Ammon News - Dark mode has become increasingly popular recently, with most companies integrating a dark mode option into their websites. While many studies claim that using dark mode may reduce eye fatigue and cut back on blue light exposure, there has been an ongoing debate on dark mode vs light mode.

So, is dark mode better for your eyes or it’s just a UX trend? Before reaching a conclusion, let’s learn more about this trending feature and closely examine various scientific findings.

What is dark mode?
Dark mode is a display option for digital devices that enables a dark background with lighter text (negative contrast polarity) to reduce the amount of blue light emission.

The primary reason behind using dark mode or dark theme is to offer a comfortable viewing experience, especially in low-light conditions. Most popular websites like YouTube and Google have now embraced this feature and provide the option to choose the dark theme from settings.

What are the benefits of dark mode?
A recent statistic shows that people have 6 hours and 58 minutes of screen time per day on average. This alarming increase in average screen time comes with severe effects on our vision and causes fatigue and other diseases including Computer Vision Syndrome (CVS).

The blue light that emits from digital devices is considered one of the key reasons behind such eye conditions. In this regard, the default black background that comes with dark mode may have a good impact as it reduces blue light (a type of high-energy visible light) exposure and can improve screen time.

Also, texts appearing on a dark background have more contrast and can reduce strain on the eyes.

Another popular benefit of the dark mode is increased battery health. Especially on an OLED screen dark mode can significantly improve your battery health.

Is dark mode better for your eyes?
Several pieces of research over the years have found the dark mode to have positive effects on our vision, resulting in reduced eye strain and better visual comfort. In addition, dark mode helps significantly to reduce screen glare mostly in dark environments.

What does the research say?
A group of researchers from the University of Central Florida found a significant increase in visual acuity and reduced visual fatigue using dark mode. The research was conducted on head-mounted displays and the dark mode was favored among the participants in complex and low-light backgrounds.

Another study published in the Ergonomics journal found that younger age groups showed more positive emotions while using dark mode and preferred it for aesthetic reasons.

An article from the American Academy of Ophthalmology recommends setting devices to dark or night mode in the evening to reduce exposure to blue light. The lower screen brightness and warm colors of dark mode help our bodies to think it’s nighttime and it can help us get a night of good sleep.

Although these studies present the possible benefits of dark mode for eye health, there is still no concrete evidence of the impact of dark mode on improving eye conditions. Most of such research is still in the early stage and is likely to provide better results in the future.

So, it’s important to use dark mode in moderation and find the best possible way to comfort your eyes.

The benefits of dark mode for eye health and other use cases
There are many practical benefits of dark mode related to eye health including reducing eye strain, cutting down blue light exposure, and making text legible. In addition, it can also help us concentrate and save our battery.

1. Dark mode helps reduce eye strain
In a dark environment, our eyes tend to work extra hard when looking at a bright screen. Enabling dark mode can prevent that and add comfort to our eyes.

2. Dark mode may cut down blue light exposure
Blue light is considered a culprit behind conditions like dry eyes and blurred vision. It also influences our sleep cycle and can prevent us from getting sufficient rest if we expose ourselves to it before bedtime. Dark mode can prevent such exposure and provide us with a good night of sleep.

3. Dark mode makes the text more legible
While thinking about readability, text tends to pop out more in a dim background. The high contrast ratio between a dark background and light text can make it easier to read texts, especially in low-light situations.

4. Dark mode improves concentration
When we work on a computer or mobile device without break, our eyes get tired and we experience complications like headaches, and eye strain and eventually interrupting our concentration. In such cases, dark mode is known for reducing screen glare and improving focus.

As the texts appear more prominently on a dark background, the contrast ratio alone helps us concentrate more on the content visible on our screen.

5. Dark mode saves battery life
According to a study conducted by Purdue University in 2021, on OLED screens dark mode can save around 39% to 47% battery life while keeping the phone at maximum brightness. So it’s an excellent choice for someone conscious about their battery health.
