Visual performance with aspheric rigid contact lenses
Single vision aspheric contact lens designs may be able to enhance visual performance by controlling spherical aberration. In this study, we have compared the visual performance provided by two front surface aspheric rigid contact lenses with that of a spherical rigid contact lens and spectacle correction. These 4 corrections were worn by ten subjects while visual acuity was determined as a function of aperture size. The possibility that front surface aspheric lens designs may enhance visual performance was confirmed, although individual subjects varied significantly in this visual response. Contributions to the visual performance, other than contact lens surface shape, may include lens position and stability.
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.
