Recomendamos fuertemente el uso de VEPT no sólo en los atletas de alto rendimiento
Soy la Doctora Sandra Rossi, médica especialista en Medicina del Deporte, tengo a cargo el Laboratorio de Entrenamiento Visual y Sensoriomotor del Cenard, ( Centro Nacional de Alto Rendimiento Deportivo, en Buenos Aires, Argentina ), soy Directora Médica de ácumen, Primer centro de entrenamiento Visual Físico y Mental del país.
Hace aproximadamente un año, comenzamos a utilizar Vizual Edge en todos nuestros atletas, nuestra mayor cantidad de atletas son pilotos de automovilismo de todas las categorías de nuestro país y de otros países. También entrenamos jugadores de rugby, hockey, tenis, voleyball, trabajamos con muchos seleccionados nacionales y en todos los casos los resultados son extremadamente buenos, no sólo los observados por nosotros ya que un entrenamiento lo hacen en ácumen acompañados por un entrenador, sino que también los que realizan en sus casas, siendo muy fácil el monitoreo de sus progresos.
Los deportistas nos refieren que tienen mejores cálculos de distancia; mejor discernimiento de la profundidad, se sienten más rápidos visualmente y pueden mantener su foco atencional más tiempo, por lo cual recomendamos fuertemente el uso de VEPT no sólo en los atletas de alto rendimiento sino en todas las personas que decidan mejorar su performance.
Es bien sabido que entrenar los ojos es entrenar el cerebro. Cualquier información visual requiere de aproximadamente del 70% del cerebro para poder procesarse, es por esto que al entrenar habilidades visuales, estamos entrenando el potencial del cerebro humano.
Las vía de información visual requieren de centros cerebrales como la atención y la memoria, con lo cual, no se entrena visión periférica, cambios rápidos de foco o discernimiento de profundidad sino que también estamos entrenando la atención y la concentración y la memoria.
Es por esto que recomendamos el uso de VEPT en todas aquellas personas que quieran mejorar su día a día.

Pro Baseball Visual Performance
The Relationship between Visual Skills and Performance of Pro Baseball Players
by: Tim Rodmaker Professional Baseball Strength & Conditioning Coaches Society (11/30/2016)
352 professional baseball players were evaluated for visual skills and batting performance during the 2013 minor league baseball season using the Vizual Edge Performance Trainer® (VEPT), a commercial software program designed to assess eye alignment, depth perception, convergence, divergence, visual recognition and visual tracking.
Vitamins, 3D glasses and strobes are tools athletes are using to see better but does it really work?
Baseball’s New 'Secret Weapon': High-Tech Vision Training
by: Joe Lemire (5/9/2016)
Through the 3-D glasses, the red triangle and blue square just won’t line up. Even when the shapes appear to overlap, the vision training program assures me they did not. One eye perceives the triangle and the other perceives the square and, despite my best efforts with the keyboard arrows, I can’t find their concentric meeting point.
My visual alignment is deemed “fair,” but the descriptive text sounds clinically severe. My score “represents a moderate binocular eye muscle imbalance. The aiming of the eyes is inaccurate.” Basically, my eyes are misaligned after the target, which will result in perpetually late swings.
The evaluation of my eyes’ convergence—the ability to focus on objects in the foreground—is much worse. The test involves staring at a magic-eye stereogram, which I have never been able to do and can’t do now. The program tells me my eyes’ convergence is “extremely limited.”
There’s no putting rose- (and cyan-) colored glasses on this result: my overall vision score put me in the 5th percentile. I will never be a major league hitter.
“We didn’t change his eyesight,” Puchalski said. “We work on the quality of his visual information and how you see things and can react on field.”
That’s the first lesson to learn about sports vision. The realm of sight extends well beyond the lines below the E on an eye doctor’s wall.
A recent issue of Sports Illustrated contained an article about vision performance and baseball. It highlighted the visual training protocol of several players of the Washington Nationals who, along with numerous MLB teams, use the Vizual Edge Program for assessment of player potential and improving visual processing, tracking and pitch recognition.
Strong indication that Vizual Edge Scores correlate to superior performance, study says
The Relationship Between Visual Skills and Performance of Professional Baseball Players
by: Frank J, Spaniol, Ed.D., CSCS*D, FNSCA Sport Science Research Laboratory, Texas A&M University-Corpus Christi (11/20/2013)
The results of this study provides evidence that superior visual skills are indicative of superior batting performance in several statistical categories including BA, SO%, OBP, and OPS. Since visual skills appear to play a significant role in batting performance, coaches, trainers, and administrators should consider using programs such as VEPT to assess baseball players.
Facilities in Europe are incorporating sports vision to help athletes enhance the visual component
Vision performance services offer new area of expansion for ophthalmic practices
by: Dr. Barry L. Seiller, MBA Ocular Surgery News (7/29/2013)
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
by: I. GOMEZ, F. SPANIOL, J. DAWES 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.
NCAA Division I student-athletes possess superior visual skills when compared to non student-athlete
An Evaluation of Visual Skills of Athletes and Non-Athletes
by: Renae Hudak Texas A&M University- Corpus Christi (8/27/2012)
In recent years there has been an increased interest in examining visual skills and athletics participation. The purpose of this study was to investigate the visual skills of student athletes vs. non student-athletes. The research was conducted on NCAA Division I student-athletes consisting of baseball, softball and, volleyball players (n=72), and non student-athletes (n=30), all ranging from the ages of 18-25. Visual skills were assessed by the Visual Edge Performance Trainer (VEPT) software program and included tests for visual alignment, depth perception, visual flexibility, visual recognition, and visual tracking, which resulted in a composite VEPT score. A t-test for independent samples was utilized to analyze the mean VEPT scores of the two samples with an alpha level of .05. The results indicated a significant difference in the two examined groups with a P value at 0.0393. Statistical analysis indicated that that NCAA Division I student-athletes possess superior visual skills when compared to non student-athletes.

Line between success and failure on greens gets blurry with age
by: Diane Pucin Los Angeles Times (1/25/2012)
David Kirschen, an optometrist with an expertise in sports and a member of the faculty at UCLA, said that what many golfers don't understand is how important vision is to putting well. And vision tends to worsen with age.
Kirschen listed acuity — how sharply one sees detail at a distance — as the first component in helping a putter. He also said depth perception and focus matter.
Vision training can combine traditional and technological methodologies to train the athletes' eyes
High-Performance Vision Training Improves Batting Statistics for University
by: Joseph F. Clark PLoS ONE 7(1): e29109. doi:10.1371/journal.pone.0029109 (1/19/2012)
Vision training can combine traditional and technological methodologies to train the athletes' eyes and improve batting. Vision training as part of conditioning or injury prevention can be applied and may improve batting performance in college baseball players. High performance vision training can be instituted in the pre-season and maintained throughout the season to improve batting parameters.
You mean that sports requires activity above the neck? What a shock!
by: Todd Hargrove Better Movement A BRAIN-CENTERED PERSPECTIVE ON PERFORMANCE AND PAIN (5/5/2011)
Sporting ability is to a huge extent dependent on quickly and accurately interpreting visual information. The key word here is interpreting – sports vision is not just accurately seeing what is there to be seen, it is using that visual information to make accurate predictions about what will happen in the next few seconds. In effect, this isn’t really a visual task at all, it is a task of the imagination that uses visual information as the primary data.
Just like any other muscle in the body, extraocular muscles in the eye get stronger with training.
Eyes On The Prize
by: Dr. Michael Zupan & Al Wile Training and Conditioning (3/21/2011)
How much can sports vision training improve an athlete's performance? This is by far the most common question we receive here in the Human Performance Laboratory at the United States Air Force Academy. Unfortunately, we cannot quantify exactly how much sports vision training will increase a baseball player's batting average, a basketball player's shooting percentage, or a goalie's save percentage.

Exercise performance and sports-vision testing under more realistic testin
by: Fowler, K.F., Du Toit, P.J. University of Pretoria Health Sciences Faculty Day (8/1/2009)
Sports vision aims to enhance performance through a variety of procedures and training techniques. An improvement in performance was observed by players exposed to the exercises. Visual abilities can affect both motor skill and performance. This study proves that correct training programs and hand-eye co-ordination tests can vastly improve sporting performance. Athletes are advised to complete at least 15 minutes of sport-specific visual training during each day of practice.
Des clubs de baseball utilisent des logiciels pour améliorer la vision de leurs athlètes.
L'entrainement visuel, l'avenir du sport?
by: Seth Stevenson Slate France (6/10/2009)
Barry Seiller (l'ophtalmologiste qui a conçu le logiciel Vizual Edge en 2002) a réalisé des analyses et des tests d'acuité visuelle pour différentes équipes (les Houston Astros, les San Diego Padres, les Cincinnati Reds et autres Seattle Mariners, Texas Rangers, Milwaukee Brewers ainsi que les hockeyeurs des Chicago Blackhawks); il a fait de même pour quelques programmes de sport universitaires et pour plusieurs sportifs participant aux Jeux olympiques. (Les équipes de bobsleigh développent leur capacité de convergence afin de mieux évaluer les angles d'entrée et de sortie dans les courbes de vitesse des pistes.) «Les athlètes de haut niveau jouissent d'une acuité visuelle développée», si l'on en croit Seiller. Selon lui, rien qu'en analysant les résultats obtenus par des joueurs de la Minor League sur le Vizual Edge, il a souvent pu deviner lesquels auraient les meilleurs moyennes à la batte.
Eyesight shown to improve with the very act of action video game playing
Enhancing the contrast sensitivity function through action video game train
by: Renjie Li, Uri Polat, Walter Makous & Daphne Bavelier Nature Neuroscience 12, 549 - 551 (3/29/2009)
The contrast sensitivity function (CSF) is routinely assessed in clinical evaluation of vision and is the primary limiting factor in how well one sees. CSF improvements are typically brought about by correction of the optics of the eye with eyeglasses, contact lenses or surgery. We found that the very act of action video game playing also enhanced contrast sensitivity, providing a complementary route to eyesight improvement.
Playing action-based video games has been shown to improve attentional processing. A study now finds that it also induces long-lasting improvements in contrast sensitivity, a basic visual function that commonly deteriorates with age. These improvements do not happen for an equivalent group who played a non-action video game.

Vision performance training for athletics had its geneses from students with reading disorders. Scientific study confirms findings of student athletes and their coaches that academics also improves with visual skills training.
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."'

Optometrist helps hitters keep eye on ball
by: Scott Brown Florida Today (3/16/2005)
What does this have to do with hitting a baseball, perhaps the hardest thing to do in all of sports? Everything, if you ask Washington Nationals interim general manager Jim Bowden.
"A baseball's coming in at 95 miles an hour and changing planes. Sometimes it's coming in at 76 miles as a curveball. Sometimes it's an 84-mile-per-hour slider," Bowden said. "All the different speeds, all the different locations, all the different rotations means your eyes have to be phenomenal so you can identify what the pitch is, where the pitch is going to be and whether to swing or not to swing."

Out of Sight
by: Tyler Hass Girevik Magazine (10/22/2002)
Eyesight is one of the most complex actions of the human body. It is one of our most important survival characteristics and crucial for performance in any sport. While the eye is an incredible organ in its own right, the real act of seeing occurs in the brain. This is where visual data becomes the world that we know and interact with. The world's most powerful computers cannot do what our brains do instantaneosly, every moment of the day. The eye is merely the starting point for our amazing visual system.
Training the eyes is not a new idea; improve-it-yourself vision books have been around for years.
On fitness: The Eyes Have It
by: Molly Martin Pacific Northwest magazine (7/28/2002)
I found myself more encouraged - inspired, even - by the tale of Greg Vaughn. San Diego Union sports columnist Tom Cushman called it "the most astonishing turnaround I've witnessed in 30-plus years of covering major-league baseball."
Vaughn has cited two common factors, hard work and more playing time, for helping find his groove this year. But he also credits something that many other athletes - recreational and competitive - might not know about for improving sports performance: vision therapy.
Several authors have reported importance of visual skills (or sports vision) for sport performance
Visual skills of elite Brazilian soccer players
by: Marcello Alves1, Frank Spaniol & Oscar Erichsen European Journal of Sports Science (0/0/0000)
In conclusion, the present study reports that the visual skills of more developed and experienced elite soccer players (U20 and main squad) are greater than the visual skills of younger and less experienced elite soccer players (U15 and U17).
Considering that these athletes never received specific visual tracking training implies that elite soccer training in itself might be responsible for the development of visual tracking skill.
