Impact of digital devices on vision

The extensive use of modern digital devices, such as smartphones, tablets, and computers, is leading to a significant increase in ocular and visual discomfort among children, including symptoms like headaches, eyestrain, dry eyes, and sore eyes, as well as accommodative and binocular vision disorders, according to a presentation at Optometry’s Meeting 2024.

During the presentation, “iStrain: What Effects Do Today’s Tablets and Devices Have on Vision?” Valerie M. Kattouf, OD, FAAO, Associate Professor at the Illinois College of Optometry and Chief of the Lewenson Pediatrics/Binocular Vision Service at the Illinois Eye Institute emphasized the need for balanced technology use and practical strategies to mitigate these negative effects on children’s vision and overall health.

Dr Kattouf highlighted several significant findings, noting that the extensive use of handheld devices is associated with a rise in symptoms such as headaches, eyestrain, dry eyes, and sore eyes. These devices alter visual accommodation, resulting in increased lag, decreased amplitude, reduced fusional convergence, and a receded near point of convergence. The presentation emphasized that these visual issues are becoming more common as the use of digital devices continues to grow.

The talk also addressed the psychological impact of excessive screen time, drawing parallels to addictive behaviors and decreased social coping skills. Dr Kattouf pointed out that screen-induced symptoms might even lead to the misdiagnosis of conditions like ADHD.

In her presentation, Dr Kattouf offered practical recommendations for parents and practitioners to help mitigate the negative effects of digital device use. She advocated for balanced technology use in households and proposed the creation of “screen-free” zones, especially in bedrooms and during meals. She recommended limiting screen use to high-quality content and ensuring it is used in moderation. Encouraging outdoor play, reading, and hobbies was also highlighted as crucial for promoting overall well-being.
