ANAHEIM, CA—September 30, 2026 —Visioneering Technologies, Inc. (VTI) proudly announce the final three-year results of PROTECT, a prospective, double-masked, multinational randomized controlled trial evaluating the NaturalVue® (etafilcon A) Multifocal 1 Day Contact Lens in myopic children. Ashley Tuan, OD, MS, PhD, Chief Medical Officer of Visioneering Technologies, will present the compelling findings at the American Academy of Optometry Annual Meeting in Anaheim, California.
Landmark Results Across Key Measures1,2
Over three years, children wearing NaturalVue Multifocal 1 Day demonstrated the following compared with a virtual control group:
Pioneering Optical Design, Now Backed by Randomized Controlled Clinical Evidence
With the successful completion of the PROTECT clinical trial, NaturalVue Multifocal 1 Day stands alone as the first and only catenary power curve soft contact lens design5,6 to demonstrate >1.00 D less myopic refractive progression over three years.1,2
“The PROTECT clinical trial adds important three-year double-masked, randomized controlled evidence to what we know about NaturalVue Multifocal 1 Day,” said Ashley Tuan, OD, MS, PhD. “What is especially meaningful is the breadth of the findings. We see a large refractive treatment effect together with significant slowing of axial elongation to the expected level for emmetropic children of these ages and ethnicities, providing a more complete picture of NaturalVue's performance in children with myopia.”
Every Diopter Matters
How much myopia a child develops over time matters for long-term ocular health. Independent of any single treatment, published research underscores the importance of magnitude. Slowing myopia by 1.00 D is estimated to reduce the likelihood of developing myopic maculopathy by approximately 40%7 and the risk of retinal detachment by approximately 23%.8
“Every diopter matters, which is why the magnitude of the completed PROTECT clinical trial results is important,” said Brett O'Connor, OD, FAAO*, Smith Eye Associates, Ponte Vedra, FL. “NaturalVue Multifocal 1 Day demonstrated 1.06 D less myopic refractive progression versus control at three years, along with a 0.58 mm reduction in axial elongation versus control.1,2 For eye care professionals managing pediatric progressive myopia, the amount of progression you can reduce matters for better long-term eye health and quality of life.”
Meaningful Results for Myopic Children
In the PROTECT clinical trial, children wearing NaturalVue Multifocal 1 Day showed eye growth similar to non-myopic children over 36 months:1,2
Protecting Vision for Tomorrow
The completed PROTECT clinical trial equips eye care professionals with a powerful evidence base to guide the long-term myopia-management decisions they make for children every day.
“Correcting a child's myopia today is only part of the opportunity,” said Jeff Pruett, Chief Operating Officer of Visioneering Technologies. “The broader goal is managing how much myopia each child develops over time, to protect their vision for tomorrow. The PROTECT study gives eye care professionals substantial new evidence to guide that choice, with results that are both statistically and clinically significant. It was rigorously designed: large, multinational, double-masked, randomized and controlled, and independently conducted, monitored, and managed. Now more than ever, it's time to prescribe NaturalVue Multifocal 1 Day."

About PROTECT
PROTECT (PROgressive Myopia Treatment Evaluation for NaturalVue Multifocal Contact Lens Trial; NCT05159765) is a three-year, prospective, multicenter, double-masked, randomized controlled trial conducted in the United States, Canada, Hong Kong, and Singapore. A total of 145 children aged 7 up to 13 years, with cycloplegic spherical equivalent refraction (CSER) of −0.75 D to −5.00 D and astigmatism of ≤ 1.00 DC, were randomized 2:1 to NaturalVue Multifocal 1 Day (NVMF) or single-vision contact lenses (SVCL). As planned, the SVCL group crossed over to NVMF at 24 months, so 36-month NVMF outcomes were compared with modeled control data.† Of the children enrolled, 126 completed the 36-month study. Outcomes were adjusted for age, sex, ethnicity, country, study site, and baseline value.**
The three-year PROTECT results provide clinical evidence on both key measures of myopia progression: cycloplegic spherical equivalent (CSER), measured by autorefraction, and axial length, measured by optical biometry (e.g., IOLMaster, Carl Zeiss Meditec).
About Visioneering Technologies

Results are from a single randomized trial and may not apply to patients outside the studied population. Individual results may vary. See the full PROTECT study report for study limitations, and the package insert for indications, contraindications, warnings and precautions.
** Values based on per-protocol cohort: baseline ages 7 to <13, baseline refraction −0.75 D to −5.00 D, n = 102 (p < 0.001).
† 36-month control values were derived from several complementary analyses, including SVCL projections (24-month SVCL patient data projected to 36 months) and a DyNaSynth™ Synthetic control matched to the SVCL group's baseline characteristics. The modeled control trajectories showed a high degree of concordance with published virtual control models.

In the PROTECT clinical trial, children wearing NaturalVue Multifocal 1 Day showed eye growth similar to non-myopic children over 36 months:1,2
- 59% progressed ≤0.25 D per year on average, consistent with the threshold commonly used to define non-progressive myopia.9
- 55% had axial growth within the emmetropic benchmark of the study.1,2
- Across all age groups studied, average axial growth trends stayed within published emmetropic growth ranges.¹⁰,¹¹
