instead of a desk lamp that creates glare on your screen and takes up valuable desk space, a light bar clips onto the top of your monitor and illuminates your keyboard and desk area without any screen reflection.

As an optometrist, I’m a strong advocate for proper desk lighting. Poor ambient lighting forces your pupils to constantly adjust between a bright screen and a dark desk, which accelerates eye fatigue and contributes to digital eye strain. A monitor light bar eliminates that contrast difference — and that alone makes it one of the highest-impact, lowest-cost ergonomic upgrades you can make.
