Study: Video Gaming May Aid Eyesight

Playing action video games may help adults improve their eyesight, according to a study released Sunday, March 29, 2009.

People who used a video-game training program saw improvements in their contrast sensitivity, or the ability to notice subtle differences in shades of gray, according to a study published in the journal Nature Neuroscience. The training could be beneficial to people who have amblyopia — commonly known as lazy eye — and those who have trouble seeing while driving at night, the study said.
