Playing action video games can boost an aspect of adult vision previously thought to be fixed, a US study shows.
Researchers found playing the games improved the ability to notice even very small changes in shades of grey against a uniform background.
"Contrast sensitivity" is important in situations such as driving at night, or in conditions of poor visibility.
The Nature Neuroscience study raises the possibility of using a video game training regime to improve vision.
