WebFeb 27, 2024 · If an eyeglass prescription includes cylinder power, it also needs to include an axis value, which follows the cylinder power. The axis is defined with a number from 1 to 180. The number 90 corresponds to the vertical meridian of the eye. The number 180 corresponds to the horizontal meridian of the eye. The axis is the lens meridian that is 90 ... WebThe latter lens has its back vertex a distance x behind the first lens, thus the two back vertex focal lengths are related by fxV'=fV'-x. Taking the reciprocal of this equation we obtain FxV'=FV'/(1-xFV'). where FxV'=1/fxV' and FV'=1/fV' are the back vertex powers of the two lenses. For astigmatic lenses, this must be applied to each meridian ...
