Tests have shown that at a brightness level of 30%-50%, the energy saved in Dark Mode is 3%-9%, but the values increase exponentially the closer you get to 100% brightness. Therefore, by reducing energy consumption we could help minimize damage to the environment: a simple click for you, a big result for the planet.
Less power when displaying also means you extend your battery life. Due to the power-saving of dark mode, you save electricity needed to power your devices and their activities and also generate less carbon footprint. So, even in small amounts, you become more ecological and planet-friendly.
Reduces eye strain at night and cuts glare
Dark mode users find reading easier in low light with less eye strain. They also claim it helps them fall asleep quickly and stay asleep longer. This could be because screens expose you to more blue light at night, which could disrupt your circadian rhythm.
Studies have shown that people with normal or corrected vision have a better performance, however, people with stronger visual disorders will tolerate Dark mode better. But Light mode has a cost associated to the better performance, and it is the long-term risk of eye disease.
Cons of Dark Mode
Dark mode may increase eye strain in brightly-lit conditions. Dark mode can cause halation for individuals with myopia or astigmatism, making text less readable for them. Dark mode may lower reading comprehension and focus. Dark mode does not improve battery life on older devices without OLED screens.
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.
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.
Is dark mode better for your eyes? While dark mode has a lot of benefits, it may not be better for your eyes. Using dark mode is helpful in that it's easier on the eyes than a stark, bright white screen. However, using a dark screen requires your pupils to dilate which can make it harder to focus on the screen.
TLDR — dark mode makes astigmatism worse. So your dark mode could be messing with the user experience of up to 47% of your user base.
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.
Dark modes or dark screen backgrounds decrease the amount of blue light you receive from your device and computer screens so that your eyes aren't as strained and so you can more easily turn off the workday to get to sleep faster.
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. How does dark mode usage affect battery life on devices such as smartphones?
Certain coding languages may become more legible in dark mode, depending on the style and font. In addition, the light-on-black color scheme of dark mode can assist with syntax highlighting by allowing programmers to more easily distinguish different-colored fonts.
A smartphone can save about 39 to 47 per cent of battery power at peak brightness by operating on dark mode.
According to Timo Partonen, Research Professor at the National Institute for Health and Welfare, the quality of sleep is simply better in the dark than in the light. “Melatonin is the main sleep-producing hormone in humans. The body produces it in large quantities only at night and in the dark.
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.
Particularly, when using the display for work, you'll often be comparing paper documents with documents on the screen, so by adjusting the brightness of the screen to the brightness of the paper under the lighting, you'll reduce the strain on your eyes, making this an effective measure against eye fatigue.
There are other benefits to grayscale mode as well: It can be easier on your eyes and help you read and view things better if you're colorblind. Turning your iPhone black and white is easy—and switching back and forth is easy, too.
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.
While dark mode does lessen the screen's overall brightness, which may seem easier on your eyes, it also causes your eyes to dilate. Since there is less light to take in, your eyes have to work harder to see clearly. Eye dilation can reduce your vision's sharpness, so you may have to strain to see well.
Using Night Mode on Your Device
With reduced white colors and minimal contrast, the Night Shift can, in turn, reduce the blue light emission. Most phones' night mode will automatically adjust when the battery is low or it detects a low-light environment.
#4 Ensure that your content is Dark Mode friendly
That means that a bright white phone screen may have us at a disadvantage before we even see your content. A lot of folks with ADHD love dark mode (cue me squinting like Gollum at every white background that pops up on my computer) as a way to reduce visual input.
It Might Be Affecting Your Mood
Here's what I do know: The deprivation of light can change how our brains work and can lead to greater levels of depression.
Turns out that it's less about what the darkness shuts out than about what it enables. For one thing, darkness makes it easier to think analytically because it makes our emotions less distracting.
