Exclusion criteria:

(1) Single eye meet the inclusion criteria. (2) Suffering from systemic diseases that may affect the eye, such as diabetes, Down's syndrome, hyperthyroidism, rheumatoid arthritis, or other conditions that researchers consider unacceptable for ortho-k lenses. (3) Suffering from ocular disorders that may affect the fitting of ortho-k lens: e.g., vernal keratoconjunctivitis, dry eye disorder (BUT <5s), etc. (4) Suffering from strabismus. (5) Patients who are on or require drugs during the study period that may cause dry eye or affect visual acuity and corneal curvature, etc. (immunosuppressants, glucocorticoids, IOP-lowering medication, low concentrations of atropine). (6) Those who have a history of internal eye surgery. (7) Patients with abnormal intraocular pressure (normal IOP range is 10-21 mmHg, and the difference in bilateral IOP should be ≤5 mmHg). (8) Those who participated in other drug clinical trials within 90 days prior to screening, and those who participated in other medical device clinical trials within 30 days. (9) Those who cannot be followed up as prescribed by the researchers. (10) Patients whose examination results suggest contraindications to fitting or unsuitability for fitting ortho-k lenses. (11) Other conditions that the researchers consider unsuitable to participate in.
