1 Week Crossover Study Between Two Soft Contact Lenses

Inclusion Criteria

• Are 8 to 18 years of age (inclusively)
• Have read, signed and dated:
• Age 18 - The Participant Informed Consent Form (participant only)
• Age 12-17 - The Parental Permission Form (participant and parent)
• Age 8-11 - The Parental Permission Form (parent) and Assent form (participant)
• Are willing and able to follow instructions and maintain the appointment schedule.
• Are habitual daily wearers of spherical single vision soft contact lenses to correct for distance vision in each eye, including myopia control soft contact lenses as below-
• Currently wears spherical soft contact lenses or myopia control soft contact lenses.
• Have a pair of wearable back-up spectacles.
• Are willing and able to wear contact lenses for at least 10 hours a day, 6 days a week while in the study.
• Are myopic with subjective refraction: -0.75D to -7.00D spherical, with an astigmatism ≤ -0.75D in each eye with maximum spherical equivalent anisometropia of 1.00D
• Are correctable to a visual acuity of +0.10 logMAR or better (in each eye) with sphero-cylindrical subjective refraction.
• Have clear corneas with no corneal scars or any active ocular disease.
• Can be fit with the study contact lenses with a power between -0.75 and -7.00 DS; this translates to best corrected vision sphere refraction that vertexes to a CL power between -0.75 and -7.00 (inclusive) at screening visit.
• Demonstrate an acceptable fit with the study contact lenses.
• Demonstrate that they can safely and independently insert and remove contact lenses at the screening/fitting visit.

Exclusion Criteria

• Have taken part in another clinical research study within the last 14 days.
• Are currently habitual wearers of toric contact lenses.
• Have worn any rigid contact lenses or ortho-keratology contact lenses in the past 30 days.
• Are an extended contact lens wearer (i.e., sleeping with their contact lenses).
• Are on ongoing atropine treatment for myopia control.
• Have a difference of > 1.0 D in best vision sphere subjective refraction between eyes.
• Have amblyopia and/or strabismus/binocular vision problem.
• Have any known active ocular disease, allergies and/or infection.
• Have a systemic condition that in the opinion of the investigator may affect a study outcome variable.
• Are using any systemic or topical medications that in the opinion of the investigator may affect a study outcome variable.
• Have a known sensitivity to the diagnostic pharmaceuticals to be used in the study.
• Have undergone refractive error surgery or intraocular surgery.
• Are a member of CORL directly involved in the study.
