About
This is a two-arm parallel, non-masked, bilateral, non-dispensing study with one Test arm and one concurrent, non-randomized Control arm to evaluate the one-eye optical performances of the test soft contact lens and compare with eyes treated with orthokeratology.

Inclusion and exclusion criteria
Inclusion Criteria:
Potential subjects must satisfy all of the following criteria to be enrolled in the study:
Pediatric subjects (<18 years old) must read (or be read to), understand, and sign the Statement of Information and Assent and receive a fully executed copy of the form.
Adult subjects (≥18 years old) and parent(s) or legal guardian(s) of pediatric subjects must read, understand and sign the Statement of Informed Consent and receive a fully executed copy of the form.
Appear able and willing to adhere to the instructions set forth in this clinical protocol.
Between 7 and 25 years of age (inclusive).
Have normal eyes (i.e., no ocular medications or infections of any type).
Vertex-corrected distance subjective best-sphere refraction must be between -1.00D and -5.00D (inclusive) in each eye.
Cylindrical refraction must be 1.00D or less in each eye, by subjective sphero-cylindrical refraction.
Have sphero-cylindrical best-corrected visual acuity of 20/25 or better in each eye.
Below inclusion criterion is for subjects to be enrolled to the Control group only:
Are existing orthokeratology patients whose current treatment has been stabilized for at least 1 months and with complete pre-treatment record, e.g., spherocylindrical refraction and corneal topography. Pre-treatment wavefront aberration measures are preferred by not required.
Exclusion Criteria:
Potential subjects who meet any of the following criteria will be excluded from participating in the study:
9 . Any Grade 3 or greater slit lamp findings (eg, edema, corneal neovascularization, corneal staining, tarsal abnormalities, and conjunctival injection) on the FDA scale.
10 . Any ocular abnormality that is contraindicated contact lens wear. 11 . Any corneal scar within central 5mm 12 . Binocular vision abnormality, intermittent strabismus or strabismus. Below exclusion criteria are for subjects to be enrolled to the Test group only 13 . Current or recent (within 30 days from enrollment) rigid lens wearers. 14 . History of orthokeratology treatment. 15. Any corneal distortion resulting from ocular diseases or previous hard or rigid gas permeable contact lens wear.
