Optogrid is a web-based measurement platform that allows opticians and eyewear retailers to accurately extract key optical parameters such as pupillary distance (PD), dual PD, and segment height from customer photos. Using a known reference object (like a frame or credit card) to calibrate scale, Optogrid enables precise remote measurements, streamlining the process of fitting prescription lenses for both in-store and online eyewear orders. It helps reduce remakes, improve accuracy, and make remote eyewear sales more practical.
