Neurodynamic Vision Training
Flexible NDVPerformance training options to meet your busy schedule
The same way you train your body to perform better through physical strength and biomechanical techniques, you can now add Eye-Mind-Body reaction speed for improved Confidence, Consistency and Concentration
NDVPerformance Program Benefits
Comprehensive neurodynamic vision education and practical training modules to train your brain to see faster
Despite popular belief, 20/20 vision is not a good predictor of visual performance. Vision performance is dynamic and happens in the blink of an eye (400ms /.4 sec). The brain can be trained to ‘see faster’. Since 80% of all information is visual and 50% of the brain is connected to vision processing, the improved visual function will lead to improved speed and quality of data for the brain to process.
The science is backed by proven results from our elite athletes, coaches, and trainers. We offer training that includes a comprehensive body of scientific evidence to support effectiveness that is widely used by professional sports organizations
