    I would start with 0.75 cyl. using high is also possible if you think

  3. I never prescribe a stronger cyl in a soft lens than the measured
    spectacle cyl. It just seems wrong to do that (mainly because you end up
    with axes in the residual that are 90 deg off from the patient's
    uncorrected state. So to me the choice is obvious.
