Outcomes
Primary outcome [1] 0 0
Higher Order Root Mean Square (HO RMS) - Near Target in Downgaze With Natural Blinking - Wavefront metric measured by COAS wavefront sensor while subject fixates a near digital device in a down-gaze position with natural blinking. The average HO RMS was reported for each lens. Lower values indicate better outcome.
Timepoint [1] 0 0
2 hours post insertion
Primary outcome [2] 0 0
Higher Order Root Mean Square (HO RMS) - Near Target in Downgaze With Controlled Blink - Wavefront metric measured by COAS wavefront sensor while subject fixates a near digital device in a down-gaze position with controlled blinking. The average HO RMS was reported for each lens. Lower values indicate better outcome.
Timepoint [2] 0 0
2 hours post insertion
Primary outcome [3] 0 0
Higher Order Root Mean Square (HO RMS) - Distance Target in Primary Gaze With Controlled Blink - Wavefront metric measured by COAS wavefront sensor while subject fixates a distant target in primary gaze with controlled blinking. The average HO RMS was reported for each lens. Lower values indicate better outcome.
Timepoint [3] 0 0
2 hours post insertion

Eligibility
Key inclusion criteria
1. Healthy males or females that are at least 18 to no more than 40 years of age.

2. The subject must read, understand, and sign the Statement of Informed Consent and
receive a fully executed copy of the form.

3. The subject must appear able and willing to adhere to the instructions set forth in
this clinical protocol.

4. The subject must possess a wearable pair of spectacles with distance vision correction
which provide satisfactory vision.

5. The subject is a current spherical soft contact lens wearer (defined as a minimum of 6
hours of lens wear per week for a minimum of 1 month prior to the study) or has
sufficient prior experience with soft contact lens wear (defined as a minimum of 30
days of lens wear during the last 5 years).

6. The subject's vertexed best sphere distance refraction must be between -0.75 and -5.00
D in both eyes.

7. Cylinder refraction less than or equal to -0.75 D in both eyes (any axis).

8. The subject must have corrected visual acuity of 20/20 or better in each eye.
Minimum age
18 Years
Maximum age
40 Years
Gender
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
1. Currently pregnant or lactating (subjects who become pregnant during the study will be
discontinued).

2. Any ocular or systemic allergies or diseases that may interfere with contact lens
wear.

3. Any systemic disease, autoimmune disease, or use of medication, which may interfere
with contact lens wear.

4. Any known hypersensitivity or allergic reaction to contact lens solutions or sodium
fluorescein dye.

5. Any previous ocular or intraocular surgery (e.g. radial keratotomy, PRK, LASIK, etc.)

6. Current wearers of rigid or hybrid contact lenses.

7. Entropion, ectropion, extrusions, chalazia, recurrent styes, glaucoma, history of
recurrent corneal erosions, aphakia, or moderate or above corneal distortion by
keratometry.

8. Infectious diseases (e.g. hepatitis, tuberculosis) or an immuno-suppressive disease
(e.g. HIV).

9. History of binocular vision abnormality or strabismus.

10. Employee of the investigational clinic (e.g. Investigator, Coordinator, Technician).

11. Clinically significant (grade 3 or 4) corneal edema, pterygium, corneal
vascularization, corneal staining, or any other abnormalities of the cornea or
conjunctiva which may interfere with the study measurements.

12. Strabismus, suppression or amblyopia.

13. Any ocular infection.
