I was kind of curious, and suspect a few others will be, what do Nagler's published prescriptions' raytrace look like. One more reason is that no complete raytrace of its patents exist (that I know of), and those partial ones (that I know of) are grossly inaccurate. Even Rutten and Venroij (1st ed.) present the first patented Nagler as having about 1.5mm longitudinal astigmatism in the outer 1/2 field area, while the actual one at 40 deg off is 0.23mm, for little over 2 waves p-v. Gross' "Handbook of Optics" is worse in this respect, etc. Main reason for this inaccuracy is raytracing entire field with a single exit pupil location, giving grossly distorted values (and ray spot plots) for the field points coming to different exit pupil locations. So here are complete, properly raytraced prescriptions, in their actual size, all 10mm f.l. and directly comparable (ExP is exit pupil distance from the eye lens, ACC is needed accommodation in diopters and DIST is rectilinear distortion). Accommodation of 1 diopter corresponds to ocular focus adjustment from infinity (field center) to about 1m distant object.
