Exclusion criteria

Exclusion criteria: 1. Subjects who may have eye diseases that affect visual acuity or refractive errors (such as lens damage diseases such as cataracts, glaucoma, retinal detachment, etc.); 2. Systemic diseases: immune system diseases, central nervous system diseases, Down syndrome, asthma, severe cardiopulmonary function, severe liver and kidney dysfunction; 3. Overt strabismus or any other pathological changes in the eye or acute inflammatory disease of the eye in both eyes or in one eye; 4. Have used myopia prevention and control methods and drug treatment: such as atropine or piperazepine; Instrumental treatment: orthokeratology, multifocal soft lenses, multifocal hard lenses, functional glasses, etc; 5. Systemic or topical use of drugs that affect the efficacy evaluation within 3 months before screening, such as anticholinergics: atropine, piperazepine and other drugs; Cholinermic drugs: pilocarpine, ruta, etc; 6. Those who are allergic to drugs used in this study, such as atropine and cyclopentropite; 7. Those who have participated in other drug clinical trials within 3 months before screening; 8. Other conditions deemed unsuitable by the investigator; 9. Those with chronic mental illness or mental abnormalities; 10.
