Sofia Matos, a researcher at the School of Sciences of the University of Minho (ECUM), has been distinguished by the American Academy of Optometry with the prestigious Garland W. Clay Award, recognizing the most impactful scientific article of the year in the field. The award was presented at the Academy 2025 Boston meeting in the United States.
Entitled “Long-term effect of dual-focus contact lenses on myopia progression in children”, the article was published in the journal Optometry and Vision Science and co-authored by nine researchers from the United States, United Kingdom, Singapore, Canada, and Australia, along with the scientific director of CooperVision. The team has been conducting an international clinical study for several years and had already received the same award in 2021 for another publication. “It is an honor to receive this award again, which recognizes our contributions over the last five years,” says Sofia Matos.
The recent research analyzed the impact of dual-focus soft contact lenses (MiSight 1 Day) on myopia progression in children over a six-year period. The results showed a significant and sustained slowdown in myopia progression, as well as in axial eye growth. Children who switched from conventional lenses to treatment lenses after three years also recorded a 71% reduction in eye growth. The effect was maintained throughout the six years and was well tolerated in 90% of cases.
These lenses have been approved by the U.S. Food and Drug Administration (FDA) as the first clinically proven product to slow myopia progression in children aged 8 to 12 at the start of treatment. “The clinical trial underlying this work is a milestone in advancing myopia control in children, highlighting the impact that collaborative research can have on global visual health,” adds Sofia Matos, noting the contribution of the Clinical and Experimental Optometry Research Laboratory (CEORLab) of UMinho’s Department of Physics, in collaboration with international partners.
The Garland W. Clay Award is one of the most prestigious distinctions in the field worldwide. Established in 1978, it recognizes the best articles published in the American Journal of Optometry and Physiological Optics (now Optometry and Vision Science), based on criteria such as originality, clinical relevance, research integrity, and quality of presentation.
