The Great Frog Prometheus
Created in collaboration with The Great Frog, the Prometheus Optical is a true embodiment of anarchic artistry and Gothic realism. Forged from premium Italian acetate, this square silhouette features Sterling Silver Dagger emblems on the frontal, with up-swept lugs that evoke the imagery of licking flames. Inspired by the dark tales of the Underworld, the faceted profile reflects light beautifully, adding dimension to the design. This handcrafted frame merges over a century of craftsmanship, making it a powerful statement for those who embrace bold, rebellious style. Includes Cutler & Gross case, cleaning cloth, and 1-year manufacturer warranty.

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.
