Some notes on the construction of "zonal aspheric" aphakic spectacle lenses.
Smith and Atchison (1983) give an optical model of a "zonal aspheric" aphakic lens, but note that lenses mass-produced to this design philosophy do not show similar optical properties to the model. This paper offers an explanation for this discrepancy, supported by lens measurements.
