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

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 research showed that people who played action video games for a few hours a day over the course of a month improved their vision by about 20 percent. That would pretty much put me back where I was before I ditched the newspaper world to become … Read more

OK, before you start laughing, consider how your parents might use a computer as they get older--and even yourself, for that matter. The "Vision Board II" is a keyboard that would make life substantially easier for a person whose eyesight isn't what it used to be, similar in concept to phones with large numbers.

Not only are they more legible, but Uber-Review says the 1-inch-square keys also reduce the chances of mistyping because they're nearly twice the size of normal ones. The "F" keys are designed in a distinctive oval shape to make it … Read more
