Scientific Posters from SightGlass Vision Explore Efficacy with Contrast Management Across Diverse Populations, Lack of Relationship with Astigmatism
SightGlass Vision is presenting findings from two scientific studies on March 9 at the 2026 Netherlands Contact Lens Congress (NCC) to further reinforce prescriber confidence in its DOT™ spectacle lenses. Both focus on the power of contrast management for slowing myopia progression in children; one explores efficacy across diverse populations and the other investigates its relationship to astigmatism.
“Our contributions to this year’s NCC program add to the substantial body of evidence surrounding our innovative DOT spectacle lenses,” said Andrew Sedgwick, CEO of SightGlass Vision. “More than 1.5 million children have already worn these lenses worldwide, and we are committed to helping eye care professionals understand their immense potential through rigorous clinical science and experience.[1]”
Efficacy of Contrast Management Spectacle Lenses in North American and Chinese Children (Carta F, et al) analyzed 12-month data sets from two long-term, multicenter randomized controlled clinical trials. Despite the diverse participant ethnicity (North America: 75% Caucasian, 20% Black; China: 100% Chinese), both axial length (AL) progression and cycloplegic Spherical Equivalent Refraction (cSER) progression were significantly slower in children who wore DOT lenses compared to the control groups. The study was conducted in partnership with Indiana University.
Relationship Between Contrast Management Spectacle Lenses for Myopia Control and Refractive Astigmatism (Webley D, et al) explored if potential links between peripheral defocus spectacle lenses and increased astigmatism could extend to contrast management.[2] Investigators evaluated right eye refractive data from two long-term, multicenter clinical trials of DOT spectacle lenses in North America and China, noting astigmatism (>0.25DC) at baseline and 12 months. No significant change in astigmatism between the test and control groups infers that practitioners can prescribe DOT lenses with minimal concern of inducing this undesirable effect. The work was conducted with Aston University.
NCC takes place from March 8-9 at the NH Conference Centre Koningshof in Veldhoven, Netherlands, attracting clinicians, researchers, educators, and developers from across the ocular science and eye care spectrum.
DOT lenses are the first myopia management treatment specifically designed to reduce retinal contrast signalling through the incorporation of light scattering elements.[3] Children are spending more time indoors, studying, reading, and playing in modern, artificial environments, which may be linked to accelerated myopia progression.[4][5][6][7][8] The lenses mimic more natural contrast to counteract this.[9],[10] They have made their commercial debut in Canada, China, Israel, Spain, and the U.K. *
