A new lens design might stop adult nearsightedness from worsening

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Any gender, aged 18-30 years, inclusive. * Successful previous contact lens wearer * Documented ongoing myopia progression (at least 0.50D over past 2 years) * Refractive error meeting the following by cycloplegic autorefraction: * Myopia -0.50D to -5.00D SER in both eyes * Astigmatism (absolute value) ≤ 1.50 D in both eyes * Anisometropia \< 1.50 D SER. Best-corrected distance visual acuity (BCDVA) in current correction as follows: * 0.1 logMAR or better * Interocular difference ≤ 0.1 log MAR Exclusion Criteria: * Current or previous use of pharmacologic or optical myopia control treatment within the past 2 years. * Any ocular disease or abnormality affecting the cornea, lens, retina, iris, ciliary body, choroid, or sclera. * History of manifest strabismus, amblyopia, or nystagmus. * Previous eyelid, strabismus, intraocular, or refractive surgery. I- ntraocular pressure \>26 mmHg. * of premature birth (≥6 weeks before the due date). * Neurological disorders, genetic syndromes, or other conditions that would interfere with completion of study procedures. * Known allergy or hypersensitivity to fluorescein, proparacaine, or tropicamide. * Conditions associated with degenerative myopia or abnormal ocular anatomy (e.g., Marfan syndrome, Stickler syndrome, retinopathy of prematurity, keratoconus, lenticonus, or spherophakia). * Regular use of ocular medications, artificial tears, or wetting agents. * Current use of systemic medications that may affect contact lens wear, tear film, pupil size, accommodation, electrophysiology, or refractive state. * Diagnosis of or treatment for attention-deficit/hyperactivity disorder (ADHD) or a learning disability. * Systemic disease that may affect visual function (e.g., diabetes mellitus). * Ocular inflammation within 30 days before screening. * Slit-lamp findings that contraindicate contact lens wear (e.g., corneal scars, corneal neovascularization, giant papillary conjunctivitis). * Blepharospasm or other eyelid abnormalities that interfere with contact lens wear. * Any severe ocular or systemic condition that, in the investigator's judgment, would interfere with study participation or follow-up.
