  • 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.

排除标准

  • 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.

结局指标

主要结局

Corrected Distance Monocular Visual Measurement Reported as Visual Acuity (VA)

时间窗: 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.

Overall Vision Quality

时间窗: 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.

Overall Comfort

时间窗: 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.

Overall Handling

时间窗: 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.

次要结局

  • Overall Lens Fit(1 week of wear, replacing lenses daily)
