Assessment of toroidal surfaces by the measurement of curvature in three fixed meridians.

C W Fowler1.   

Abstract

A method is described where the surface curvatures and axis orientation of a toroidal surface can be determined by measuring the lens in three fixed orientations. This method also has possible applications in the measurement of progressive addition lenses.
