MiSight® Spectacle Lenses Powered by Diffusion Optics Technology™ Launches in Canada to Slow Myopia Progression
Wednesday, July 2 2025 | 17 h 07 min | News
CooperVision announced the launch of breakthrough MiSight® Spectacle Lenses powered by Diffusion Optics Technology™ for myopia control in Canada.
Diffusion Optics Technology™ uses a unique, patent-protected mechanism to lower contrast signals that can cause myopia progression in children.1 Beginning July 1st, Canadian Eye Care Professionals will be able to prescribe this proven intervention to help slow the progression of myopia in their young patients.±2
The innovative approach is backed by extensive research, including the pivotal CYPRESS clinical trial conducted across 14 sites in North America1 and the ongoing CATHAY clinical trial across 5 sites in China.3 MiSight® Spectacle Lenses slow average myopia progression by up to 75% after 12 months of wear across diverse populations of children.‡1,3
The rigorous, multi-site four-year CYPRESS clinical trial demonstrated that among children wearing MiSight® Spectacle Lenses, 41% of children showed no meaningful progression in refractive error over 24 months.†2
“MiSight® Spectacle Lenses provide another scientifically proven myopia control option alongside our MiSight® 1 day.* We are enthusiastic about bringing this advancement to Eye Care Professionals in Canada, and about the potential it offers for so many children,” said Enrique Contreras, Country Manager for CooperVision Canada.
“We expect the availability of MiSight® Spectacle Lenses to significantly expand myopia control access4 for children in Canada, particularly among younger patients for whom spectacles may be a preferred form of treatment. Adding MiSight® Spectacle Lenses to an Eye Care Professional’s toolbox helps to increase access to evidence-based technologies, especially for younger children, which helps drive towards a shared goal of making myopia management a standard of care,” said Andrew Sedgwick, CEO of SightGlass Vision.
MiSight® Spectacle Lenses provide a positive wearing experience with 93% of children saying they love their MiSight® Spectacle Lenses.│2 Studies also show that MiSight® Spectacle Lenses provide a clinically equivalent visual experience to standard single vision lenses.5-7

* USA Indication: MiSight® 1 Day (omafilcon A) Soft (Hydrophilic) Contact Lenses for daily wear are indicated for the correction of myopic ametropia and for slowing the progression of myopia in children with non-diseased eyes, who at the initiation of treatment are 8-12 years of age and have a refraction of -0.75 to -4.00 diopters (spherical equivalent) with ≤ 0.75 diopters of astigmatism. The lens is to be discarded after each removal. Canadian Indications for Use: MiSight (omafilcon A) Soft Contact Lenses for Myopia Control may reduce the rate of myopia progression in children (6-18) and correct ametropia. Reduction of myopia progression was observed in children with wearing time of 12 hours (8-16 hours) per day, 6.4 days (5-7) per week in a clinical study. Permanent myopia control after lens treatment is discontinued is not supported by clinical studies. MiSight (omafilcon A) Soft Contact Lenses for Myopia Control are indicated for single-use daily disposable wear. When prescribed for daily disposable wear, the lens is to be discarded after each removal.
± Reduction in progression of spherical equivalent refraction and axial length from baseline over 24 months was 47% and 24% on average, respectively (p<0.0041).
‡ Based on a North American patient population aged 6–10 years (least-squared means) and a Chinese patient population aged 6–13 years (unadjusted means). Significant progression is defined as >0.25 D change from baseline.
† No clinically meaningful change in refractive error means that there was less than a 0.25D increase in myopia from baseline as measured by cycloplegic autorefraction. (p<0.0001).
