Eye strain at the screen: light bar or desk lamp?
Eye strain at the screen comes from the contrast with a dark room, not from blue light. YEELIGHT and Xiaomi monitor light bars, Philips Hue Play.
Our pick: YEELIGHT monitor light barSee on Amazon
Our pick
YEELIGHT monitor light bar
A bar resting on the screen lights the desk without throwing a single reflection onto the panel. That is what a normal desk lamp cannot do.

Other situations
For a fixed desk, the YEELIGHT is the best balance of controls and no glare. If you draw, edit photos or work on paper, the Xiaomi bar renders colours more faithfully, Ra95 according to the brand. In the evening, a Philips Hue Play placed behind the screen lights the wall and narrows the brightness gap further.

How these were chosen
- No reflection on the panel
- That is the whole point of a bar. If the light shows in the screen, it makes the contrast worse instead of better.
- Adjustable colour temperature
- Warm in the evening, neutral during the day. A fixed-temperature bar forces you into a permanent compromise.
- Length relative to the screen
- A bar wider than the screen overhangs and tires the periphery. Shorter, and it leaves the edges of the keyboard in shadow.
The real culprit is contrast
A screen at full brightness in an unlit room forces the pupil to keep adapting between two very distant levels. That gymnastics is what tires you, not the colour of the light.
The fix fits in one sentence: light the room and the desk without lighting the screen.
Why a normal lamp is not enough
Placed beside the screen, it always ends up reflecting in the panel, especially on glossy finishes. Placed behind, it lights the wall and dazzles over the top of the screen.
The bar solves the problem geometrically: it sits above, aimed at the desk, and its housing blocks the beam that would come back to the panel.
The order of fixes
Screen height first, then room lighting, then the bar. Reversing that order means treating the cheapest symptom first.
If you only do one thing tonight: drop your screen brightness by two steps and turn on a light behind you, not in front.

Derrière l’écran
Philips Hue Play Light BarWhite and colour light bar (black)
Placed behind the screen, it lights the wall: the brightness gap between the panel and the room shrinks, and that gap is what tires your eyes in the evening. White from 2,000 to 6,500 K plus colours, 500 lumens at 4,000 K according to Philips.
- Positionbehind the screen, upright, flat or mounted on the back with the included brackets; 25.3 cm long
- Powermains power supply, up to three bars per supply; 6.6 W
- Controlswhite from 2,000 to 6,500 K plus colours, Hue app, Alexa, Google Home, Apple Home; Hue Bridge required according to Philips
Avoid ifYou have no Philips Hue Bridge: Philips lists it as required, and it is sold separately. It does not light the keyboard: it complements a bar or a lamp, it does not replace one.

Frequently asked questions
Is blue light really to blame?
Screens emit far less of it than daylight. What tires you is a bright screen in a dark room, a screen set too low that holds the eyelids open, and forgetting to blink.
Should I switch the ceiling light off?
No. The aim is to reduce the gap between screen brightness and room brightness. A soft ceiling light plus a bar beats either one alone.
Does a bar replace a desk lamp?
For reading on screen, yes. For writing by hand or reading paper, an adjustable lamp stays more comfortable.
