Inclusion Criteria: * Spherical equivalent (SE) measured under cycloplegia using an autorefractometer, within the range 4 D ≤ SE ≤ -0.75 D for each eye * Not currently receiving, nor having received, any preventive treatment for myopic progression in the 12 months prior to inclusion (orthokeratology, soft defocus contact lenses, low-concentration atropine eye drops, corrective spectacles with peripheral defocus) * Myopic progression of at least -0.25 D in at least one eye during the year prior to inclusion (measurements documented by autorefractometer, with or without cycloplegia, or via previous optical prescriptions) or documented progression of axial length of +0.1 mm during the year prior to inclusion * Primary optical correction via spectacles (occasional use of contact lenses if applicable) or agreement to wear spectacles for at least 12 hours a day, every day * Enrolled in or a beneficiary of a social security scheme * Signed informed consent to participate in the study by the adult patient or by a person with parental authority for minor patients Exclusion Criteria: * Confirmed syndromic myopia or findings suggestive of syndromic myopia * Obvious strabismus or significant heterophoria * Corrected visual acuity \< 8/10 in at least one eye * A history of eye surgery (excluding eyelid surgery) in at least one eye * Hyperopia or non-myopic astigmatism * Anisometropia, i.e. a marked difference in correction between the two eyes * Advanced retinal disease in at least one eye, such as myopic maculopathy * Specific visual impairments in at least one eye requiring personalised treatments other than conventional corrective lenses * Intolerance to optical corrections (conventional lenses or lenses with peripheral defocus) * Patients subject to legal protection measures * Pregnant or breastfeeding women * Participation in another interventional clinical trial (drug clinical trial)
