Calculation of Extra Curve of Negative Lenticular Spectacle Lenses

Atchison, David A. (1985) Calculation of Extra Curve of Negative Lenticular Spectacle Lenses. Australian Journal of Optometry, 68(2), pp. 54-57.


Lenticular designs are useful for high negative spectacle prescriptions. This paper presents an accurate method for determining the power of the extra curve to be surfaced on the back surfaces of a negative lenticular spectacle lens in order to obtain the required edge thickness. Data required are the front surface power, back surface power, refractive index, centre thickness, full diameter and aperture diameter.

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.
