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.

What 14,904 Pupillary Distance Measurements Tell Us About Human Faces
Why look at PD at scale? Pupillary distance (PD), the millimetres between the centres of your pupils, is the silent hero behind lens alignment. When PD is off, even a perfect prescription can feel blurry or induce strain. Because Optogrid captures PD remotely, we now have thousands of real-world readings instead of the handful anContinue reading “What 14,904 Pupillary Distance Measurements Tell Us About Human Faces”

Lens Manufacturing Technology: From Blank to Finished Prescription Lens
Short Answer: Ophthalmic lens manufacturing transforms a semi-finished lens blank into a prescription lens through four core stages: surfacing (or freeform generation), polishing, coating, and edging. Material choice (CR-39, polycarbonate, Trivex, or high-index plastic) determines the optical and physical properties of the final lens. Coating technologies (AR, hard coat, hydrophobic, oleophobic, and blue light filter) are applied in layers to improve performance and durability.
Essential Software Solutions for Eyewear Retailers
Short Answer: Eyewear retailers need software across seven categories to operate competitively: inventory management, point-of-sale, CRM, e-commerce, remote PD measurement, data analytics, and virtual try-on. The priority order depends on your business model — brick-and-mortar shops should start with inventory and POS, while online-first retailers need e-commerce and PD measurement tools from day one.
