Vision in competition pistol shooters: effects of distance defocus on performance
We examined the effects of adding positive spherical lenses to distance spectacle prescriptions on the pistol shooting performance of nine experienced shooters. Shot groupings were significantly smaller horizontally when shooters wore a +0.50D addition and significantly smaller vertically when shooters wore a +0.75D addition to their distance spectacle correction. Performance became significantly worse with spectacle additions of +2.00D and +4.00D. We discuss possible mechanisms for the improvement in performance obtained by using low plus additions for presbyopic and non-presbyopic pistol shooters.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloadsdisplays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
