1 Week Crossover Dispensing Study Between Two Soft Contact Lenses

Inclusion Criteria:

1. Are 8 to 18 years of age inclusive and have full legal capacity to volunteer;

2. Have read and signed and dated the Parental Permission Form (for those aged 16 andyounger); participant has read, signed and dated the study Information ConsentLetter (if aged 17 or 18 years) or Assent (aged 16 and younger);

3. Are willing and able to follow instructions and maintain the appointment schedule;

4. Are habitual daily wearers of spherical single vision soft contact lenses to correctfor distance vision in each eye;

5. Currently wears spherical soft contact lenses or myopia control soft lenses;

6. Have a pair of wearable back-up spectacles;

7. Are willing and able to wear contact lenses for at least 10 hours a day, 6 days aweek while in the study;

8. Are myopic with subjective refraction: -0.75D to -7.00D spherical, with anastigmatism ≤ -0.75D in each eye with maximum spherical equivalent anisometropia of 1.00D

9. Are correctable to a visual acuity of +0.10 logMAR or better (in each eye) withsphero-cylindrical subjective refraction;

10. Have clear corneas with no corneal scars or any active ocular disease;

11. 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 CLpower between -0.75 and -7.00 (inclusive) at screening visit.

12. Demonstrate an acceptable fit with the study lenses.

13. Demonstrate that they can safely and independently insert and remove contact lensesat the screening/fitting visit;

Exclusion Criteria:

1. Have taken part in another clinical research study within the last 14 days;

2. Are currently habitual wearers of toric lenses.

3. Have worn any rigid contact lenses or ortho-keratology lenses in the past 30 days

4. Are an extended lens wearer (i.e., sleeping with their lenses)

5. Are on ongoing atropine treatment for myopia control

6. Have a difference of > 1.0 D in best vision sphere subjective refraction betweeneyes;

7. Have amblyopia and/or strabismus/binocular vision problem

8. Have any known active ocular disease, allergies and/or infection;

9. Have a systemic condition that in the opinion of the investigator may affect a studyoutcome variable;

10. Are using any systemic or topical medications that in the opinion of theinvestigator may affect a study outcome variable;

11. Have a known sensitivity to the diagnostic pharmaceuticals to be used in the study;

12. Have undergone refractive error surgery or intraocular surgery;

13. Are a member of CORE directly involved in the study.
