Using DIMS Glasses to See if Myopia Progression Slows in Kids
Official title: Inhibition of Myopia Progression With Optical Devices
Run by Semmelweis University · NCT07698977 · Data updated 2026-11-12
This observational study tests whether wearing DIMS glasses in children and teens with myopia can slow progression, considering factors like outdoor time and family history.

Is this trial a fit for you?
✓Likely a good fit
Ideal participants are 6–15 years old with myopia (−0.50 to −10.0 D) wearing myopia-control glasses and able to attend follow-up visits.
✕Probably not a fit
Children with very rapid progression, pathological myopia, or those unable to adhere to follow-up schedules may not experience benefit.

What this trial studies
This is a self-controlled observational study focusing on pediatric and adolescent myopia progression while wearing Defocus Incorporated Multiple Segments (DIMS) glasses during waking hours. The study collects data on refractive changes and environmental factors, including time spent outdoors and residence, over up to 24 weeks. Participants aged 6–15 with cycloplegic spherical equivalents between −0.50 and −10.0 diopters wear DIMS lenses to examine how progression changes with age and lifestyle. Diaries document subjective symptoms and environmental inputs to correlate with any changes in myopia progression. The primary aim is to observe real-world effects of these optical devices on rate of progression in this population.
Why it matters
Potential benefit: If successful, the approach could provide a practical option to slow myopia progression in children and adolescents.
How similar studies have gone: Previous work with DIMS lenses has shown potential slowing of myopia progression in similar pediatric populations, though this exact self-controlled observational design is comparatively novel.
