The dispensing maths, tappable

Frame in, Rx in... out comes minimum blank, cut-lens edge thickness, and the index comparison that sells the thinner lens. Grey-field spreadsheet energy, retired.

Frame

Patient PDs (monocular)

The Rx

Sphere and cyl per eye... thickness is computed on the worst meridian (sph + cyl), the honest way.

Right · OD
SPH−4.00
CYL−0.75
Left · OS
SPH−3.75
CYL−0.50

The results

Blank size · worst eye

Index comparison · edge at the cut lens
