Athletes’ performance is largely dependent on their visual acuity and contrast sensitivity, which affect their capacity to absorb visual information and respond quickly in dynamic situations. Gaining an understanding of these visual characteristics helps improve training regimens and equipment, which will improve sports performance.⁽¹⁾ Using data from several studies, this article explores the importance of these visual elements and how they relate to athletic performance.

Visual Skills in Sports

Visual abilities allow athletes to efficiently acquire and interpret information about their surroundings. These talents are divided into two categories: “hardware” (basic visual functions) and “software” (cognitive visual processing), with the latter separating professional athletes from beginners. According to studies, visual abilities may be trained and considerably increase athletic performance. Training might include activities to improve response quickness, visual memory, and the capacity to swiftly change attention between near and remote objects.⁽²⁾

The Role of Visual Acuity

Visual acuity, or clarity of vision, is required for monitoring fast-moving objects and performing precise motions. Repeatability in clinical or laboratory settings requires accurate assessment of these properties. Athletes frequently have better visual acuity than non-athletes, which leads to improved performance in sports that require rapid and precise visual evaluations. Dynamic visual acuity, or the capacity to maintain crisp vision while in motion, is particularly critical in fast-paced sports, considerably influencing performance.⁽³⁾

Contrast Sensitivity and Sports Performance

Contrast sensitivity, or the capacity to differentiate objects from their backgrounds, is critical for recognising small changes in the environment. A higher contrast sensitivity enables athletes to adapt to changes more effectively. Research on sport-tinted contact lenses has revealed increases in contrast sensitivity at specific spatial frequencies, while the therapeutic importance of this enhancement is still debated.⁽²⁾ Even little increases in contrast sensitivity can give a competitive advantage by boosting awareness and reactivity to environmental changes.⁽⁴⁾

Training and Technology

Standardised visual training approaches are required to optimise sports performance. Targeted training can assist increase visual abilities, which can lead to better on-field performance. Protocols should aim to improve fundamental visual functioning as well as cognitive visual processing capacities. Including sports visual aids, such as tailored contact lenses, may offer practical benefits. Despite a little improvement in contrast sensitivity, the overall effect of sport-tinted contact lenses on performance is yet unknown. These lenses can increase comfort and reduce glare, while indirectly improving visual performance.⁽²⁾

Conclusion

Sports performance is heavily reliant on visual acuity and contrast sensitivity, which affect how players perceive and respond to their surroundings. An athlete can perform much better if they have improved their visual abilities via training and technical support.⁽¹⁾ More research is needed to fully understand the benefits of sports vision training and standardise dynamic visual acuity testing. Integrating efficient training techniques and technical tools will be crucial for maximising visual performance as sports vision develops.
