Unravelling contact lens specifications

Efron, Nathan (1980) Unravelling contact lens specifications. Australian Journal of Optometry, 63(6), pp. 273-279.


Contact lens practitioners often rely on specifications supplied by manufacturers for information on new lens materials and new lens designs. Comparison of different contact lenses on the basis of this information is made difficult by the use of non-standard test procedures and a lack of consistency in the presentation of data. In this paper commonly used parameters are explained and their relative importance is discussed. It is suggested that independent reports provide the best method of comparison.

Citation counts are sourced monthly from Scopus and Web of Science® 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 the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
