A METHOD FOR ASSESSING AN OPTICAL FEATURE OF AN OPHTHALMIC LENS DESIGN

摘要

A method of assessing at least a selected optical feature of an ophthalmic lens design over a prescription and optionally design particularity domain comprising the steps of:
a) selecting a prescription and optionally design particularity parameter set comprising a plurality of prescription parameters in the list consisting of spherical power (SPH), cylindrical power (CYL), cylinder axis (AXE), addition power (ADD) and selecting a prescription and optionally design particularity range for each selected prescription and optionally design particularity parameter so as to define the prescription and optionally design particularity domain;
b) meshing the prescription and optionally design particularity domain so as to provide a plurality of meshing coordinates;
c) providing an assessment criterion for the selected optical feature of the ophthalmic lens design;
d) calculating the assessment criterion value for each meshing coordinate of step b);
e) providing a sensory representation of the assessment criterion values over the prescription and optionally design particularity domain. A method for calculating or optimizing an ophthalmic lens design comprising the use of preceding method.
