It might sound like a strange concept, but top athletes have long used high-tech computerized visual training programs to give them an edge on the baseball diamond, basketball court and football field. Now Nintendo makes this remarkable technology available to anyone who wants to have fun while tracking improvements in the various visual exercises. It's a great tool for moms who like to keep a "peripheral vision" watch on their kids or for people who want an edge spotting holiday sales.

The first time users pop in Flash Focus: Vision Training in Minutes a Day, they take a series of tests to determine their DS Eye Age. As users spend a few minutes each day with the activities, they get better and better at the exercises and their Eye Age lowers to demonstrate their improved focus abilities.

Features:

- A variation of the hidden ball "hat dance" seen at baseball parks: A circle is placed in one of three boxes, and the user must follow the location of the circle as the boxes shuffle rapidly on the screen.

- Watching two symbols flash on the screen, then tapping the touch screen to indicate whether they matched.

- Memorizing a target letter and counting how many times it appears in a fast-moving stream of letters on the screen.
