BMF’s new breakthrough in optometry: official unveiling of NERCO-BMF Joint Lab for Micro/Nano 3D Printing of Optical Lenses


The 2018 International Forum on Precision Digital Manufacturing and the Future of Vision Science and Optometry was held in China World Summit Wing, Beijing on April 7, 2018. During the forum, team led by Professor Wang Ningli, Member of Academia Ophthalmologica Internationalis and the Director of National Research Center for Ophthalmology (NERCO) collaborated with BMF Material, OnShape Inc. and other globally renowned enterprises, together with a group of world’s top experts in optical lens design and manufacturing, to exchange insights on intrinsic problems in traditional optical lenses and optometric services, and proposed the concept of “New Personalized, High-resolution Optical Lenses”. In-depth partnership has been built for research and development of high-resolution, customized and low-cost production of optical lenses, to meet prescription needs of teenagers, adults and elderly people with refractive errors.

The Forum

Against this background and supported by a number of experts, media and doctors of optometry and ophthalmology, the 2018 International Forum on Precision Digital Manufacturing and the Future of Vision Science and Optometry was successfully held in the China World Summit Wing, Beijing. Within a day’s forum, more than a hundred leaders, optometrists and ophthalmologists from the US, Europe and all over China attended the event and exchanged their points of view.

Nicholas Xuanlai Fang, BMF’s co-founder and Chief Scientist, as well as tenured professor of Mechanical Engineering at MIT, was the Chair of the forum.

During the forum, Professor Wang Ningli, Member of Academia Ophthalmologica Internationalis and the Director of National Engineering Research Center for Ophthalmology (NERCO), explained that traditional refraction test can only adjust the lens in 0.25 diopter increments, and the reason lies in: 1.limitation in traditional lens processing; 2. human eyes have a certain level of accommodation; 3. eyeglass suppliers care about the cost; 4. limitation of lens blank stock and inventory space; 5. workload of the optometrists.

In recent years, the manufacturing industry has witnessed rapid development of 3D printing technology, achieving resolution and micro/nano scale that traditional manufacturing simply cannot be on par with. Yet, attempts to print optical lenses are still very limited. In this regard, BMF has made the first stride, and managed to fabricate optical lenses that meet resolution and other demanding requirements.

To witness this technological breakthrough in China’s eyeglass industry, a group of experts and government officials attended the groundbreaking ceremony of NERCO-BMF Joint Lab for Micro/nano 3D printing of Optical Lenses during the forum. Presented were Huang Zhigang, Vice President of Beijing Tongren Hospital; Professor Wang Ningli, Director of National Engineering Research Center for Ophthalmology (NERCO); Jin Xiaotao, former Deputy Director of National Health Commission of People’s Republic of China; Cao Guoying, Deputy Director General of Department of High-tech Development and Industrialization, Ministry of Science and Technology of the People’s Republic of China; Wu Peixin, Deputy Director General of Department of Science, Technology and Education, National Health Commission of the People’s Republic of China; Zheng Huanmin, Deputy Director and Member of Party Leadership Group of Beijing Municipal Science & Technology Commission; Pan Suyan, Deputy Director of Beijing Municipal Administration of Hospitals; and Sheng Licheng, Working Committee Member and Deputy Director of the Management Committee at Beijing Economic-Technological Development Area.

Groundbreaking Ceremony of NERCO-BMF Joint Lab

Dr. He Xiaoning, CEO of BMF Material, expressed in his speech the aspiration to achieve application of precision optics and 3D printing in medical industry through this cooperative project. The ambition is to realize accurate optometry, precision manufacturing and finally establish a lens design system catering to the needs in China. Collaboration between BMF and NERCO aims at a lens dispensing system of higher efficiency and accuracy, by marrying precision manufacturing of 3D printing with optometry and ophthalmology. In this way, innovation ability and effectiveness in China’s ophthalmology can be greatly enhanced, to meet more needs of the public.

Forum attendees not only had in-depth discussion on technological problems, but also experienced the dispensing of 3D printed lenses. Sample lenses in 0.05 diopter increments- what many optometry professional care much about- were also presented on site. A temporary refraction test display was also designed for the audience to observe high-accuracy optometry in close distance.

When the forum concept “New Personalized, High-resolution Optical Lenses” was raised, it was discussed heatedly among the press, and later covered by many professional media, including the Evening News of China Central TV, Beijing TV, Xinhua Net, International Ophthalmology Times, Focus, etc.


In the future, precision manufacturing of 3D printing will be increasingly applied in optometry and ophthalmology. Let us wait and see.
