Ngoc Minh Refraction Center, formerly Ngoc Minh Optical - TTLENS CORPORATION, is proud to be a member of the TTLENS Group system, specializing in the control of myopia, astigmatism, hyperopia and presbyopia, combined with a showroom of authentic Korean prescription eyewear such as God Of Light, GOL Eyewear, Myung Eyewear, L&M Eyewear and Chemi. With more than 15 years of experience and credibility, we have expanded our branches to major cities including Hanoi, Ho Chi Minh City, Da Nang and Nha Trang.
In Vietnam, many ophthalmology clinics invest heavily in clinical expertise and often treat customers mainly as patients, so they do not yet focus enough on precision technology in lens edging and fitting or on the full service process. Meanwhile, many standalone eyewear showrooms do not have a specialized eye-care team, rely entirely on machines, or focus mainly on fashion eyewear.
In that context, with a philosophy of creativity, vision and innovative thinking, we have built a model that combines clinics, refraction centers, myopia-control services and prescription eyewear under the guiding principle "Brand from the heart". This model brings together the experience of leading eye-care doctors and specialists in Vietnam with modern Korean and American lens edging and fitting technology to deliver convenience, peace of mind and comfort, while ensuring excellence in both professional quality and customer care.
Vision
Eyes are precious gems. We aspire to bring light, clarity and sharp vision to every customer by applying advanced global technologies together with the golden experience of leading vision specialists, narrowing the gap between technology application in Vietnamese medicine and the rest of the world.
Mission
To continuously grow, apply highly accurate advanced technologies, and develop optimal products for eye health and vision care.
Development journey
Ngoc Minh Refraction Center is still operated and controlled by its founding shareholders, who have remained close friends up to the present day.
