Inclusion criteria

Inclusion criteria: 1. Age: 18 years old = 26.0mm, the astigmatism = 5.0; 4. In the past 24 months, the SER progression rate of both eyes = 0.10 mm/year (the difference in axial length between two visits / the number of days between visits * 365 days/year). The refraction and axial length of the two visits must be based on reliable refraction records and axial length examination results; 5. Fully understand the purpose of the clinical study. The subject voluntarily participates in this study and signs the informed consent form, and is willing to cooperate with the treatment and follow-up.

Exclusion criteria

Exclusion criteria: 1. One eye meets the inclusion criteria; 2. Presence of systemic diseases affecting the eyes; 3. Presence of strabismus or significant binocular visual dysfunction; 4. Abnormal intraocular pressure (normal range: 10–21 mmHg; interocular pressure difference <=5 mmHg); 5. Having received optical or pharmacological myopia control treatment within one year, such as orthokeratology, multifocal soft contact lenses, atropine, or peripheral defocus - designed spectacle lenses; 6. Unwilling to accept randomization or follow-up visits; 7. Excessively high requirements for visual quality; 8. Other conditions deemed unsuitable for inclusion by the researcher.
