Following up on our first article, published in Points de Vue in November 2020, we continue our discussion of a new vectorial method for determining the cylinder. This second article compares the techniques used in "traditional" refraction with a new "digital" refraction method for determining the cylinder axis and cylinder power during a refraction examination.
