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.

Rolf Substance is the 3D-printed, plant-based collection from the Austrian eyewear house Rolf. The frames are printed from castor beans. The castor plant grows quickly and thrives in dry areas; it needs hardly any water and does not compete with food crops. The frames are flexible and hypoallergenic, and Rolf's FlexLock hinge is printed as part of the frame, so there are no screws and no metal.
Visionary Optics is an Authorized Retailer of Rolf Substance in New York. Styles in stock can be tried on at our New York stores in the Upper East Side, Chelsea and Carroll Gardens, Brooklyn, and we ship nationwide.
Substance is a line of Rolf eyewear, whose main collection is made from wood and stone.
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. Three parts and two rubber rings. 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. Rolf describes the additive printing process as production that leaves hardly any waste.
The result is eyewear that is light, kind 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 printed in, so the whole frame is three parts and two rubber rings. The result is sustainable eyewear without sacrificing engineering or aesthetics.
