High Tech Training Improves Vision

High Tech Training Improves Vision Many believe the most difficult activity in sports is hitting a baseball travelling 80–90 miles an hour. To accomplish the task a person must have excellent eyesight and a reaction time of one- to two-tenths of a second.

New research discovers that with a little practice on a computer or iPad — 25 minutes a day, 4 days a week, for 2 months — our brains can learn to see better.

The proof of the training was demonstrated in a study of University of California, Riverside, baseball players and reported in the journal Current Biology.

The new evidence also shows that a visual training program can sometimes make the difference between winning and losing.

According to researchers, the study is the first to show that perceptual learning can produce improvements in vision in normally seeing individuals.

“The demonstration that seven players reached 20/7.5 acuity — the ability to read text at three times the distance of a normal observer — is dramatic and required players to stand 40 feet back from the eye chart in order to get a measurement of their vision,” said neuroscience researcher Dr. Aaron Seitz of UC Riverside.

For reference, 20/20 is considered normal visual acuity.

“In the training game, the players’ task was to find and select visual patterns modeled after stimuli to which neurons in the early visual cortex of the brain respond best,” Seitz explains.

As game play commenced, those patterns were made dimmer and dimmer, exercising the players’ vision as they searched.

“The goal of the program is to train the brain to better respond to the inputs that it gets from the eye,” Seitz said.

“As with most other aspects of our function, our potential is greater than our normative level of performance. When we go to the gym and exercise, we are able to increase our physical fitness; it’s the same thing with the brain. By exercising our mental processes we can promote our mental fitness.”

After the two-month training period, players reported “seeing the ball much better,” “greater peripheral vision,” “easy to see further,” “able to distinguish lower-contrasting things,” “eyes feel stronger, they don’t get tired as much,” and so on.

The players also showed greater-than-expected improvements in their game. They were less likely to strike out and got more runs. The researchers estimate that those gains in batting statistics may have given the team an additional four or five wins in the 2013 season.

The researchers are now extending their work to include different groups, including members of the Los Angeles and Riverside Police Departments and people with low vision due to cataracts, macular degeneration, or amblyopia. They will also apply the same principles to other aspects of cognition, including memory and attention.

It all comes down to one thing: “Understanding the rules of brain plasticity unlocks great potential for improvement of health and wellbeing,” Seitz said.
