A new study has raised alarms over the growing issue of eye strain among young adults, showing that the type of digital content consumed plays a significant role in eye health. According to research published in the Journal of Eye Movement Research, young people who spend even a single hour on their smartphones, particularly browsing social media reels, experience measurable eye strain.
The study monitored 30 young adults in India, each in their early 20s, who had been using smartphones for at least a year. Participants’ daily screen time averaged more than five hours, and 98% reported using their smartphones before bed—mostly to consume social media content. Using a real-time eye monitoring system, researchers tracked blink rate, inter-blink intervals, and pupil size during three separate screen sessions: reading an ebook, watching a video, and scrolling through social media reels.
Social Media Reels: The Most Straining Content
Findings revealed that social media reels were far more taxing on the eyes than ebook reading or traditional video watching. The rapid, ever-changing visuals and fluctuating screen brightness typical of platforms like TikTok and Instagram demanded frequent visual adaptation, resulting in larger average pupil diameters and increased signs of eye strain. For example, the pupil diameter during social media sessions was 5.14mm, compared to 4.23mm for ebooks and 4.36mm for videos.
The study also reported that 83% of participants experienced psychophysiological issues—such as anxiety, sleep disruption, and mental fatigue—while 60% reported physical discomfort, including eye strain and neck pain. Despite these symptoms, about one-third admitted to using their smartphones continuously for more than 20 minutes at a time.
Practical Steps for Digital Eye Wellness
Researchers emphasize that small behavioral changes can make a significant difference:
-
Limit exposure to fast-paced, dynamic content like social media reels.
-
Take a 20-second break every 20 minutes while using digital screens.
-
Use features like blue light filters or dark mode, and try to avoid screens before sleep.
Opting for more stable, less visually demanding content can help ease eye strain, the study suggests. As screen time among young people continues to rise, experts urge adopting healthier device habits to protect long-term eye health.earth
