Effect of Surfaced Prism on Spectacle Lens Power

Atchison, David A. (1984) Effect of Surfaced Prism on Spectacle Lens Power. Australian Journal of Optometry, 67(1), pp. 19-22.

Abstract

When prism is surfaced to a spectacle lens, the resulting back vertex power at the centration point is different from that predicted by Gaussian theory. This results from oblique incidence of light at one or both surfaces. Formulae are presented which help calculate the back surface power required to be surfaced in order to provide the correct back vertex power.

Citation countsare 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.
