Sports and Vision: The King-Devick Test
Our ability to have good eye coordination (eye tracking, focusing, etc.) affects more than our ability to read and work on a computer. Eye coordination can also affect our sport performance. The most common effect of poor visual coordination on athletic performance is on depth perception. Depth perception comes from the ability of the two eyes to coordinate together. In fact, depth perception is the primary reason for having two eyes. Dr. Winters explains “A lot of people don’t realize they have depth perception issues until they’re trying to catch a ball. Catching a ball requires a high level of depth perception. If they do have an issue, often this makes it apparent.”
A couple of years ago, the team at WAVTC put together a sports clinic. They worked with a young baseball team for two weeks and trained the team on eye coordination. After the two weeks, many of the participants commented on how much it had improved their game. Athletes that have done vision therapy will talk about how therapy tends to slow the game down for them. Vision therapy helps athletes visualize the ball and other players much better. Edgar Martinez played for the Seattle Mariners for 18 years and is currently their hitting coach. He is known to have done vision therapy, which directly affected his baseball game.
One of the biggest issues facing vision experts has to do with the lack of information the public knows about the risk that trauma can cause to vision. Even mild trauma, let alone concussions, can cause headaches, double vision, loss of place when reading, and overall feeling of being overwhelmed with one’s vision. Luckily, there’s a relatively new eye-tracking test called the King-Devick test. Experts are finding the test to not only be incredibly effective in detecting some vision issues but also a powerful concussion screening test. Dr. Winters encourages sports teams of any age level to learn more about the King-Devick test and its ability to prevent severe damage from head trauma.
