Outcome Measures
Primary Outcomes (7)
Papillary Conjunctivitis
Swelling of the papillary (Papillary conjunctivitis) area of the eye was assessed using a slit-lamp. Comparison between the two study arms will be assessed using data generated from a slit-lamp examination, using an Efron scale with 0.1 unit increments. The Efron scale has a range of 0 (normal) to 4 (Severe) and is subjectively assessed for 0.1 increments by the clinician, with the higher the magnitude of the number the worse the score.
1 Year
Conjunctival Hyperemia
Comparison of the amount of redness in the conjunctival area of the eye, between the two study arms will be assessed using data generated from a slit-lamp examination, using an Efron scale with 0.1 unit increments. The Efron scale has a range of 0 (normal) to 4 (Severe) and is subjectively assessed for 0.1 increments by the clinician, with the higher the magnitude of the number the worse the score.
1 Year
Limbal Hyperemia
Swelling of the vessels in the limbal area of the eye using a slit lamp. Comparison between the two study arms will be assessed using data generated from a slit-lamp examination, using an Efron scale with 0.1 unit increments. The Efron scale has a range of 0 (normal) to 4 (Severe) and is subjectively assessed for 0.1 increments by the clinician, with the higher the magnitude of the number the worse the score.
1 Year
Corneal Staining
Abrasions in the cornea area of the eye using a slit lamp. Comparison between the two study arms will be assessed using data generated from a slit-lamp examination, using an Efron scale with 0.1 unit increments.
1 Year
Conjunctival Staining
Mild abrasions of the conjunctival area of the eye. Comparison between the two study arms will be assessed using data generated from a slit-lamp examination, using an Efron scale with 0.1 unit increments. The Efron scale has a range of 0 (normal) to 4 (Severe) and is subjectively assessed for 0.1 increments by the clinician, with the higher the magnitude of the number the worse the score.
1 Year
Corneal Neovascularization
New vascularization of the Cornea. Comparison between the two study arms will be assessed using data generated from a slit-lamp examination, using an Efron scale with 0.1 unit increments. The Efron scale has a range of 0 (normal) to 4 (Severe) and is subjectively assessed for 0.1 increments by the clinician, with the higher the magnitude of the number the worse the score.
1 Year
Differences in Subjective Comfort From the Contact Lens User Experience (CLUE) Questionnaire
The subjective comfort questionnaire CLUE, assesses the overall lens comfort. The CLUE Questionnaire is a validated patient-reported outcomes questionnaire to assess patient-experience attributes of soft, disposable contact lenses 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, with a range of 0-120. The differences between: (final visit and first visit) and then (final visit and 6 months) are reported.

Eligibility Criteria
You may qualify if:
- Able to read, comprehend and sign an informed consent (or parental consent/subject assent, as appropriate).
- Willing to comply with the study visit schedule.
- Ages 15 to 39.
- Has access to a cellular telephone with text messaging capabilities.
- Has a current pair of spectacles.
- 'Neophyte' - In this work, 'neophyte' will be taken to mean any subject who has never been dispensed contact lenses. A subject who has taken part in a non-dispensing clinical study or has been fitted with contact lenses in practice but never went on to actually wear the lenses, will also be classified as a 'neophyte'.
- Spherical contact lens (CL) prescription between -0.75D and -6.00D and spectacle cylinder equal to or less than 0.75 DC.
- Monocular best-corrected distance visual acuity (VA) ≥ 20/30 Snellen in each eye.
- Subject agrees to "intent" of wearing the CLs at minimum 6 hours/day for at least 4 days per week.
- They agree not to participate in other clinical research during the duration of this study.
You may not qualify if:
- Active ocular allergy, infection, injury, inflammation, or abnormality (e.g., keratoconus) that might interfere with soft contact lens wear.
- Prior corneal refractive surgery or corneal irregularity (e.g., keratoconus).
- Systemic disease, which might interfere with contact lens wear.
- Medication usage that may be associated with eye dryness.
- Use of any topical medication such as eye drops or ointment.
- Pregnant or lactating (by self-report).
- Aphakia.
- Grade 2 or greater of any of the following ocular surface signs: corneal edema, corneal vascularization, corneal staining, tarsal conjunctival changes or any other abnormality, which would normally contraindicate contact lens wear.
- Have participated in any other clinical trial or research in the two weeks prior to starting this study.
