A system and method for determining the measurements needed to correctly fabricate prescription eyewear for an individual who is purchasing the eyewear. The individual is provided with an initial set of frames. The initial set of frames is fitted to the requirements of the individual to obtain a fitted frame. An eye exam is also conducted to obtain a proper lens prescription for the fitted frames. The individual is imaged while the fitted frames are being worn. This creates reference images. At some point, the individual may select a subsequent set of frames. Once the subsequent set of frames is selected, a retailer recalls the reference images and obtains fitting measurements from the reference images. The online retailer can also recall the lens prescription for the initial fitted frames. Utilizing the fitting measurements, the retailer can custom fit the subsequent set of frames.
