Is dark mode on electronic device screens good for your eyes?

Due to advanced technology and increasing screen time, taking care of our visual health is becoming more crucial. One topic that sparks interest among electronic device users is dark mode. More and more applications and operating systems offer this option, but is it truly better for our eyes? 

The question of whether dark mode is genuinely beneficial for our eye health is a significant one to explore. In this article, we will focus on examining the potential advantages that dark mode could offer to our eyes and evaluate whether it is indeed superior to the traditional light mode.


What is the difference between the light mode and the dark mode?

 Before delving into discussing the benefits of dark mode, it's important to understand the fundamental difference between light and dark modes. Light mode, the default setting for most devices, features a bright background and dark text. On the other hand, dark mode reverses this color scheme, presenting a dark background with light text. Both modes have their merits and depend on user preferences, but the dark mode is gaining popularity due to its potential benefits for our eyes.


 3 reasons why using dark mode is better for your eyes

1. Dark mode reduces blue light

Exposure to excessive blue light is a primary factor that can lead to various eye-related health issues. An excess of blue light can contribute to eye fatigue, dryness, irritation, and sleeping difficulties. In the digital era, where we spend increasingly more time in front of electronic screens, this is particularly important.

Dark mode on electronic devices offers a solution by reducing emitted blue light. Presenting a dark screen background, dark mode decreases the amount of blue light reaching our eyes. Light text on a dark background provides contrast and readability while limiting the intensity of blue light affecting the retina.

Dark mode's reduction of blue light contributes to easing eye strain and fatigue. Eyes tend to function more naturally and relaxingly with reduced blue light exposure. Diminished blue light intensity allows the eyes to unwind and regenerate, enhancing overall well-being and eye health.

Applying dark mode can be especially beneficial in the evening when we prepare for sleep. Continuous blue light emission signals our brain that it's daytime, suppressing melatonin production, the hormone responsible for regulating sleep-wake cycles. Using dark mode in the evening and before sleep can help limit blue light exposure, promoting melatonin production and preparing our body for sleep.


2. It is easier to read compared to light mode

The dark background in dark mode, combined with light text, offers numerous benefits for reading on the screen, especially in low lighting conditions. The contrast between the dark background and light text in dark mode results in improved readability, contributing to reduced eye fatigue.



Compared to light mode where bright backgrounds and dark text dominate, dark mode reverses the color scheme, presenting light text on a dark background. This contrast between text and background in dark mode ensures clearer contours and better separation, facilitating content readability on the screen. Eyes have an easier time identifying letters and characters, leading to reduced eye strain and enhanced comfort during reading.

While reading in dark mode, eyes don't need to strain as much to focus on the text. The dark background acts as a neutral plane that allows focus on the content. As a result, eyes experience less effort and strain, which benefits both short and prolonged reading sessions.


3. Dark mode can enhance energy efficiency and battery lifespan

Another beneficial aspect of dark mode is its impact on the battery energy consumption of electronic devices. The dark background requires less screen brightness, potentially leading to lower energy usage for screen backlighting. Consequently, the battery can maintain its charge for longer, which proves particularly useful for mobile devices. Extended battery life means less frequent recharging, enhancing user convenience.

Introducing dark mode to electronic devices has the potential to improve eye health by reducing blue light, facilitating reading, and conserving battery energy. Choosing between light and dark modes depends on user preferences, but it's worthwhile to test dark mode and observe its effects on our well-being and visual comfort. Remember that safeguarding eye health is crucial in the digital age, so experimenting and adjusting device settings to our needs is essential.


Is using dark mode enough for the health of your eyes?

Although dark mode has certain benefits for visual health, it's worth considering whether simply using this feature is enough to ensure optimal comfort and eye protection. There are several factors to take into account and complement the use of dark mode with other practices to guarantee the best conditions for our eyes.

Furthermore, let's not forget about proper eye hygiene. Taking regular breaks from the screen, moisturizing your eyes with artificial tears or lubricating drops, as well as maintaining adequate hydration levels in your body, all of these can contribute to overall visual health. Taking care of our eyes should be a holistic approach that combines the use of dark mode with other beneficial practices.


How can you protect your eyes besides using dark mode?

The best way to shield your eyes from the harmful light emitted by screens and monitors is by using blue light blocking glasses.

The primary benefits of using such glasses are:

  • Reducing blue light exposure
  • Protection against UV radiation
  • Enhanced contrast and screen content sharpness
  • Improved sleep quality
  • Prevention of migraines and headaches
  • Safeguarding the retina of the eye

Blue Light Blocking Glasses


If you spend a lot of time in front of a computer or television during the day, or your work requires using a laptop for many hours, Day NoBlue glasses are the perfect solution for you.





Switching your electronic devices to dark mode is insufficient to adequately protect your eyes. The best choice here would be the Night-time NoBlue glasses, which block 100% of blue light, providing complete protection against harmful blue light. They also reduce stress hormones and effectively support falling asleep and improving sleep quality.
                                                                                                                                In summary, dark mode on phones and other electronic devices has its benefits, but it is not sufficient on its own to protect our eyes. Therefore, it is recommended to use both daytime and nighttime blue light-blocking glasses for comprehensive eye protection.
