New glasses could slow Kids' worsening eyesight
NCT ID NCT06034327
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether special spectacle lenses can slow the progression of myopia (nearsightedness) in children aged 6 to 8. About 150 kids will wear either the test lenses or regular lenses for up to 3 years. Researchers will measure changes in eye focus and eye length to see if the lenses help control myopia.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- special spectacle lenses designed to slow myopia progression
- What this could lead to
- If successful, these lenses could offer a simple, non-invasive way to slow worsening nearsightedness in young children, reducing the need for stronger prescriptions.
- What could go wrong
- This is a mid-stage trial with only 150 children, and results are based on 12-month predictions for 3-year effects. The lenses may not work for all children or may have limited long-term benefit.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Children 6 - 8 years of age (inclusive) at time of informed consent/assent; 2. Spherical equivalent refractive error between -0.75 and -4.50 D inclusive (by manifest refraction) in each eye; 3. Astigmatism if present, less than or equal to -1.25 DC (by manifest refraction) in each eye; 4. Best corrected visual acuity by manifest refraction of +0.10 logMAR (20/25 Snellen equivalent) or better in each eye; 5. The difference in spherical equivalent power between the two eyes (anisometropia based on manifest refraction) must be less than or equal to 1.50 D; 6. Agree to wear the assigned spectacles constantly except for sleeping, swimming, or other activities in which spectacle wear would be dangerous or otherwise not possible (minimum of 10 hours per day); 7. Ability to comply with study procedures, including high and low contrast visual acuity, axial length, and cycloplegic autorefraction measurements taken for both eyes at the baseline visit; 8. Willingness to participate in the trial for 24 months without contact lens wear; 9. The subject's parent(s) or legal guardian(s) must read, understand and sign the Statement of Informed Consent and receive a fully executed copy of the form. Exclusion Criteria: 1. Subject has previously or currently wears contact lenses (greater than 1-month usage); 2. Current or prior use of bifocals, progressive addition spectacle lenses 3. Current or prior use of any myopia control treatment (e.g., atropine, multifocal contact lenses, orthokeratology); 4. Amblyopia in either eye; 5. Strabismus by cover test at far (4 m) or near (40 cm) wearing distance correction; 6. Any ocular or systemic conditions that could influence refractive development or status \[e.g., keratoconus, congenital glaucoma, ocular trauma, diabetes, Marfan syndrome or other connective tissue disorder, Down's syndrome, family history of poor night vision (to prevent against enrolling subjects with congenital stationary night blindness)\]; 7. Known allergy to proparacaine, tetracaine, or tropicamide; 8. Participation in any investigational clinical study within 30 days of the Baseline visit; 9. Subject's sibling or other household member is already enrolled in this trial.
