I grew up inside an optical shop. My mother likes to tell how, as a kid, I would watch eyeglasses being assembled, play with the tools, and draw on the back of service order slips. The family business taught me early what a precise measurement and work done right are worth. I went on to spend more than twenty years as a software engineer, always keeping an eye on the optical world. Optogrid was born where the two meet: digital measurement technology (pupillary distance and fitting heights) built by someone who knows the dispensing counter from the inside.
Online Eyewear Measurement: PD, SH, and Frame Sizing Explained

Online Eyewear Measurement: PD, SH, and Frame Sizing Explained

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”

Optical Measurement Trends: Digital and Remote Solutions

Optical measurement in eyewear is shifting toward non-contact, image-based techniques and integrated digital workflows. One market-research estimate puts the global optical measurement market at $4.6 billion in 2024 (8.7% CAGR), driven by e-commerce eyewear growth and demand for personalized lenses. Photo-based solutions now enable remote PD and segment height measurement for distributed PPE programs and online retailers.
