Companies Present Enhanced Lenses, Key Trials Results and Case Reviews in Collaboration with Top Chinese Eye Care Professionals

SightGlass Vision will share its innovative myopia control spectacle lens technology at the International Congress of Ophthalmology and Optometry China (COOC), in partnership with Nikon Lenswear. The conference takes place in Shanghai from April 14-16, 2023, attracting the country’s most prominent eye care clinicians, researchers, and educators.


Spectacle lenses with SightGlass Vision™ Diffusion Optics Technology™ use thousands of micro-dots to softly scatter light to reduce contrast on the retina, a unique mechanism of action to control myopia progression in children. Over the last 18 months, this patent-protected technology with clinically proven efficacy[1],[2],[3] made its commercial debut in several markets, including China. The company operates as a joint venture of CooperCompanies and EssilorLuxottica.


During COOC, SightGlass Vision and Nikon Lenswear will demonstrate the latest lens iteration, featuring enhanced aesthetics that make the micro-dots less visible during everyday wear. In addition, Marcella McParland and Lucill Wang from the SightGlass Vision Clinical, Medical and Professional Affairs team will present side by side with several ophthalmology key opinion leaders, including Dr. Peter Chen from Shanghai ENT and Dr. Liu Longqian from West China Center of Medical Sciences of Sichuan University, to present multiple case reviews and explain results from its multi-year CYPRESS clinical trial. The company has also begun a separate clinical trial in China.


“Since our launch with Nikon in China several months ago, momentum has continued to grow,” said Andrew Sedgwick, CEO of SightGlass Vision. “No other country has the depth of understanding and awareness of myopia’s impact on society as China, nor the experience of its clinical community with the disease. Our introduction of new, evidence-based Diffusion Optics Technology™ to help reach an even larger segment of children has been widely embraced—something we expect to see first-hand at COOC.”


The last several decades have seen a steady rise in the prevalence of myopia worldwide, notably under the effect of lifestyle changes. Today affecting 2.6 billion people globally, it is estimated that nearly five billion people—half the world’s population—will be myopic by 2050.[4] Uncorrected myopia is the leading cause of visual impairment in children. Over time, its progression may contribute to an increased risk of developing permanent vision impairment, including macular degeneration, retinal detachment, cataract and glaucoma, and blindness associated with high myopia[5].


In addition to China, spectacle lenses with Diffusion Optics Technology are currently available in the Netherlands and Israel, as well as through preliminary market trials in other countries. For more information, visit
