Dark mode doesn't directly reduce eye strain, but it can offer some relief. For example, in a dim setting, a bright screen has your eyes working harder. On the contrary, a dark screen in a brightly lit room will have the same effect. -Easier to read.
Dark mode reduces screen glare and blue light on laptop screens and mobile devices. However, there's no scientific evidence that the dark mode setting makes a real difference.
Summary: In people with normal vision (or corrected-to-normal vision), visual performance tends to be better with light mode, whereas some people with cataract and related disorders may perform better with dark mode. On the flip side, long-term reading in light mode may be associated with myopia.
Shifting to a dimmer screen may stop your eyes from transmitting wide-awake signals to your brain, and indicate that it's time for the body to rest. "It is true that dark mode has less light in general, so you could postulate that it would be a little bit better at preventing sleep problems," Dr. Bert says.
It could strain eyesight in brighter conditions
There's no evidence that dark mode reduces eye strain in brightly-lit conditions. In fact, it could strain eyesight because it causes your pupils to dilate. According to rxoptical.com, dark mode makes the eyes work harder since they need to absorb more light.
Also, Dark mode emits less blue light, which reduces eye fatigue and blinking (dry eyes), especially in low light conditions. Dark mode contributes to a better sleep if you worked before going to bed, which can be translated in a better work efficiency on the next day.
New research is detailing how blue light, which emits from smartphone and laptop screens, can damage your retinal cells, and possibly lead to macular degeneration, an eye disease that causes vision loss.
The idea behind Dark Mode is that it reduces the light emitted by device screens while maintaining the minimum colour contrast ratios required for readability. Thus reducing the strain experienced by human eyes while extending our smartphone battery.
Many people with migraine cite bright light as a migraine trigger, and retreating to a dark or dimly lit room provides relief for some during an attack.
When it comes to color combinations, your eyes prefer black text on a white or slightly yellow background. Other dark-on-light combinations work fine for most people. Avoid low contrast text/background color schemes. If you wear contacts, your eyes have to work harder when staring at a screen.
With a dark display (black background), the iris opens to receive more light and the deformation of the lens creates a much fuzzier focus at the eye.” In other words, people with astigmatism see dark mode interfaces with a slight blur which means their user experience is the exact opposite of accessible.
What percentage of people prefer to use dark mode on their devices? According to a 2020 survey by UX Design, approximately 88.6% of people prefer using dark mode on their devices.
While dark themes may be better suited for the night, they aren't necessarily helping you read better or saving your eyes from digital strain, or even saving a lot of juice on your device. You may also want to avoid dark mode altogether if you start noticing eyesight issues or increased sensitivity to light.
The Trend. Big companies have already been using Dark Mode for years on mobile devices (Twitter and YouTube, anyone?). As such, it's difficult to pinpoint exactly when the trend started, but as Apple, Microsoft, and Google hopped on the design trend around 2019, other companies slowly followed suit.
Diet, smoking and excessive alcohol can all make a difference to your eyesight in the long run. Long-term effects of consuming too much alcohol can increase your risk of eye disease, including AMD and cataracts.
Use proper lighting to reduce glare, so don't play in the dark or in extreme sunlight. Don't play video games for too many hours daily (more than three can be excessive). If you need to use a computer for your job, take breaks as frequently as you can and avoid additional screen time.
EyeComfort Mode is a viewing option under the Adaptive Picture feature that provides a picture setting comfortable to viewers' eyes based on sunrise/sunset times and surrounding ambient light. The sunrise/sunset time sync function in EyeComfort Mode may work differently, depending on the area and network connection.
Night Mode is a dark theme option available only on the Brave Browser for Android. Dark Mode, on the other hand, is available on the Brave Browser for Android as well as the Brave Browser for Desktop. Although Night Mode is an opt-in experimental feature, it does not require you to enable a flag.
The most fruitful battery life gains were found when switching from light mode at full brightness to dark mode. In the Purdue study (via Android Authority), researchers looked at dark mode power usage from six different applications.
It was thus found that the dark mode can significantly save battery life in peak brightness, usually employed by smartphone users in outdoor conditions under sunlight.
So far, the science doesn't support claims that dark mode improves sleep. Apple iPad users who used Night Shift (the brand's name for dark mode) didn't experience a difference in melatonin production compared to those who didn't use Night Shift, found a May 2019 study in Lighting Research & Technology.
It gave a surprising battery life figure. Changing from light to dark mode reduces the phone's power consumption by 42% at 100% screen brightness. When the brightness level is 50%, switching from light mode to dark mode saves 9 % of the battery, and when the brightness level is 30%, the saving is only 3 %.
Dark mode is better for people who have visual impairments. One visual impairment that benefits from dark mode screens includes people with cataracts. People with light sensitivities also seem to like it better.
