Description
Inclusion Criteria:
- Be no less than 18 and no more than 39 years of age.
- Sign Written Informed Consent and investigator to record this on Case Report Form (See separate document).
- Be willing and able to adhere to the instructions set out in the protocol.
- Own a cell phone and be willing to receive text messages during the day.
- Be an existing successful daily wear soft contact lens. For the purposes of this study this means wearing lenses for at least 6 hours per day, 5 days per week for the last month.
- No extended wear in the last 3 months.
- Subjective refraction must result in a vertexed spherical contact lens prescription between -1.00 and -6.00D.
- Have refractive astigmatism less than or equal to 1.00D in both eyes.
- Achieve visual acuity of 6/9 (20/30) or better in each eye.
- Require a visual correction in both eyes (no monofit or monovision allowed).
- Does not require presbyopic correction (i.e. Not using any presbyopic correction and measured add power of less than +1.00D).
- Have normal eyes with no evidence of abnormality or disease. For the purposes of this study a normal eye is defined as one having:
- No amblyopia.
No evidence of lid abnormality or infection (including blepharitis/meibomitis).
- No conjunctival abnormality or infection.
- No clinically significant slit lamp findings (i.e. stromal edema, vascularization, infiltrates or abnormal opacities).
- No other active ocular disease.
Exclusion Criteria:
- Requires concurrent ocular medication.
- Clinically significant (Grade 3 or 4) corneal stromal haze, corneal vascularization, tarsal abnormalities, bulbar hyperemia, limbal hyperemia, or any other abnormality of the cornea that would contraindicate contact lens wear.
- Clinically significant corneal staining (Grade 3 in more than one corneal region per eye).
- Requires presbyopic correction (i.e. Not using any presbyopic correction and measured add power of less than +1.00D).
- Has had refractive surgery.
- Has had eye injury/surgery within 8 weeks immediately prior to enrolment for this study.
- Abnormal lacrimal secretions.
- Pre-existing ocular irritation that would preclude contact lens fitting.
- Keratoconus or other corneal irregularity.
- PMMA(polymethyl methacrylate), hybrid or RGP(rigid gas permeable) lens wear in the previous 8 weeks.
Does not require presbyopic correction (i.e. Not using any presbyopic correction and measured add power of less than +1.00D).
- Any systemic illness which would contraindicate lens wear or the medical treatment of which would affect vision or successful lens wear.
- Diabetic.
- Infectious disease (e.g., hepatitis, tuberculosis) or an immunosuppressive disease (e.g., HIV (Human immunodeficiency virus)).
- History of chronic eye disease (e.g. glaucoma or ARMD (age related macular degeneration)).
- Pregnancy, lactating or planning a pregnancy at the time of enrolment.
- Participation in any concurrent clinical trial or in last 30 days.

Measure Description |
Time Frame |
|---|---|---|
|
Overall Comfort Narafilcon B v. Nelfilcon A
Time Frame: After 1 week
|
Contact Lens User Experience (CLUE)TM questionnaire: A validated patient-reported outcomes questionnaire to assess patient-experience attributes of soft, disposable contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65.
Scores follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response.
