Ingredients for a Successful Progressive Rx
There may be some debate in our industry about which factors are the most critical in successfully dispensing progressive lenses. Is it the design? β¦base curve? β¦material index?
In my view, itβs perfectly clear: The factors directly controlled by the ECP are still the most important!
Hierarchy of importance:
β’ Most critical: Proper refraction, fitting height & PD measurement
β’ Second most important: Base curve selection, progressive design, corridor length, material index
β’ Nice to have (icing on the cake): Customization, individual wearer parameters
Lens designs have improved far beyond what I ever imagined in the early 1970βs, but one thing hasnβt changed: the ECP is still the most important ingredient in the mix. Technology can never replace a competent and well-informed eyecare professional.
