Brief Summary
This observational study aims to determine whether optical devices designed to slow myopia progression and/or environmental factors can prevent myopia progression in the pediatric and adolescent myopic population. The study aims to answer the following questions:
- Best corrected visual acuity test
- Stereopsis
- Automatic refractometry
- Bulbar axial length measurement In a follow-up study, researchers will compare myopia progression with environmental and baseline factors to learn about the long-term effects of DIMS lenses on myopia progression.

Outcome Measures
Primary Outcomes (2)
Best corrected visual acuity test
Zero is equivalent to no vision and 1.0 indicates the best visual acuity in decimal scale. Distance and near visual acuity is measured under standard conditions
up to 24 week
Bulbar axial length measurement
It is defined as the distance from the anterior surface of the cornea to the retinal pigment epithelium, measured in millimeters using optical device. An increase in axial length is characteristic of the elongation of the eye.
up to 24 week
Secondary Outcomes (1)
Stereopsis
up to 24 week
Study Arms (1)
Myopic cohort
Inclusion Criteria: * Participants must be between 6 and 15 years of age at the start of myopia progression treatment * Caucasian ethnicity * Refractive error measured under cycloplegia, expressed as spherical equivalent: between -0.50 Dsph and -10.0 Dsph * Wearing myopia-control glasses while awake * Participation in follow-up examinations every 6 months Exclusion criteria: * Pathological myopia (e.g., myopia onset before age 6, Stickler syndrome) * Premature birth before the 32nd week of gestation * Previous eye-opening surgery (e.g., lens removal) * Traumatic eye injury * Known connective tissue disorder (e.g., Marfan syndrome) * Irregular or improper use of progressive-lens glasses * Failure to attend the follow-up examinations scheduled every 6 months
Interventions
DIMS (Defocus Incorporated Multiple Segments) lenses wearing while awake
D.I.M.S. lenses are worn like normal glasses to correct myopia and, beyond that, their special design is intended to slow myopia progression via defocus lenslets. There is targeted myopic defocus produced by the mid-peripheral lenslets with positive power to inhibit eye length growth.
Eligibility Criteria
Participants (between 6 and 15 years of age) are wearing myopia progression treatment , namely D.I.M.S. lenses while they are awake. The wear these glasses to correct refractive error and to slow down myopia progression. At enrollment the refractive error measured under cycloplegia, expressed as spherical equivalent must be: between -0.50 Dsph and -10.0 Dsph.
You may qualify if:
- Participants must be between 6 and 15 years of age at the start of myopia progression treatment
- Caucasian ethnicity
- Refractive error measured under cycloplegia, expressed as spherical equivalent: between -0.50 Dsph and -10.0 Dsph
- Wearing myopia-control glasses while awake
- Participation in follow-up examinations every 6 months
You may not qualify if:
- Pathological myopia (e.g., myopia onset before age 6, Stickler syndrome)
- Premature birth before the 32nd week of gestation
- Previous eye-opening surgery (e.g., lens removal)
- Traumatic eye injury
- Known connective tissue disorder (e.g., Marfan syndrome)
- Irregular or improper use of progressive-lens glasses
- Failure to attend the follow-up examinations scheduled every 6 months
