As another example, if we had a sphere power of 2.00, a cylinder of -1.50, an axis of 130 degrees, and an add of 1.50. We would follow the same steps as above. Simply put, we would add the sphere power of 2.00 to the add of 1.50, resulting in plus 3.50. The final prescription reading for these reading glasses would be plus 3.50, minus 1.50, at 130.

In the question, r = 8/2 = 4 m and h = 7 m ...Against-the-rule astigmatism means that the strongest axis is the horizontal axis (180 degrees) in plus cylinder which is the same as 90 degrees minus cylinder. Example: Is the following prescription with-the-rule or against-the-rule. +1.00 +2.00 @90. Answer: With-the-rule, because the cylinder is positive and at 90 degrees.
