Query!
Assessment method [1]
0
0
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.

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

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).

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.
