    Aspheric and high powered lenses help

    Hi wondering if anyone could help on the following:
    Does their appear to be any connection between lens centre thickness and NVEE?
    What is the significance of this value when you are dispensing high-plus lenses to a patient to be used for reading and near work?
    Does there appear to be any connection between lens centre thickness and results?
    What is the significance of these findings when you are dispensing high plus multi-focal lenses to a patient?

    Darryl gave a nice example of NVEE for a student some time back:

    I believe all you questions would be answered from this post.

    1st Mac Compatible Tracer Software
    1st Linux Compatible Tracer Software

    *Dave at OptiVision has a web based tracer integration package that's awesome.
