Aside from the possibility that a black screen might trigger negative emotions, there are a number of other reasons why people might not want to use dark mode. In some cases, Goldberg explained, dark mode "can actually make it more challenging for our eyes to resolve smaller fonts."
Dark colors can evoke negative emotions connected with sadness, mourning, or depression. 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.
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.
Cons: Dark themes are not always better for eye strain. In bright light conditions, the text appears washed out, increasing eye fatigue. Long pieces of content or text are more challenging to read in this mode.
Conversely, in a brightly lit environment, a darker screen can actually force your eyes to work harder. If truly concerned about eye strain or dryness, you might be better off investing in artificial tears or a matte screen for your device.
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.
But is dark mode more comfortable for your eyes? Dark mode successfully cuts glare and reduces some blue light, both of which increase visual comfort. However, dark mode isn't for everyone, and in some cases, it can actually cause more vision problems than solutions.
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. And as we believe in Dodonut, every little action matters in improving the world.
A smartphone can save about 39 to 47 per cent of battery power at peak brightness by operating on dark mode.
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.
It can potentially lessen eye strain in low-light conditions. Suitable for low-light conditions, especially when you don't want your phone to be a beacon of light, e.g., in bed or a cinema. Preferably to light mode before you sleep because it emits less 'blue light.
Blue light comes from the full light spectrum, so you're exposed to it when you're outdoors going through your day. But, when you're at home – at night, in the dark – there are high levels of blue light emitted from your digital devices. As the eyes are exposed to blue light, the retina breaks down.
With over 80% of users operating their devices in dark mode, the data indicates that usage of dark mode has significantly increased. A recent study found that 81.9% of people use the dark mode on their phones, and 82.7% of survey respondents said they use the dark mode on their operating system.
Open your device's Settings app . Select Accessibility. Under "Color and motion," turn on Dark theme.
Dark mode setting has become an increasingly popular battery-saving feature in smartphones. But the option is unlikely to make a big difference in extending a phone's battery life as promoted by both Android and iOS, according to a study by Purdue University.
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.
A dark theme uses dark grey, rather than black, as the primary surface color for components. Dark grey surfaces can express a wider range of color, elevation, and depth, because it's easier to see shadows on grey (instead of black).
Low-lighting situations can cause eye strain if the display is too bright, not to mention filling a dark room with a glare that can disturb others. While the initial intent of dark mode was for those low-lighting situations, it's evolved to be the preferred display mode for many in just about all lighting conditions.
Though dark mode may not help to protect vision, it may help you fall asleep more quickly if you often use electronic devices before bed. Using devices emitting blue light at night may increase your alertness, making it harder for you to fall asleep.
Dark mode requires that pupils dilate more often to take in information. This can make it difficult for some people to see details clearly in dark mode. Furthermore, those who suffer from myopia or astigmatism may also experience “halation” when using dark mode.
Astigmatism is a visual condition where there is a refractive error that impedes the eye from focusing light evenly on the retina. This results in objects appearing to be blurry. Light text on black backgrounds creates a visual fuzzing effect for people with astigmatism called “halation”.
Using night mode settings or black themes may be easier on your eyes than looking at bright, white screens. This is especially true in low-light settings like nighttime.
The consensus is that the "non-colours", white and black, and the colours yellow, green, and orange are generally most acceptable. These colours (yellow, green, orange) are in the middle of the visible spectrum (the range of colours that our eyes can detect) and are the easiest for the eye to see.
The dark mode is beneficial as it is less taxing on the eyes than a harsh, brilliant white screen. Using a dark screen, on the other hand, causes your pupils to dilate, making it more difficult to focus on the screen. You must be wondering why dilatation of the eyes makes it more difficult to see.
