Progressive Powered Lenses: the Minkwitz Theorem
@article{Sheedy2005ProgressivePL, title={Progressive Powered Lenses: the Minkwitz Theorem}, author={James E Sheedy and Charles S. Campbell and Ewen King-Smith and J. Hayes}, journal={Optometry and Vision Science}, year={2005}, volume={82}, pages={916-922} }
PURPOSE
The Minkwitz theorem, which can be proven to apply to the immediate surface surrounding a line of umbilics, states that astigmatism perpendicular to the line changes twice as quickly as the rate of change of power along the line. [...] Key Method Lenses were measured with a Rotlex Class Plus lens analyzer.
RESULTS
Zone widths in the central region of the Tact lenses exceeded those predicted by the Minkwitz theorem. Above and below this region, zone widths were narrower than predicted. When averaged…Expand Abstract
