Choosing glasses is already a photographic act. Customers hold up a frame, photograph themselves in the mirror and send it to a friend before deciding, and they do this without being asked. A branded booth simply formalises behaviour that is happening anyway, and returns an image with the product on the customer's face and the retailer's name around it. At this store count the arithmetic is unusual: even a small pilot implies real volume, and a successful one has thousands of locations to expand into.
