Myopia Control Using Novel Soft Contact Lenses

Inclusion Criteria: * • Age at enrolment: 7 - 12 (both inclusive) years old Hong Kong Chinese schoolchildren * Refractive errors in terms of spherical equivalent refraction (SER) determined by cycloplegic autorefraction: -0.75 diopters (D) to -5.00D in both eyes * Astigmatism: equal or less than -1.00D * Anisometropia: equal or less than -1.75D * Previous myopia progression: * -0.50D (in SER) per year or more in 1 eye or both eyes OR Axial length elongation: 0.27mm/year in 1 eye or both eyes * If myopia is initially detected during screening, eligibility requires an SER below the 3rd percentile curve of refraction in either or both eyes (4) * Best corrected visual acuity: better than 0.04 LogMAR in both eyes * Ocular health: no abnormalities in both internal and external ocular health * Systemic health: no systemic interference with ocular vision functioning * Binocular vision: no strabismus and other binocular abnormalities * No medication or supplements that affect eye growth * Normal colour vision * No previous use of myopic control interventions such as red-light therapy, atropine, orthokeratology, specialized spectacle lenses and contact lenses and oral supplements for myopic control * Agree to maintain the visit schedule and be able to keep all appointments as specified in the informed assent and consent forms throughout study duration. * Agree to accept either the control or study lens as assigned by the randomization scheme * Agr…
