The Use Of WJ Prosoft Contact Lenses For Outdoor Sports Vision Enhancement.

Purpose: This study was conducted at the Ferris State University outdoor softball facility to evaluate the performance of six FSU softball players wearing Wesley Jessen Prosoft contact lenses. Methods: The study was done in two sessions on the same day. During the first session, half the players were wearing the Prosoft lenses and the other half were wearing their clear lenses. During the second session, the players initially wearing the Prosoft lenses wore their clear lenses and the players initially wearing their clear lenses wore the Prosoft lenses. A pitching machine was used to deliver an optical yellow softball to the batters on the softball field. Two observers, who did not know which lenses the subjects were wearing in a given session, evaluated the players' hitting performance during each session. A comparision between the "clear lens (control) group" and the "Prosoft lens (experimental) group" was conducted using a twotailed, paired t test. Results: A slight improvement in performance was noted for five of the six players while wearing the Prosoft lenses versus their clear lenses, but no overall, statistically significant difference was noted between the two groups. Conclusion: Enhanced performance while wearing the Prosoft lens for softball competition was not demonstrated in this study.
