Evidence you can trust.

Clinical studies are the foundation of any evidence-based treatment.

 They aim to:

  • Evaluate effectiveness of a treatment
  • Evaluate safety of a treatment
  • Provide answers to topics of interest regarding a specific treatment

This information can help you assess if a treatment is the right solution for  your child with an Eye Care Professional.

We carried out a lot of clinical studies that provide high-quality evidence, to give you the confidence when considering MiYOSMART as a treatment solution for your child.

Spectacle lenses that really work

  • A 2-year clinical study in Hong Kong showed that myopia progression slowed down on average by 60% in children that used MiYOSMART spectacle lenses, compared with regular single-vision spectacle lenses.2 Similar results were seen in a UK-based clinical study.3
  • Additionally, in the Hong Kong study, 1 in 5 children who wore MiYOSMART spectacle lenses had no myopia progression at all in the first 2 years.2

Suitable for most children

We’ve conducted multiple clinical studies in different age groups and parts of the world,2-4 so we are confident that MiYOSMART spectacle lenses are suitable for most children of different ages and backgrounds.

Based on a solid scientific theory 

The D.I.M.S. Technology used in MiYOSMART spectacle lenses is based on a well-established and widely accepted scientific theory.5,6

Well tolerated
with no long-term adverse events

• MiYOSMART spectacle lenses are generally well tolerated among children3, 9

• They are a non-invasive solution, unlike other treatments out there (like atropine or Ortho-K), and it usually only takes children a few days to adapt to their new MiYOSMART spectacle lenses

• Your child may occasionally notice blurred vision through the defocus zone of the lenses, but the central zone remains clear2, 3, 8, 9

• Some children experience ghost image, dizziness and headache, but these side effects are rare and short-lived2, 8

• A 6-year clinical study in Hong Kong showed no long-term side effects from wearing MiYOSMART spectacle lenses7

Safe on the road

MiYOSMART spectacle lenses don’t cause glare sensitivity or worsen contrast vision. Thus, they don’t impair vision in traffic, neither alone nor with low-dose atropine eye drops.10 This means that after a 2-week adaptation period, your child can go cycling with no distracting glare from traffic lights or other vision disturbances.


Compatible with atropine eye drops

MiYOSMART spectacle lenses work in synergy with low-dose atropine eye drops. In fact, recent clinical studies from Europe4 and China11 found that the combination treatment of MiYOSMART spectacle lenses and low-dose atropine eye drops was more effective, than MiYOSMART or atropine alone. However, this is a treatment decision that should be made under the supervision of an Eye Care Professional.

No 'bounce-back' effect

If your child stops their treatment with MiYOSMART spectacle lenses, myopia will not ‘bounce back’ to what it was before treatment.7 This is unlike other popular treatment methods, like high-dose atropine eye drops or orthokeratology.12, 13


MiYOSMART has not been approved for myopia management in all countries, including the U.S., and is not currently available for sale in all countries, including the U.S.

MiYOSMART spectacle lenses may not be able to address individuals’ conditions due to natural deficiencies, illness, pre-existing medical conditions and/or advanced age of consumers.
