科学｜内斜視の増加とスマホの関係 / Science | The Relationship Between the Increase in Esotropia and Smartphones

Summary

According to the results announced by a research team at Kyoto University, the sharp increase in cases of “esotropia” (crossed eyes) is found to be only minimally influenced by the widespread use of smartphones.

In particular, while excessive smartphone use has been considered a cause of “smartphone-related esotropia,” the study suggests that individuals predisposed to this condition may trigger it by constantly focusing on nearby objects. These findings have been published in an international academic journal.

Dialogue

This dialogue is fictional and based on the article.

Chako: Hey Log, I heard that the number of people with esotropia has been increasing lately, and they’re saying it’s due to smartphones! What do you think?

Log: Well, it’s true that excessive smartphone use was thought to be a contributing factor, but recent studies suggest that its impact might be limited.

Chako: Oh really? What does that mean?

Log: It means that people who are prone to esotropia may be more likely to develop it from focusing on nearby objects for extended periods. So, smartphones aren’t the only cause.

Navi: To add to that, research indicates that for esotropia patients, smartphone use is not the primary factor; rather, it is believed to be related to their inherent predisposition.

Admin’s Note

I believe that the results of this study provide a great opportunity to deepen our understanding of the smartphones we use daily. It’s particularly important to note that the impact of smartphones is not the only factor at play. The finding that continuously looking at nearby objects can influence the development of convergence insufficiency highlights the importance of managing our vision in everyday life. To protect our eye health, taking regular breaks and shifting our gaze is essential.
