Contact Lens Vertexing Chart - Web back vertex distance calculator. Web web the contact lens vertex calculator helps eye care professionals determine the correct contact lens power to compensate for the change in prescription caused by the vertex distance. To use a vertex conversion chart, the sphere number on the glasses prescription is looked up in the middle column, and if there is a ‘minus sign’ in front of it, the conversion is on the left, if there is a ‘plus sign’ in front of it, the conversion. Enter the initial and final vertex distances. On the chart, note that the middle columns (yellow) refer to the absolute spectacle lens power in diopters. Since the final vertex distance for a contact lens is zero, this value is set to 0 by default.
