Abstract
Apparatus is described for the measurement of lens power distribution across the surface of a progressive addition spectacle lens. Although the method used is different to that specified in BS 2738-7:1996, the measurements are nevertheless comparable, and are considered sufficiently accurate for making basic comparisons of lens type.
