Monitor light bars use asymmetrical optics to light your desk without screen glare. We ranked five options from ultra-budget to premium — BenQ ScreenBar Plus leads, Quntis is the value pick, and the Halo is the stretch upgrade for maximum eye comfort.
Late-night screen work is hard on your eyes. Overhead lights create glare on your monitor, and the contrast between a bright screen and a dark room forces your eyes to constantly readjust. Monitor light bars solve this with asymmetrical optics — they illuminate your desk and keyboard without reflecting off the screen, reducing both glare and harsh contrast shifts.
This guide covers five options from ultra-budget to a premium stretch pick, all focused on eye comfort and nighttime productivity. (Disclosure: we earn affiliate commissions on purchases through our links, but that doesn't influence our rankings.)
Asymmetrical optics is the key differentiator. Instead of spraying light in all directions, these bars angle light forward onto your workspace, keeping it off the screen. This eliminates the reflections that cause eye strain during long sessions.1
Auto-dimming adjusts brightness based on ambient light, so you don't have to fiddle with settings as the room darkens. Adjustable color temperature matters too — warmer tones at night are easier on the eyes and less disruptive to sleep.
USB power is standard across most options, so you don't need a wall outlet — just plug into your monitor or computer.
BenQ ScreenBar Plus is the product every other light bar is measured against. Its asymmetrical optical design eliminates screen glare by directing light only onto your desk, not your monitor.1 A wireless desktop controller lets you adjust brightness and color temperature without reaching up to the bar, and the auto-dimming sensor reads ambient light to keep things comfortable as your room darkens.1
It sits at the top of the price range for this guide, but if you want the most refined optical performance and the most convenient controls, this is the one.
Quntis matches the core features that matter — asymmetrical glare-free design, auto-dimming, and a wireless remote for brightness and color temperature control — at roughly half the price of the BenQ.3 It also supports curved monitors, which is a nice touch if your setup isn't flat.
If you want the essential eye-strain-reduction features without paying premium prices, this is the pick.
Xiaomi's Mi Light Bar brings premium build quality at a mid-range price. It uses a 2.4GHz wireless rotating remote for precise control, and a magnetic base lets you adjust the angle to fine-tune where the light falls and avoid reflections.4 The asymmetrical design keeps light off your screen.4
This is the pick if you want better build quality and more precise adjustability than the budget options offer, without stepping up to BenQ pricing.
HIOUME is the ultra-budget option designed specifically for smaller monitors. It's compact, offers 10 brightness levels and 3 color temperatures, and installs without tools.5 It won't match the optical refinement of the BenQ or the build quality of the Xiaomi, but for a tight budget and a smaller screen, it gets the job done.
The ScreenBar Halo is the premium upgrade. It adds an integrated backlight that illuminates the wall behind your monitor, reducing the contrast between your screen and the surrounding room — the single biggest cause of eye fatigue during long nighttime sessions.2 It also includes a wireless controller and is compatible with webcam mounts.2
This is above the $100 budget for this guide, but if you're serious about late-night eye comfort, the rear backlight is the feature that makes the biggest real-world difference.
| Glare control | Controls | Price tier | |

BenQ leads on optical quality and auto-dimming. Quntis matches the core features at half the price. Xiaomi offers premium feel at a mid-range price. HIOUME is the compact budget choice. The Halo is the premium upgrade for maximum eye comfort.
If you want the best overall, get the BenQ ScreenBar Plus. If you want the best value, get the Quntis. If you want maximum eye comfort and don't mind spending above $100, the BenQ ScreenBar Halo with its rear backlight is the ultimate upgrade.
