Moreover,
Not all uses have same:
Essential
- A study shows that making social networks scroll more eyes than reading an e-book or watching a video. In addition,
- The researchers observed a sharp drop in blinking and increased variation in pupillary dilation. Meanwhile,
- These results highlight the importance of limiting the time spent on screens. Nevertheless,
Looking at your smartphone for an hour may be enough to tire the sight. Nevertheless, But not all content have the same impact. Similarly, According to a new study published in the Journal of Eye Movement Researchscrolling social networks. in other words scrolling, causes more eye fatigue than reading an e-book or watching a longer video.

Social networks, ocular fatigue champions – Not all uses have same
To better understand the effects of prolonged exposure to screens, researchers have followed 30 young not all uses have same adults in India, a country where the use of the smartphone is very widespread. Each participant used a smartphone for an hour for three separate activities: reading e-books. watching videos and navigation on social networks.
Scientists have developed a portable eye surveillance system based on a Raspberry Pi (a nano-computer) and an infrared camera. This device made it possible to measure precise indicators in real time such as the frequency of blinking. the dilation of the pupils or the intervals between two blinks.

.
The results are final: “The constant changes of content and brightness during navigation on social networks lead to greater eye fatigue”underline the researchers in a press release. Additionally, The dilation of pupils varied more during the scrolling of social networks than when reading or watching videos.

A public health alert
Another observation: a decrease of 54 to 61 % of not all uses have same the air conditioning rate after an hour, and an increase of 39 to 42 % of the interval between two blinks. These two indicators are directly linked to visual fatigue. “Our portable system offers an affordable way to monitor and treat this growing health problem”add the authors.
While most previous studies brought to short durations (3 to 15 minutes), this research better reflects the real use of smartphones. And an hour of screen is nothing compared to the time that many devote to it every day. These new data may inspire public health campaigns aimed at reducing the use of social networks on mobile. Because failing to be able to completely disconnect, it is better to adopt more protective habits for our eyes.
