HOYA Shares Data from Study on MiYOSMART Chameleon Spectacles

April 16, 2024

BANGKOK — HOYA Vision Care has released the one-year data from its Early Experience Program (EEP) research that focused on the MiYOSMART sun solution Chameleon lenses. The photochromic lenses, released in April 2023, provide an all in-one solution to myopia management and protected outdoor activity by rapidly adapting to the level of sunlight, fading back to clear indoors in seconds.

The goal of the EEP was to evaluate the acceptance of MiYOSMART Chameleon spectacle lenses, as well as gain insights into the wearers’ habits. HOYA Vision Care proactively collected and analyzed data from 100 patients, aged 3 to 20 years old, located across Europe, Asia, Australia, and New Zealand.1 The results of the EEP showed that the MiYOSMART Chameleon spectacle lenses allowed rapid adaptation, with almost 80% (n=65) of patients adapting within one day to their new lenses.2 Of note, teenagers adapted to the new lenses as quickly as younger children.3 Additionally, 100% (n=65) of Chameleon spectacle wearers, both new wearers and experienced wearers, were satisfied with their visual performance during both outdoor and indoor activities and were comfortable with the fade back to clear, regardless of geographic location.4  

“The results of our Early Experience Program, showing great adaptation, tolerability, and overall satisfaction in patients of different ages and ethnicities is testament to HOYA’s research and commitment to providing innovative solutions. The findings around photophobia and increased wearing time highlight the potential of MiYOSMART Chameleon lenses to improve the outcomes of  myopia management in children, while being comfortable and retaining good visual performance,” said Marianne Goldwaser, Professional Affairs Manager at HOYA Vision Care. “We will continue touching base with ECPs and their patients to monitor their experience with MiYOSMART solutions and gain more valuable insights in the future.”  

As part of the study, HOYA Vision Care collected data on the effect of MiYOSMART Chameleon on wearing time, which showed significant wearing time, averaging 12 hours per day during weekdays, without the need to switch lenses when spending time outdoors.5 This extended wearing time translates to a longer treatment duration, which in turn has the potential of maximizing the effectiveness of myopia management in children.  

The EEP also demonstrated that wearing MiYOSMART Chameleon for two weeks significantly reduced light sensitivity in patients (n=12) receiving concurrent low-dose atropine treatment (22%  baseline; 50% after two weeks of wear).6 Although further research on a larger sample may be needed to draw conclusions, the results around combination treatment are promising.  

This data will be shared with eye care professionals and parents to answer questions surrounding the  MiYOSMART sun range and gain insights into patients’ habits and behaviors while wearing the product.
