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.
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.
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.
Dark mode extends battery life
They got a 33% increase in battery life just by switching to dark mode. The researchers point out that only smartphones with OLED screens will get the benefit of extended battery life.
Ultimately, visual performance tends to be better with light mode for most people. However, some people with cataracts and related disorders may prefer the visuals provided in a dark mode.
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.
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.
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 %.
Though it does use less battery than a regular light-coloured theme, the difference is unlikely to be noticeable “with the way that most people use their phones on a daily basis.
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.
Studies show most people have better reading performance when using a light theme. However, a dark theme offers some advantages, such as retaining night vision, extending battery life on a mobile device, and perhaps looking more aesthetically pleasing.

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. For those of you who've lived in a place like Seattle before, you know what I'm talking about.
In fact, it could make eye strain more likely for certain individuals. 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.
On your phone, open the Settings app. Tap Display. Turn Dark theme on or off.
People who use dark mode also state that it helps them fall asleep easier. The use of dark mode is gaining more popularity due to raised awareness about its possible health benefits. These are mostly related to better sleep, reduced harmful blue light exposure, and relief from eye strain.
Dark mode is often touted as a way to reduce your exposure to sleep-disrupting blue light to encourage a better night's sleep. And some say, too, that it can reduce the strain on your eyes and make using your device more comfortable. But while it may be helpful, it's not necessarily a cure-all.
It showed that dark mode only saves energy if your phone is on the brightest setting instead of auto brightness. If you're on auto brightness, dark mode only saves a negligible 3 to 9 percent of battery.
Having night mode on during the day won't cause any increased damage to your eyes and if anything, may be beneficial as you're much more bombarded with blue light (HEV waves) during the day. Having night mode during the day for multiple days WON'T cause eye problems.
Keeping your screen at full brightness all the time can really drain your battery, so it's a good idea to turn your screen brightness down to a level that allows you to comfortably use your phone while preserving your battery.
A dark screen mode is a measure to avoid those unpleasant and irritated eyes that are normally a product of the bright white screen, as the human generation has found comfort in spending nearly 11 hours a day attached to their phone screens. The improved life of the battery is another benefit of the 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.
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.
There is no evidence to prove that dark mode helps relieve eye strain or protects your vision in any way. However, dark mode may help you sleep better if you are accustomed to using electronic devices before bed.
