Thanks for showing the complexity of the Phoropter. I know that the "spherical" measurement is easy. I never realized how much time was taken to measure the "Cylinder" of the eye's refractive status. It is of interest that her visual acuity (with no lens) was not checked. Thanks!
Also, you increased cyl by 0.50 OS, so you should have automatically reduced sphere by 0.25. Is this a tech being trained on JCC?

JCC is not a prism.
