In AXIS, the lens meridian plays an important role. The interesting fact is that if the prescription of eyeglass includes the main cylinder power, it is important to include the axis value along with it so that it follows the power of CYL. The axis depicts the angle between two meridians. The numbers are from 1 to 180 in the axis part of the ...An alternate way to write a spherocylinder prescription, which is equivalent to and equally correct with the “minus cylinder” form, is the “plus cylinder” form. To convert from minus cylinder to plus cylinder form, or visa versa, do the following: 1. Add the sphere and cylinder powers together; this becomes the new sphere power. 2.The cylinder power can be positive or negative. The sign of the cylinder determines whether the prescription is in plus or minus cylinder form. Now the problem is how to relate the sphero-cylinder form (3) to the crossed cylinder form (2).
