It’s All in the Eyes: How Eyesight Can Make or Break an Athlete’s Career

CTECH by Catalyst: Ouriel Daskal0 4.05.19

Good vision can be much more crucial for an athlete than particularly strong lungs or the ability to run very quickly, according to Daniel Laby, an optometrist focused on eye care for professional athletes. In recent years, every sports field has been meticulously analyzed to figure out which aspects of the game, the match, or the athletes can be improved, and if so, how.

Technological advancements now allow researchers to utilize fragments of data in order to create better athletes. This also lets teams assess the strengths and weaknesses of each athlete and pinpoint the ones that have meaningful advantages. Sports vision, a relatively new field of vision care aimed at improving the abilities of athletes, is one such too .

IU, baseball team partner for vision training study

By MICHAEL RESCHKE, The Herald-Times May 23, 2019 Updated: May 23, 2019 10:28 a.m.

Vision training regimens have been around, at a clinical level, for at least 30 years, Port said. They have grown in popularity, especially during the past 15 years, as the cost of computers and other related equipment has decreased. However, no one had tried to do a systematic, rigorous study of the effectiveness of these methods. 

Greg Appelbaum, an associate professor of psychiatry and behavioral sciences at the Duke University School of Medicine, wanted to change that. Appelbaum was familiar with Port's work on concussion testing in athletes and reached out to him. Appelbaum already had a grant from the U.S. Army Research Office for a related study. He pitched adding the vision training study on to that and the Army provided Port with about $24,000 for his portion. "They have an interest in vision training to make better soldiers," Port said. Last fall, the two researchers conducted a pilot study with baseball players at Duke and IU. Players in Bloomington went to the Rink Center for Sports Medicine and Technology at Memorial Stadium three times a week for nine weeks.

The vision training involved three devices: a light rail, strobe glasses and sensory tablets. To measure effectiveness, players went through five days of batting practice at Bart Kaufman Field before and after the vision training. So far, the training seems to have had a positive impact, Port said, but it will be another year before the results are published. "We need to repeat this with a larger sample size," Port said. In addition to baseball players, Port said, the IU softball team has agreed to participate in the study next fall. Understanding how to effectively and efficiently improve a player's hand-eye coordination could help Mercer achieve that goal. "If it works, this could be a fundamental part of our program for the next 20 years," he said.p> 

Warriors' Stephen Curry fixed his vision

Thursday, April 4, 2019 OAKLAND, Calif. (KGO)

Golden State Warriors star Stephen Curry, who is considered one of the greatest three-point shooters in NBA history, has struggled with an astigmatism and not been able to see clearly his entire career. He's been shooting all those three-pointers with blurry vision. How insane is that?? Curry suffers from a cornea condition called Keratoconus, a disease where the cornea thins over time and begins to change from its natural circular shape to one similar to a cone. The cone shape deflects light as it enters the eye and causes blurred vision. While regular vision can be corrected with glasses, they are ineffective for people with Keratoconus because of the irregular, cone shape of the cornea. Moderate Keratoconus can be corrected with a special type of contact lens.
