Collecting real measured fitting heights alongside AI estimates, to build an actual calibration model once there's enough data.
Search your live catalog for the exact frame being tested.
A clear, front-facing photo of the person being tested, looking straight at the camera with even lighting. No card or reference object needed — calibration comes from the iris itself.
Fit the actual frame on the person and measure with your usual tool. This is the ground truth every AI reading gets compared against — enter exactly what you measured.
Generates several independent AI try-on composites of this exact frame on this photo. In each one, locates the lens's top edge, bottom edge, and the pupil, and expresses the pupil's position as a percentage of that specific lens's real height — which mathematically guarantees the result can never exceed the lens itself, regardless of what the AI generates. Averages across samples, discarding statistical outliers first. Requires a frame with lens height data selected in step 1, and a photo uploaded in step 2.
Saves the frame, real measured height, and every individual AI reading together.
