Description
PUPILLARY DISTANCE PD+ instantly measures pupillary distance (PD) by capturing & processing a single, hi-res facial photo. Measurement accuracy is guaranteed to be the highest achievable by the capability of your device's camera system. Far and near PD's -- binocular & monocular -- are always available at no cost. FITTING HEIGHT PD+ instantly measures Fitting Heights for the frames you currently have on. Accurate fitting height and PD measurements are needed to ensure that lenses being made for your frames are properly centered on your eyes to achieve optimal viewing clarity. In addition, Fitting Heights are used to position segments for fitting multifocal lenses. Please note: Fitting Height is currently only supported on devices equipped with the TrueDepth or LIDAR camera systems (e.g., iPhone X and later non-SE models). CALCULATORS - Rx Transposition - Vertex Adjustment - Crossed Cylinders (over-refraction) - Keratometry Conversion - Visual Acuity Scale - Estimated visual acuity - Minimum Blank Size (MBS) - Simple Magnifier and Spectacle Magnifications
