Description
Inclusion Criteria:
- Normal eyes with no use of ocular medications.
- Be of legal age of consent and sign Informed Consent document. If under legal age of consent, legally authorized representative must sign Informed Consent document and subject must sign Assent document.
- Willing and able to wear spherical contact lenses for protocol-specified timeframe within the available range of powers (-1.00 D to -6.00D in 0.25D steps).
- Visual acuity with study lenses 20/25 or better.
- Cylinder less than or equal to 0.75 D.
- Currently wearing daily disposable lenses.
- Other protocol-defined inclusion criteria may apply.
Exclusion Criteria:
- Anterior segment infection, inflammation, or abnormality.
- Any active anterior segment ocular disease that would contraindicate contact lens wear.
- Any use of systemic medications for which contact lens wear could be contraindicated as determined by the investigator.
- History of refractive surgery or irregular cornea.
- Eye injury within twelve weeks immediately prior to enrollment for this trial.
- Currently enrolled in any clinical trial.
- Other protocol-defined exclusion criteria may apply.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Corrected Distance Monocular Visual Measurement Reported as Visual Acuity (VA)
Time Frame: 1 week of wear, replacing lenses daily
|
As tested for each eye individually while wearing study lenses.
VA was measured using a Snellen chart, which was converted into logMAR units (logarithm of the minimum angle of resolution).
A 20/20 Snellen acuity equated to a logMAR acuity of 0.0 and was considered normal distance eyesight.
Positive logMAR values indicated poorer vision, and negative values denoted better visual acuity.
|
1 week of wear, replacing lenses daily
|
Overall Comfort
Time Frame: 1 week of wear, replacing lenses daily
|
As interpreted by the participant and recorded on a questionnaire as a single, retrospective evaluation of 1 week of wear time.
Overall comfort was evaluated binocularly and rated on a 10-point scale, with 1 being poor and 10 being excellent.
|
1 week of wear, replacing lenses daily
|
Overall Vision Quality
Time Frame: 1 week of wear, replacing lenses daily
|
As interpreted by the participant and recorded on a questionnaire as a single, retrospective evaluation of 1 week of wear time.
Overall vision quality was evaluated binocularly and rated on a 10-point scale, with 1 being poor and 10 being excellent.
|
1 week of wear, replacing lenses daily
|
Overall Handling
Time Frame: 1 week of wear, replacing lenses daily
|
As interpreted by the participant and recorded on a questionnaire as a single, retrospective evaluation of 1 week of wear time.
Overall handling was evaluated binocularly and rated on a 10-point scale, with 1 being difficult and 10 being easy.

Time Frame |
---|---|---|
Overall Lens Fit
Time Frame: 1 week of wear, replacing lenses daily
|
As assessed for each eye individually by the investigator using a biomicroscope, which magnifies the appearance of the contact lens on the participant's eye.
Lens fit is reported on a 5-point scale, with 2=unacceptably loose, 1=acceptably loose, 0=optimal, -1=acceptably tight, and -2=unacceptably tight.
