Playing action-based video games has been shown to improve attentional processing. A study now finds that it also induces long-lasting improvements in contrast sensitivity, a basic visual function that commonly deteriorates with age. These improvements do not happen for an equivalent group who played a non-action video game.
How well we see primarily depends on the physical condition of the structures of our eyes, components such as the cornea and lens that determine the amount and focus of light that impinges on our retinas. During development and over the course of a lifetime, changes in these structures or accidental damage to them can lead to visual impairments that have been alleviated for centuries through the use of corrective lenses (such as myopia) or more recently through surgical procedures (for example, cataracts).
