Mastroianni
The Lunetterie Générale - Mastroianni features a bold rectangular silhouette handcrafted in Japan from premium Japanese acetate. Born from the Montreal atelier founded in 2018 by Julien Couture—where French refinement meets American boldness through a cinephile's eye for mid-century aesthetics and classic cinema—this design features an 8mm thick acetate front and temples with anti-slip grip, combining durability with everyday comfort. Finished with gold and palladium-plated hardware, custom 7-barrel riveted hinges, and signature engraved wire cores, the Mastroianni delivers timeless craftsmanship and refined sophistication. Includes Lunetterie Générale box, case, and cleaning cloth.

Pupil Distance
One last step before checkout
Pupil distance (PD) is the distance in millimeters between the centers of your pupils. It's used to align the optical center of your lenses with your eyes. Most adults have a PD between 54–74 mm. You can find it on your prescription or ask your eye doctor.
Measure Your PD
We recommend using the EyeMeasure app for accurate results
Use your iPhone's TrueDepth camera to measure your pupil distance in seconds. It's the same technology used by opticians.
