Effects of digital game type on visual response

Abstract

While digital games have recently been used to train children with amblyopia, concerns remain about the effects of prolonged gameplay on visual function, including myopia, eye strain, and strabismus. In this study, we compared the effects of different types of digital games on visual responses by examining temporal changes in refraction, accommodation, pupil diameter, and ocular deviation after one hour of play and a subsequent 15-minute break. Three game tasks with distinct eye movement patterns were used. The results showed reversible myopia and increased accommodation in the fighting action game, suggesting that the load on visual function varies depending on the type of digital game. The degree of visual function load may vary depending on the type of digital game. When utilizing digital games in amblyopia treatment, it is essential to deepen the understanding of their potential challenges and to appropriately adjust play duration and the timing of breaks.
