Revolution in the eyewear industry: Yuniku

Yuniku, the world’s first 3D-tailored eyewear to introduce vision-centric design — and an open digital platform that allows any eyewear brand to do likewise.

Conventional eyewear design begins with the frame. Once a customer in an optician’s shop has chosen the frame that they like, the optician selects and places the optical lenses that fit the customer’s visual needs. But placing lenses into a chosen frame can negatively impact lens alignment, resulting in less-than-ideal lens performance. So how do you build eyewear which actually gives the wearer optimal visual experience?

Yuniku uses 3D scanning, parametric design automation and 3D Printing to design the frame of a customer’s choice around the optical lenses chosen by the optician. “Since the position of the lenses are preserved, this concept ensures the ideal orientation of the lenses in your final glasses, in turn ensuring the best visual performance,” says Felix España, Global NewMedia Manager at HOYA Vision Care. Besides, 3D Printing allows for complete customization of the frames for the customer’s anatomical features as well as aesthetic preferences.

Hoet Design Studio, the design partner for the base collection of eyewear frames to be used by Yuniku, is already seasoned in 3D-printed eyewear. For Bieke Hoet, Yuniku is an opportunity to take high-performance eyewear from a luxury concept into a normal eye care professional’s reality. “As an eyewear designer,” Bieke says, “I’m already familiar with how 3D Printing can revolutionize this industry. And now with Yuniku, we can share this potential with the world.”

“When we started working with Materialise in 2014, for the HOYA Vision Simulator and EyeGenius, the collaboration led us to start thinking about bigger breakthroughs that our combined knowledge could trigger,” – recalls Felix.


Co-Creating a Fully Digital Supply Chain

“What we were looking for was not only a manufacturing partner but an all-round collaborator at every stage.”

To start, in a co-creation, the Materialise Design & Engineering services began adapting their 3D scanning technology to gather a highly-detailed digital 3D scan of the customer’s facial features and thereby meet the needs of the HOYA NewMedia team. 

Meanwhile, the Materialise R&D team worked with HOYA to develop the Yuniku software. The software allows the eye care professional to take the customer on a journey. After the scan is taken, advanced software designed by HOYA uses facial and visual data to determine the ideal position of the lenses in relation to the eyes and communicates this with Materialise’s software, which in turn tailors the frame around the lenses according to the wearer’s unique facial characteristics. Frame design, color and finish can all be adjusted to match the customer’s individual style, guided by the expertise of the eye care professional. The integrated software solutions work in the background to ensure that both ideal lens positioning and fit are preserved. When the perfect 3D-tailored glasses are designed, a back-end ordering system sends HOYA the data required for lens production, and Materialise, the data needed for manufacturing the frames.

At Materialise, the frames are manufactured using Laser Sintering technology dedicated for eyewear, tuned to highly precise parameters using the Materialise Control Platform to access nuanced hardware settings. Finally, the frames undergo the multi-stage post-production treatment of Materialise Luxura. Every frame that comes out of this manufacturing process is entirely unique, and authenticated to an individual end-user.

“Materialise innovations have a long track record of developing end-to-end solutions to enhance interaction mechanisms between customers and professionals, enabling novel experiences and innovation in product development,” – notes Alireza Parandian, 3D-printed wearables expert at Materialise. “But HOYA Yuniku goes a step further, by introducing an open system that reaches far beyond any single brand.”


A Yuniku Experience, With an Open Platform

Although the experience will undoubtedly feel unique for any lifelong glasses-wearer, the Yuniku platform is an open one which can be implemented across any number of stores with any number of brands. Yuniku has been launched with a base collection designed by Hoet Design Studio, and will eventually grow to include frames from other designers as well.

For glasses-wearers, Yuniku represents a future where lenses and frames work together rather than compromising each other; where their specific optical needs and aesthetic preferences can be met in a single pair of glasses. For eye care professionals, the Yuniku system empowers them to use their knowledge and take their customers on a novel and exciting journey. But for the eyewear industry and for Additive Manufacturing, Yuniku is not only design automation but a launch pad of innovation.
