Better performance on vision tests like counting flashing dots was associated with better catching.
Vision skills can lead to sports success, research claims
by: Martha Finnegan Bradford
The Irish Times (9/9/2015)
Researchers tested elite athletes such as rugby players, as well as sporty members of the general public and people who don’t play any sport.
Better performance on vision tests like counting flashing dots was associated with better catching, even under challenging visual conditions.
Some elite sportspeople performed poorly, so this is not the be all and the end all of sports performance, but it might be the extra one per cent that could win the game.
What’s not clear is whether this is an innate talent or something that developed over thousands of hours of practice.
Research has been scant on correlation between officiating and visual performance; new study shows
Why standardized vision testing, training crucial for sports officials

Ophthalmology Times (4/15/2014)
Most calls by officials require correct quality of visual information. A critical call might be the difference between winning and losing for a team. Other visually based studies performed on athletes—including tennis, volleyball, and baseball—have shown that superior athletes possess superior skills. Research has shown that these visual skills, besides eyesight, can be measured and trained.
Officials have similar visual demands as athletes. Therefore, officials should have visual skills comparable to athletes. An official needs not only to be physically fit but also visually fit.
There are many examples of officiating calls that require superb visual perception:
- Both feet or one foot inbounds?
- Ball on one side of the goalpost or through the center?
- Spike hit the line?
- A 130-mph serve in or out?
- Player offside?
- Baseball hit the yellow wall line or not?

Athletes across the globe, whether professional, amateur or recreational, are embracing new technologies and training methods to boost their performance. But while they lift weights, train in wind tunnels, adhere to strict diets and spend countless hours perfecting techniques, they often overlook one crucial body component: their eyes.
Recent studies are definitive: Athletes with superior vision skills perform better on the playing field. Until recently, however, no quantitative, interactive programs existed in the world of vision training. A U.S.-based company, Vizual Edge, is working to revolutionize the vision training game.
Degrading the visual acuity of sport officials significantly impairs ability to make correct calls
The Effect Of Visual Acuity Degradation On The Visual Judgement Of Sport Officials

Department of Kinesiology, Texas A&M University-Corpus Christi, TX (5/7/2013)
PURPOSE: The purpose of this study was to investigate the effect of visual acuity degradation on the visual judgment of sport officials. Visual acuity was analyzed by a standard visual acuity wall chart. Visual judgment was determined by a tennis ball line test where subjects have to determine if balls are classified as "in" or "out".
RESULTS: A paired-samples t test was calculated to compare the mean pretest (normal vision) score to the mean posttest (degraded vision) score. The mean on the pretest was 25.73 (sd = 2.16), and the mean on the posttest was 16.91 (sd = 3.22). The results of the paired-samples t test determined a statistically significant difference between the pretest and posttest scores (t(21) = 2.69, p < .05). CONCLUSION: The results of this study indicate that degrading the visual acuity of sport officials significantly impairs their ability to make correct line calls.
Study indicates that superior visual skills were highly related to superior volleyball performance
The Relationship Between Visual Skills and Volleyball Performance of NCAA D

The results of Sport Science Research Laboratory study indicates that superior visual skills were highly related to superior volleyball performance statistics in several areas. Since visual skills appear to play a crucial role in volleyball performance, coaches may consider using programs such as VEPT to assess volleyball players.

Vision training for athletes evolved from reading therapies developed decades ago to help children
A Little Flabby Around the Eyeballs
by: GRETCHEN REYNOLDS
New York Times (2/5/2006)
Vision training for athletes evolved from reading therapies developed decades ago to help children with learning disabilities and people with amblyopia ("lazy eye") concentrate and follow lines of text. Unlike exercises designed to strengthen eye muscles, reading therapy works to improve the eye-brain connection. Sports vision therapy takes it one step further. "It's about eye-hand-foot-body-brain coordination," says Dr. Barry Seiller, an ophthalmologist who is Brett Basanez's vision specialist and the director of the Visual Fitness Institute in Vernon Hills, Ill. "Maybe you foul off the ball a lot, or you have all the technical skills but somehow just can't put it together. You go into slumps. You fail in the clutch. All of that, to us, screams 'visual problems."'
