Comparison of myopia control efficacy between single vision and highly aspherical Lenslet spectacle lenses in children with low myopia: a 1-year retrospective study

Objective: This study aimed to evaluate the effectiveness of Single Vision Lenses (SVL) and Highly Aspherical Lenslets (HAL) lenses in the management of low myopia. Methods: This retrospective study included school-age children (aged 6-12 years) diagnosed with low myopia who were treated at Chengdu Third People's Hospital from January 2022 to August 2025. Patients were divided into two groups based on their myopia control intervention: the SVL group and the HAL group. Subgroup analyses were subsequently performed within both groups according to age. The progression in mean spherical equivalent refraction (SER) and axial length (AL) was compared among the different groups and subgroups. Results: < 0.05). Conclusion: Single-vision lenses provide only minimal control of myopia progression, whereas specially designed lenses such as HAL lenses effectively slow myopia development-especially by curbing axial elongation. Age is also a critical factor: even with HAL lenses, axial growth remains pronounced in children under 8 years and is more difficult to control. For those who develop myopia at a younger age, combined pharmacological interventions may offer a better strategy than optical correction alone.
