Reaction times in a complex task by presbyopic observers with spectacle and contact lens corrections
Brown, Brian, Collins, Michael J., & Bowman, Kenneth J. (1988) Reaction times in a complex task by presbyopic observers with spectacle and contact lens corrections. Cinical and Experimental Optometry, 71(3), pp. 94-99.
Reaction times were measured in a complex three distance task for presbyopic subjects wearing multifocal spectacle corrections or bifocal contact lens corrections; the same taks was performed by young control subjects with no correction and further groups of young control subjects wearing hard or soft contact lenses. The targets could be discriminated only if subjects were looking directly at the displays. The reaction times were at least for targets presented at the intermediate distance, and increased for near and distance targets. Subjects wearing spectacle corrections gave better performance on the whole than those wearing the contact lens corrections, but there were no significant differences in reaction times between the two spectacle corrections used or between the six contact lens corrections used. Neither of the presbyopic groups performed as well as the young control group.
Impact and interest:
Citation counts are sourced monthly from and 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 downloads displays 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.
