About this trial
To evaluate the effectiveness of light-blocking lenses in promoting emmetropization and reducing anisometropia in children with hyperopic anisometropia, and to assess the impact of light-intercepting lenses on visual function in this population.
Eligibility criteria
Qualifiers

Best-corrected visual acuity of 0.0 logMAR or better in both eyes;
Ocular deviation with spectacles less than 10 prism diopters;
Disqualifiers
History of ocular trauma or eye surgery;
Presence of pathological abnormalities on anterior or posterior segment examination, or a history of organic ocular diseases such as cataract, glaucoma, corneal disease, or fundus disorders;
