Study: Playing Video Games Could Improve Cataracts in Young Patients

New research suggests playing video games can actually improve the vision of young patients who are nearly blind, according to a Daily Mail report.

For the study, patients aged 19-31 who had cataracts in both eyes at birth and whose vision did not return to normal after having cataract surgery, played 10 hours of video games for four weeks. After 40 hours, patients could see further down the eye chart, were better at distinguishing the direction of a movement and could tell faces apart.

The research also showed action games, where patients took on the roles of soldiers shooting the enemy or gunmen firing at aliens, improved vision more than simpler games such as Tetris because of the subtle changes in color and large amount of visual information that needs to be processed.
