According to a recent study conducted by the University of Georgia, athletes can improve their visual range by incorporating fruits and vegetables rich in lutein and zeaxanthin into their diet. These natural compounds accumulate as macular pigments in the retina, significantly enhancing functional vision and the ability to handle exposure to blue light, which can positively impact sports performance. However, individual absorption rates may lead to varying effects among athletes.
Visual range plays a crucial role in the performance of top athletes across various sports.
Nutrition is a fundamental aspect of any elite athlete’s training program. Now, a new study from the University of Georgia suggests that introducing colorful fruits and vegetables to athletes’ diets could enhance their visual range.
Published in the journal Exercise and Sport Sciences Reviews, this research investigates how specific plant compounds known as macular pigments, which accumulate in the retina, contribute to improved eye health and functional vision.
Previous research by UGA scientists Billy R. Hammond and Lisa Renzi-Hammond revealed that consuming foods rich in lutein and zeaxanthin, such as dark leafy greens, yellow, and orange vegetables, has benefits for eye and brain health.
Lead author Jack Harth, a doctoral candidate in UGA’s College of Public Health, emphasized the functional advantages of macular lutein and zeaxanthin. In this study, the researchers focus on their potential to enhance far-distance vision or visual range, a critical asset for top athletes in virtually any sport.
The decline in clarity and increased fuzziness of distant objects are partly attributed to the effects of blue light.
Harth explained how center fielders, for example, face challenges tracking a ball against a bright blue sky or a gray background on cloudy days, as atmospheric interference affects the path of light. Although many athletes already utilize measures like eye black or blue blocker sunglasses to reduce blue light’s impact, Harth highlights that incorporating lutein and zeaxanthin-rich foods into the diet can enhance the eye’s natural ability to handle blue light exposure.
When lutein and zeaxanthin are absorbed, they accumulate as yellow pigments in the retina, acting as a filter to block blue light from entering the eye.
Previous studies in the 1980s examined the visual range ability of pilots, while Hammond and Renzi-Hammond conducted more recent research on how macular pigment density, or the amount of yellow pigment in the retina, correlates with various measures of eye health and functional vision tests.
Billy R. Hammond, a professor of psychology in the Behavior and Brain Sciences Program at UGA’s Franklin College of Arts and Sciences, emphasized the positive impact of increased lutein and zeaxanthin in the retina and brain, leading to reduced glare disability and discomfort, improved chromatic contrast and visual-motor reaction time, and enhanced executive functions like problem-solving and memory – all crucial abilities for athletes.
The paper brings the understanding of the links between macular pigment and functional vision up to date and examines the potential for optimizing athletic performance.
Harth expressed the desire to progress beyond laboratory tests and measure individuals’ ability to perceive contrast over distance in real outdoor environments with blue haze.
However, Harth cautions that individual differences may affect how the body absorbs and utilizes lutein and zeaxanthin, and improvements, if observed, might take time to manifest.
Nonetheless, the overall health benefits of consuming more lutein and zeaxanthin are well-supported, providing ample reason to add more colorful foods to one’s diet, as concluded by the authors.
In conclusion, the study’s findings offer a clear application for athletes seeking to enhance their visual range by incorporating lutein and zeaxanthin-rich foods into their daily nutrition.

Frequently Asked Questions (FAQs) about visual-range-improvement
What does the University of Georgia study suggest regarding athletes’ visual range improvement?
The University of Georgia study suggests that athletes’ visual range can be improved by consuming fruits and vegetables rich in lutein and zeaxanthin. These plant compounds accumulate as macular pigments in the retina, enhancing functional vision and the ability to handle exposure to blue light, ultimately aiding athletes’ performance in sports.
Why is visual range important for top athletes in sports?
Visual range is critical for top athletes in almost any sport because it determines how well a person can see a target clearly over a distance. For athletes like center fielders, the ability to track a ball against bright blue skies or other backgrounds is crucial for their performance.
How do lutein and zeaxanthin-rich foods improve athletes’ eye health and functional vision?
When athletes consume foods high in lutein and zeaxanthin, these compounds accumulate as yellow pigments in the retina. Acting as a filter, they prevent blue light from entering the eye, thus improving the eye’s natural ability to handle exposure to blue light. This leads to reduced glare disability and discomfort, improved contrast perception, visual-motor reaction time, and enhanced cognitive functions like problem-solving and memory, all of which are essential for athletes.
Are there individual differences in the absorption of lutein and zeaxanthin?
Yes, individual absorption rates may vary, meaning that not everyone may experience the same level of improvement in visual range after consuming lutein and zeaxanthin-rich foods. Some individuals might notice improvements more quickly, while for others, it may take more time or not be as pronounced.
Can consuming more lutein and zeaxanthin-rich foods have overall health benefits beyond visual range improvement?
Yes, apart from enhancing visual range, consuming more lutein and zeaxanthin-rich foods offers several other health benefits, including improved eye and brain health. These plant compounds have been associated with reduced glare disability and discomfort, enhanced contrast perception, and better cognitive functions like problem-solving and memory.
Where was the study published, and what is its title?
The study was published in the journal “Exercise and Sport Sciences Reviews.” The title of the paper is “A Dietary Strategy for Optimizing the Visual Range of Athletes.”
How does blue light exposure affect athletes’ vision?
Blue light exposure can make distant objects harder to see and appear fuzzy due to atmospheric interference. This interference occurs when objects are viewed against a bright blue sky or gray background on cloudy days, affecting the path of light and making the target less clear.
Is the improvement in visual range applicable to athletes in all sports?
Yes, the improvement in visual range through the consumption of lutein and zeaxanthin-rich foods is applicable to athletes in virtually all sports. Visual range is critical for various athletic activities, whether it’s tracking a ball in baseball, soccer, or other sports that require precise vision over a distance.
Can the study’s findings be applied to optimize athletic performance?
Yes, the study’s findings offer a clear application for athletes seeking to enhance their visual range and overall performance. By incorporating lutein and zeaxanthin-rich foods into their diet, athletes can potentially improve their functional vision and gain an edge in their respective sports.
