Video games may help adults' eyesight

March 30, 2009 The study done at the University of Rochester found playing the video games improved contrast sensitivity in adults and even seniors for months and in some cases years.

Contrast sensitivity is the ability to notice minor changes in shades of grey against a uniform background and is important for night driving or in low visibility conditions. It is negatively affected by aging.

The study is published online in the journal Nature Neuroscience.
