“Unfortunately, externally driven distractions don’t just disappear by changing their colour, and internally driven distractions aren’t inhibited by looking at something dark,” says Cox. This is explained by the nature of distraction, which come from two sources: one is external – your phone buzzing or someone shouting your name – and the other is internal: your brain spontaneously popping on an embarrassing memory clip from five years ago. Cox too, disputes the claim that dark mode would assist concentration, saying she is not aware of “any mechanism” that would mean this is the case. “If anything, lighter backgrounds have been proven to be better for concentration and performance,” says Singh. Dark mode increases concentration and decreases distractionĭark mode has been associated with claims about our ability to focus: Apple launched Mojave’s dark mode with the promise of a “distraction-free working environment that’s easy on the eyes - in every way.” But is there any reason to believe that dark mode delivers a boon for concentration?

A report from iFixIt found there was a 63 per cent drop in power usage for an Android phone displaying a screenshot of Google Maps in night mode. For these phones, dark mode can offer healthy battery saving capabilities. Other phones with OLED displays include the Samsung Galaxy S10 and the Huawei Mate P30. The iPhone X was the first Apple phone to launch with an OLED screen.
Until recently, most phones were made with LCD screens. On these tasks, participants both read faster and/or spotted more mistakes in the positive polarity condition. The study involved participants carrying out both visual acuity tests and proof reading tasks.
Research published in 2013 by psychologists Cosima Piepenbrock and Susanne Mayr showed that accuracy and performance are better in positive polarity conditions (i.e. If the contrast is the same between normal and dark modes, she says we might not expect a difference in legibility, although our familiarity with black text on a white background might offer this display mode a slight edge. In terms of readability, ensuring a higher contrast between text and background is more important than colour scheme, according to Cox. You can also make use of the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds. Limiting screen time is the top tip from the Mayo Clinic. Adjust your screen at or below eye level – having your screen above eye level can dry your eyes out further.īut the best solution might be to drag yourself away from your computer altogether. You might want to check light sources around you too – glare from overhead lighting reflected on your screen can make it harsher.
For the device itself, recommendations include raising the contrast of your screen, or adjusting the brightness so it’s no lighter or darker than your surroundings. If truly concerned about eye strain or dryness, you might be better off investing in artificial tears or a matte screen for your device. Conversely, in a brightly lit environment, a darker screen can actually force your eyes to work harder. “In a darkened room, the darker colours of dark mode could be perceived as less jarring and lull people into spending longer using the app,” says Aneesha Singh, professor of human-computer interaction at UCL. In a dimly lit environment, where the main light source is your screen, the greater the eye strain provoked by a brightly lit display. However, the effort of looking at a screen can vary a lot depending on your surroundings. One of the oft-repeated claims about dark mode is that it’s exactly that, but is this based on fact? Anna Cox, a professor of human-computer interaction at UCL, dispute this is the case, saying, “I’m not aware of any robust evidence that white text on black background reduces eye strain”. No wonder then, that anything offering a solution to this condition is touted as a miracle cure.
