Abstract. Video games are one of the most common reasons for using various digital devices for entertainment purposes. The aim of our study was to examine the effects of video games on vision through an analysis of the available literature on the subject. The majority of studies have focused on the consequences of digital visual strain from the use of video displays such as burning, irritation, tearing, dryness, discomfort, eye pain and headaches. In childhood, video games can lead to increased frequency of tics, double vision and dizziness associated with tracking fast-moving objects and the need to play without rest to advance to the next level. However, many studies show that playing video games also has positive effects such as improved contrast sensitivity, shorter saccade reaction time, higher spatial resolution of vision, faster visual- motor brain activity, improving visual attention and even expanding the field of vision. Results are promising in treating lazy eye in both children and adults. Limited use of video games as a means of entertainment is required due to the risk of addiction and visual strain. Of course, we should not forget their potential positive effects, for which additional studies are needed.
Key words: video displays, digital strain, addiction, amblyopia
