The subject's distance spherical equivalent refraction (vertex corrected if ≥-4.25 D) must be in the range of -1.50 D to -5.50 D in each eye. 8. The subject's refractive cylinder must be ≤0.75 D in each eye. 9. The subject's ADD power must be in the range of +0.75 D to +2.50 D. 10. The subject must have distance best corrected visual acuity of 0.0 logMAR (20/20 Snellen, 5.0 on the China standard 5-point logMAR visual acuity scale) or better in each eye.

Have any known hypersensitivity or allergic reaction to sodium fluorescein. 17. Have Grade 3 or greater palpebral conjunctival observations or Grade 2 or greater slit lamp findings (e.g. corneal edema, corneal vascularization, corneal staining, bulbar injection, etc.) on the ISO 11980 classification scale, or any other corneal or ocular abnormalities which would contraindicate contact lens wear. 18. Have any current ocular infection or inflammation. 19. Have intraocular pressure in one or both eyes \>21mmHg 20. Have signs of any retinal disease/conditions that may interfere with any of the study assessments or are not stable and have potential to progress during the study.
