Defocus-Enhanced vs. Single Vision Spectacles in Myopia Control Visual Function Training

Comparative Study of Visual Function Training With Defocus-Enhanced Spectacles vs. Single Vision Spectacles on Myopia Control in Children

The purpose of this study is to compare the effectiveness of vision function training using defocus-enhanced spectacles (DIMS) versus single vision spectacles combined with vision function training in controlling myopia progression in children aged 6-18 years.

Inclusion Criteria:

• Aged 6-18 years.
• Diagnosed myopia with SER between -0.50D and -4.00D.
• Astigmatism ≤ 2.50DC.
• Anisometropia < 1.25D.

Exclusion Criteria:

• Suspected genetic syndromes (e.g., Stickler, Marfan).
• Other eye diseases (e.g., glaucoma, cataracts, retinal abnormalities, strabismus).
• Myopia progression <0.50D SER in the last year.
