    Again on martin's rules

    I use martin's rules for everything Sv job (above 0.25dp) , I tell the client to raise the head to 0 panto of the frame and dot the lens.

    My colleague use it only for aspheric Sv job and use primary gaze line for spherical lenses.

    It is better him or I?

    I use primary gaze of vision only for oc height of pal's

    You must always balance Martin’s Rule against the impact of abbe when the panto is 8 degrees or more.
