Japanese researchers have published a small study about a virtual reality video game that can reportedly improve players’ eyesight instead of damaging it.

Video games and staring at digital screens in general have long been associated with eyesight problems, but according to a study published by researchers from Kwansei Gakuin University’s Graduate School of Science and Engineering, in certain circumstances, video games can actually help treat short-sightedness (myopia). The researchers had a group of 10 people play a very simple VR video game at certain intervals over a period of six weeks to see how it impacted their eyesight. After analyzing the results, they concluded that even participants who had only played the game at three-day intervals showed measurable eyesight improvements compared to the start of the study.
