So it makes sense then when a recent vision and eyesight study conducted by Dr. Daniel Laby — the Director of the Sports and Performance Vision Center at the SUNY College of Optometry in New York City — once again confirmed that professional players essentially have superhuman vision levels, with many approaching 20/12. Additionally, it confirmed the accuracy of an autorefractor device that can detect minor focusing issues in players’ eyes, the major finding in the study released last week.
