Browser Terms Explained: Dark mode

In recent years, dark mode has gained popularity among technology users as an alternative visual display mode. Dark mode is no longer just an aesthetically pleasing feature, but also an essential part of many people's daily routine. This article will attempt to explain everything you need to know about dark mode, including its history, benefits, how it works, customizing settings, and comparisons with light mode.

Understanding Dark Mode

What is Dark Mode?

Dark mode is a display mode option for screen-based devices, including computers, smartphones, and tablets, that replaces the traditional light background with a dark-colored surface. The color of the content changes from dark text on a light background to light text on a dark background.

One of the most popular uses of dark mode is for social media apps, such as Twitter, Instagram, and Facebook. These apps offer the option to switch to dark mode, which many users find easier on the eyes, especially when scrolling through their feeds for extended periods.

The History of Dark Mode

The concept of dark mode dates back to the 1970s when the first computer displays were being developed. The original displays had a green or amber background with light-colored text. In the early 2000s, the concept of dark mode resurfaced when software developers introduced the alternate visual display option as an accessibility feature for users with visual impairments. By 2010, web developers were using dark mode as a design element in some websites, and soon it became a built-in feature in some operating systems.

Today, dark mode is available on most popular operating systems, including iOS, Android, macOS, and Windows. Many apps and websites also offer the option to switch to dark mode, making it a ubiquitous feature across the digital landscape.

Benefits of Using Dark Mode

While the majority of people tend to use dark mode for aesthetic purposes, it also offers several benefits, including:

  • Reducing eye strain and fatigue caused by blue light

  • Improving battery life on devices with OLED or AMOLED displays

  • Preventing glare in poorly lit environments

  • Providing a more immersive viewing experience

Studies have shown that blue light emitted by screens can disrupt our circadian rhythms and interfere with our ability to fall asleep. By using dark mode, which reduces the amount of blue light emitted by screens, users can potentially improve their sleep quality and reduce the risk of developing sleep-related disorders.

In addition to the health benefits, dark mode can also be more energy-efficient, especially on devices with OLED or AMOLED displays. These displays can turn off individual pixels when displaying black, which can lead to significant power savings and longer battery life.

Overall, dark mode has become an increasingly popular feature across digital devices and platforms. Whether it's for aesthetic or health reasons, users can enjoy the benefits of this feature and customize their digital experience to their liking.

How Dark Mode Works

Dark mode is a popular feature that changes the color scheme of web pages and apps to a darker color palette. It has gained popularity in recent years due to its numerous benefits, including reducing eye strain, improving readability in low light environments, and saving battery life on devices with OLED screens.

Dark Mode in Different Browsers

Dark mode works differently in different browsers. Some browsers, including Google Chrome and Microsoft Edge, have built-in dark modes that change the color scheme of web pages automatically. This means that users don't need to install any additional add-ons or extensions to enable dark mode on these browsers. On the other hand, some browsers, including Firefox and Safari, require users to install extensions or enable it manually.

Enabling dark mode in Firefox is relatively easy. Users can go to the settings menu, select "Add-ons," and search for "dark mode" to find the relevant extensions. Once installed, users can toggle between light and dark mode using the extension's icon on the browser toolbar. Similarly, users can enable dark mode in Safari by going to the "Preferences" menu and selecting "General" and then "Appearance."

Dark Mode Extensions and Add-ons

Users who prefer to use dark mode on their browsers can install add-ons or extensions that allow them to switch between light mode and dark mode visually. These extensions and add-ons are available on various platforms, including the Chrome Web Store, Firefox Add-Ons, and Microsoft Edge Add-Ons. Many of the extensions also offer customized settings such as switching between light and dark mode depending on the time of day or switching only certain websites to dark mode.

For example, the "Dark Reader" extension is a popular choice for users who want to enable dark mode on their browsers. It offers a customizable color scheme, brightness and contrast settings, and the ability to exclude certain websites from dark mode. Similarly, the "Night Eye" extension offers similar features, including the ability to adjust the color temperature and brightness of the screen.

Dark Mode on Mobile Devices

Dark mode on mobile devices is similar to dark mode on desktop browsers. However, there are some differences depending on the operating system, phone model, and apps being used. Some phone models have built-in dark mode functions, while others require users to install third-party apps to enable dark mode.

For example, on Android devices, users can enable dark mode by going to the "Settings" menu and selecting "Display." From there, they can toggle on the "Dark theme" option to enable dark mode. On iOS devices, users can enable dark mode by going to the "Settings" menu and selecting "Display & Brightness." From there, they can toggle on the "Dark" option to enable dark mode.

It's worth noting that dark mode may consume more battery on mobile devices with LCD screens compared to OLED screens. This is because OLED screens can turn off individual pixels to display true black, while LCD screens require a backlight to display colors, even in dark mode.

Customizing Dark Mode Settings

Adjusting Dark Mode Preferences

Dark mode settings differ between devices and operating systems. Users can, however, customize their experience by adjusting the brightness, contrast, and color temperature. Some operating systems also allow users to change the accent color and adjust the transparency of the dark mode to their preference.

Troubleshooting Dark Mode Issues

Some users may experience issues while using dark mode, including blurry text, color inconsistencies, website formatting issues, and compatibility problems. If you experience any problems while using dark mode, try updating your browser or operating system and disabling any installed extensions or add-ons. It is important to note that not all websites support dark mode.

Dark Mode and Accessibility

Dark mode is becoming more common as a built-in accessibility option for users with visual impairments, dyslexia, and sensitivity to bright lights. A combination of high contrast and a dark background can reduce visual stress and make text easier to read. Many third-party apps and browser extensions offer accessibility options that align with the user's needs.

Dark Mode vs. Light Mode

Comparing Visual Impact

Dark mode and light mode offer different visual experiences. Light mode provides a traditional bright background with dark text, while dark mode is a reverse visual experience. In general, dark mode provides a more immersive viewing experience, while light mode provides a clear visual experience.

Energy Consumption Differences

The use of dark mode instead of light mode can have a positive impact on battery life in devices with OLED or AMOLED displays. Dark mode switches off pixels on the screen that are not in use, reducing the amount of battery needed to power the display.

User Experience and Productivity

While most people prefer dark mode for its visual aesthetics, some users prefer light mode because it is easier to read and makes it easier to differentiate between colors. The choice between light and dark mode ultimately depends on individual preferences and the purpose for which the device is being used.


In conclusion, dark mode is a popular display option for many people, and its use will likely continue to grow as technology advances. It offers several benefits such as reducing eye strain, improving battery life, and offering an immersive viewing experience. It's essential to understand how dark mode works and how to customize its settings depending on individual preferences.
