VertexLensCalc is a free online calculator that converts eyeglass (spectacle) prescriptions to contact lens prescriptions using the standard clinical vertex distance formula (ISO 8980-1 and ANSI Z80.1). It handles sphere, cylinder, axis, astigmatism (toric lenses), and advanced parameters like pantoscopic tilt and face form angle. Results are provided instantly with no sign-up required, though it advises verification with an eye care professional.
