Canadian eye care professionals are invited to attend a SightGlass Vision webinar on contrast management for myopia control in children, featuring new clinical data and perspectives from Canadian practice.
The webinar, Control the Contrast: From Theory to Practice with MiSight® Spectacle Lenses Powered by Diffusion Optics Technology™, will take place on July 22 at 7 p.m. ET / 4 p.m. PT.
The session will feature Vishakha Thakrar, OD, FAAO, FSLS, of Vaughan Vision Centre in Vaughan, Ontario; Fabio Carta, Dip. Optom, FBCLA, director of professional affairs at SightGlass Vision; and Nathalie Trottier, OD, FAAO, senior manager of professional and academic affairs Canada at CooperVision.
Carta will open the session with an overview of the science behind contrast management, followed by new two-year findings from SightGlass Vision’s CATHAY study. According to the company, the study showed that DOT® spectacle lenses, available in Canada as MiSight® Spectacle Lenses powered by Diffusion Optics Technology™, reduced average myopia progression and axial length progression compared with the control group after two years of wear.
Dr. Thakrar and Dr. Trottier will then focus on practical considerations for Canadian practice, including how the lenses are being prescribed for young patients and what clinicians may consider when adding the technology to their myopia management options.
MiSight® Spectacle Lenses powered by Diffusion Optics Technology™ are designed to mimic more natural contrast while providing a visual experience described as clinically equivalent to standard single-vision lenses. According to SightGlass Vision, the lenses have been worn by more than two million children worldwide.
The webinar is part of SightGlass Vision’s Control the Contrast initiative, which is intended to support education among eye care professionals on contrast management as an approach to myopia control.
Researchers at the University of Waterloo have developed a 3D-printing platform capable of producing patient-specific contact lenses in as little as 20 minutes.
The technology combines custom lens-design software, a new hydrophilic silicone formulation and a non-contact surface-finishing process. The researchers say the platform could eventually support the design, manufacture and dispensing of specialized contact lenses during a single visit to an optometrist.
A Potentially Faster Route to Customized Lenses
The platform is intended to address some of the time and complexity associated with fitting patients whose corneal profiles fall outside the parameters accommodated by standard lens designs.
For patients requiring highly customized rigid lenses, the fitting process may involve multiple diagnostic lenses, modifications and follow-up visits before an acceptable combination of fit, vision and comfort is achieved.
The Waterloo platform uses digital design and additive manufacturing to produce a lens with an inner surface matched to the patient’s corneal profile and an outer surface designed to provide the required refractive correction.
“We are very excited about this work because it brings us closer to contact lenses that are truly personalized,” said Dr. Shirley Tang, professor in Waterloo’s Department of Chemistry. “Our technology produces lenses with patient-specific surfaces for a precise fit while delivering the optical clarity and mechanical performance expected of commercial contact lenses.”
New Silicone Formulation Designed for 3D Printing
A central component of the platform is a hydrophilic silicone material developed specifically for vat photopolymerization printing.
While silicone materials offer the oxygen permeability and biocompatibility required for contact lens applications, conventional formulations are generally not suitable for additive manufacturing. The Waterloo team developed a new formulation intended to retain the necessary material properties while remaining compatible with the printing process.
“Our software designs a lens with an inner surface that precisely matches the patient’s cornea and an outer surface that provides the required vision correction,” said Dr. Sayan Ganguly, a research associate in Waterloo’s Department of Chemistry.
“The novel hydrophilic silicone material we created, combined with our manufacturing process, produces smooth, transparent lenses that are comfortable to wear.”
Surface-Finishing Process Improves Optical Quality
Layer-by-layer printing can create microscopic surface irregularities that may affect optical performance and lens comfort.
To address this issue, the researchers developed an ultra-thin, non-contact fluidization coating process designed to smooth the lens surface without altering its customized geometry or compromising its optical properties.
The complete platform integrates lens design, material development, printing and surface finishing into a digital manufacturing workflow.
Clinical Testing and Commercialization Still Ahead
Laboratory testing confirmed the biocompatibility of the printed lenses, and the research team is preparing for in vivo studies.
The technology therefore remains at the development stage and is not yet available for clinical use.
The researchers have filed a provisional patent for the hydrophilic silicone material and are preparing a full patent application.
The project is being advanced toward potential commercialization in collaboration with the Centre for Vision and Eye Research, a joint research institute of the University of Waterloo and Hong Kong Polytechnic University.
The platform received a Gold Medal at the Shanghai International Exhibition of Inventions in June 2026.
The study, “Patient-specific hard contact lenses fabricated by vat photopolymerization printing and non-contact fluidization coating,” was published in Materials & Design.

There may be seven wonders of the world, but through a child’s eyes, there are millions more. From spotting faces in everyday objects to discovering hidden details adults might miss, children see wonder in everyday moments. Yet many may not be seeing their world as clearly as they could. More than one in four kids in Canada have problems with their vision by school age and that number is rising*.
Specsavers Canada is encouraging families to protect that wonder and curiosity by making eye exams a regular part of their child’s healthcare routines. According to the Canadian Association of Optometrists (CAO), only about half of children under 19 are getting their eyes examined as often as recommended, even though many vision conditions are most effectively treated before age seven**.
“Kids experience the world with a unique sense of curiosity, imagination and wonder. Vision plays an important role in their development,” said Naomi Barber, Clinical Services Director at Specsavers Canada. “Routine eye exams can help ensure they have the vision they need to learn and engage confidently with the world around them.”
The CAO recommends children have their first eye exam between six and nine months, a second between ages two and five, and annual exams thereafter. Regular eye exams can help detect vision issues such as myopia (nearsightedness) early, allowing for interventions that slow its progression and support healthy vision as they grow.
“Many parents are surprised to learn how common vision problems can often be addressed when caught early,” continued Barber. “We want eye exams to feel like just another part of growing up so that kids get to fully experience the wonders of their world.”
Build around the idea of childhood wonder, Specsavers Canada will roll out a summer-long campaign that celebrates the unique way children experience the world through their eyes. By highlighting these moments of discovery, the campaign aims to encourage greater awareness for the importance of eye health from an early age, as children grow and explore.
Adapted from Specsavers UK’s successful Wonder campaign, the Canadian creative is anchored by the statistic that more than 1 in 4 children have a vision problem by school age. With summer in full swing, the message lands at a great time for parents to book an eye exam for their child before the new school year. Helping make the most of every moment of wonder, both in and out of the classroom.
Over the last decade, myopia management has advanced significantly across academic institutions, optometry schools, and industry, helping shift the conversation from simple refractive correction toward active intervention. Spectacle lenses, soft contact lenses, orthokeratology, and pharmacologic approaches have all contributed to that progress, and the evidence base supporting myopia control is stronger than ever.
Yet despite these gains, an important gap remains: myopia management is still not consistently embedded as standard of care in everyday clinical practice. The field has made substantial progress in knowledge, innovation, and professional awareness, but broader adoption of even basic myopia control remains one of the profession’s most pressing unfinished tasks.
Beyond Defocus
At the same time, the conversation within the field is moving beyond first-generation thinking. The modern question is not whether we can slow myopia progression, but how we can understand, refine, and optimize that effect more intelligently. In particular, the long dominant language of defocus may no longer be sufficient on its own to explain where the field is heading next.
Defocus remains an essential part of the story, but it increasingly appears to be only one component of a more complex visual and biological signaling system. Across both spectacle and contact lens development, growing attention is being paid to the possibility that aberration, contrast sensitivity, spatial frequency content, accommodative behaviour, and choroidal response may all play meaningful roles in regulating eye growth.
That is a significant conceptual shift. It suggests that the next frontier is not just lens design in the narrow optical sense, but a more refined form of retinal image quality engineering. Orthokeratology offers an example. Although often discussed through the framework of peripheral myopic defocus, its effects are unlikely to be explained by defocus alone. It also induces changes in higher-order aberrations, including spherical aberration, and may alter retinal image quality in ways that influence growth-regulating pathways. The same may be true, to varying degrees, for newer spectacle and soft contact lens designs, which do more than simply reposition focal planes. They also reshape local blur structure, contrast distribution, and the character of the visual stimulus across the retina.
Engineering the Retinal Image
Contrast sensitivity may allow us to understand light in the retina in new ways. The retina does not merely register whether light is in or out of focus; it responds to the strength, quality, and pattern of the image signal it receives. If contrast modulation and spatial frequency processing are shown to be more central to myopia control than previously appreciated, this could expand the design logic of future treatments. The aim would shift from correcting refractive error while adding a therapeutic defocus component, toward tailoring the overall retinal image environment in a more biologically informed way.
Such a shift may also help explain one of the field’s most persistent realities: not all children respond equally well to the same treatment. That is why the future is likely to involve not only better products, but more individualized treatment optimization. In time, treatment selection may depend less on broad categories alone. Spectacle lens, soft lens, orthokeratology, and atropine candidacy may be determined with streamlined or automated processes looking at a child’s specific optical, behavioural, and biometric profile. Baseline aberrations, pupil size, accommodative behaviour, contrast response, binocular status, peripheral optics, and axial growth pattern may all eventually inform more personalized decisions.
The Choroid as a Biological Bridge
Alongside these optical questions, the choroid has emerged as one of the most intriguing biological structures in current myopia research. Increasing evidence suggests that it may act as a dynamic intermediary between visual input and axial growth. Short-term choroidal thickening has been associated with myopia-inhibiting signals, while thinning appears linked to conditions that promote elongation. The choroid is not yet a routine clinical marker, but it may prove to be one of the most important bridges between mechanism and management.
Its relevance extends well beyond lenses. If choroidal behaviour forms part of the eye-growth signaling pathway, then it becomes easier to understand how light exposure, medications, and other less traditional interventions might influence the same system through different entry points. This is one reason the future of myopia management may become less siloed. Optical, pharmacologic, and environmental approaches may increasingly be understood not as competing philosophies, but as complementary strategies acting on interconnected mechanisms.
That broader view also strengthens the case for greater attention to pre-myopia. Once a child becomes myopic, some degree of accelerated growth may already be underway. The next phase of care may therefore focus more heavily on identifying children at risk before refractive onset, using age, refractive status, family history, axial length patterns, and, eventually, more refined biomarkers. The goal would not simply be to slow established progression, but to delay or even prevent onset where possible.
Lifestyle, Light and the Visual Environment
This is where lifestyle and everyday visual environment deserve a more central place in the conversation. Research remains limited in several areas that are highly relevant to modern family life, but limited evidence should not be mistaken for lack of importance. Parents increasingly ask about nutrition, light exposure, prolonged near work, school intensity, screen use, study habits, sleep, and general wellbeing. These are not fringe concerns. They reflect the real-world conditions in which myopia develops.
Of these, light exposure remains a compelling and clinically actionable factor. Time outdoors is consistently associated with reduced myopia onset, and its effects may involve dopamine signaling, retinal adaptation, and choroidal response. That alone should secure its place as a mainstream part of myopia counselling. But the conversation should not stop there. The modern child often spends long hours in sustained near work under highly demanding visual conditions, with short viewing distances, limited task breaks, and heavy digital device use. Even where evidence remains incomplete, school and studying ergonomics should become more routine topics in clinical practice: working distance, posture, regular breaks, print size, screen position, and the balance between near work and time outdoors.
Nutrition is more speculative, but still worth acknowledging in a balanced way. There is currently insufficient evidence to support specific nutritional prescriptions for myopia control, and the field should resist overstating what is not yet known. At the same time, it is increasingly difficult to maintain a model of ocular development that is entirely detached from systemic health. A balanced diet, healthy sleep, physical activity, and overall wellness may not yet be measurable as direct axial-length therapies, but they belong within a preventive framework of care.
Toward a Whole-Child Model of Care
That may be the deeper opportunity now facing the profession. Myopia management can evolve from a treatment conversation into a whole-child health conversation. Spectacle and contact lens innovation will remain central, and rightly so. But the next frontier may be defined just as much by integration as by invention: integrating optical mechanisms with biology, integrating treatment with prevention, and integrating lens-based care with the broader realities of children’s health and daily lives.
If the first era of myopia management proved that progression can be slowed, the next era may be about something more ambitious: understanding why children respond differently, refining treatment with greater precision, and bringing prevention, lifestyle, and wellbeing closer to the centre of care. That is what Myopia Management 2.0 may ultimately mean, not simply more intervention, but better understanding which translates to more sophisticated clinical decision making.
