HACK: Stroboscopic glasses. In highspeed games, players have to make instantaneous decisions in reaction to only a glimpse of the action. Athletes learn to function with less information— resulting in improved reaction time, visual acuity and sense of timing. In a two-week study using professional hockey players, stroboscopic training showed an 18% improvement over a control group in specific on-ice skill tests.
New glasses, using similar techniques, will be developed to increase other visual abilities, including peripheral vision and multiple object tracking.
That improvement for on-ice skills for professional players is huge.
