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 ... Web– Vertex distance – Pantoscopic tilt – Face-form wrap • Vertex distance can be measured using a distometer or approximated using either a pupilometer or a PD ruler • Pantoscopic tilt should be measured on the wearer from a vertical plane parallel to the face and perpendicular to the line of sight in primary (straight-ahead) gaze
