Abstract
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.
