Three new papers have presented further evidence for SightGlass Vision’s Diffusion Optics Technology (DOT 0.2) lenses being safe and effective at reducing myopia progression in children. 

Writing in Ophthalmic & Physiological Optics, researchers led by Professor James Wolffsohn, chief scientific officer for the International Myopia Institute and head of the Aston University School of Optometry, concluded the SightGlass Vision mechanism provides a clinically equivalent visual experience to standard single vision lenses across key measures. “Overall, DOT lenses did not compromise reading metrics (speed, critical print size and near visual acuity), maintained normal head posture and contrast sensitivities, and demonstrated excellent high- and low-contrast visual acuities, stereopsis and an acceptable level of haloes.” 

Adding to the 42-month data from the CYPRESS study extension presented in 2023, researchers published further results in BMJ Open Ophthalmology. They found DOT 0.2 spectacle lenses are safe and effective at reducing myopia progression, with additional benefit evident in year four of wear. “These results support the hypothesis that a mild reduction in retinal contrast can slow myopia progression in young children. The unprecedented disruption in participant schooling and lifestyle during the Covid-19 pandemic may have depressed treatment efficacy in part 1.” 

The third paper, Diffusion Optics Technology (DOT): A Myopia Control Spectacle Lens Based on Contrast Theory, by the University of Washington, Seattle’s Professor Jay Neitz and Adjunct Professor Maureen Neitz, explored how this mild reduction in retinal contrast slows axial growth. 

Independently, these open access papers each deepen knowledge of our innovative technology among the global ophthalmology and optometry communities, said Marcella McParland, vice president of clinical, medical and professional affairs for SightGlass Vision. “Collectively, they are providing eyecare professionals with even more confidence in our approach and the impact that DOT lenses can have on children’s lives today and in the future.”
