Substance
The original line. Every frame 3D-printed in a single pass from castor bean bioplastic. Flexible, hypoallergenic, remarkably light. The frame that proves plant-based eyewear can be as refined as anything else in the case.

NYC's Largest Luxury Eyewear Collection
Rolf Substance is what an Austrian eyewear family came up with when they decided to print glasses from a bean. The Substance collection is 3D-printed from a bioplastic made entirely from castor beans, a fast-growing plant that thrives in arid climates, requires no irrigation, and doesn't compete with food crops. The result is eyewear that is flexible, hypoallergenic, remarkably lightweight, and made without screws, metal, or waste.

PRINTED IN AUSTRIA · BORN FROM A BEAN
The original line. Every frame 3D-printed in a single pass from castor bean bioplastic. Flexible, hypoallergenic, remarkably light. The frame that proves plant-based eyewear can be as refined as anything else in the case.
Bolder shapes for optical and sun. Mount frames push the silhouette further with heavier acetate-style profiles and the same 100 percent plant-based construction. Architectural without being heavy.
The newest Substance line. A surface treatment that adds depth and contrast to the printed frame, with subtle color accents on the temples. Aura takes the bioplastic in a more design-forward direction.
Every Substance frame begins as castor bean powder. The beans are ground, mixed with water, and printed layer by layer into a finished frame. No assembly. No screws. No metal. The hinge is printed into the frame itself, in the same pass as everything else.
Castor beans are a fast-growing plant that requires no irrigation and does not compete with food crops. The additive printing process uses only the material the final frame requires, so there is no waste.
The result is eyewear that is lighter than acetate, kinder to sensitive skin, and made from a material that started as a seed in a field.

Rolf Substance is the plant-based 3D-printed collection from Rolf, the Austrian eyewear house founded in 2009 in the Tyrolean Alps. Substance frames are made from a powder derived from castor beans — a fast-growing tropical plant in the Euphorbiaceae family that requires no genetic engineering and doesn't compete with food crops.
Visionary Optics carries the Rolf Substance collection across our three NYC locations. Each frame is 3D-printed with Rolf's signature Flexlock screwless hinge co-printed into the single-piece structure — the result is genuinely sustainable eyewear without sacrificing engineering or aesthetics.
