A complete prescription eyeglasses fitting involves six sequential steps: reading the Rx correctly, taking accurate PD and segment height measurements, selecting a frame that fits the face and accommodates the prescription, choosing the appropriate lens material, making professional frame adjustments (vertex distance, pantoscopic tilt, temple bend), and verifying optical center alignment before dispensing.

Short answer: Accurate online eyewear fitting depends on three measurements: pupillary distance (PD), segment height (SH), and frame dimensions. PD errors as small as 1mm can cause prismatic distortion in higher prescriptions; SH errors of 2-3mm in progressive lenses routinely cause non-adaptation. This guide explains each measurement, the tolerances that matter clinically, and where digitalContinue reading “Online Eyewear Measurement: PD, SH, and Frame Sizing Explained”
