Varifocal fitting measurement — test tool

Prototype only, for internal validation of the technique.

Two different things live here, don't mix them up: PD is a genuine measurement of the face alone and works the same regardless of whether the customer has the frame. Fitting height is only a real measurement when there's an actual frame on an actual face — a 2D photo has no depth information, so for online-only customers who've never touched the frame, it can only ever be a standard estimate for that lens design, not a personalized number. Every result here — measured or estimated — should be confirmed by a GOC-registered optometrist before it reaches a real order.

1. Choose a frame (optional)

Search your live catalog to tag this test with the real product being measured.

2. Does the customer have the physical frame?

This determines what fitting height can honestly be: a real measurement, or a standard estimate.

3. Upload a photo

A clear, front-facing photo, looking straight at the camera with even lighting. No card or reference object needed — calibration now comes from the iris itself.
