Outcome Measures
Primary Outcomes (5)
Ocular Physiology
Ocular physiology assessment of senofilcon A and stenfilcon A lenses by biomicroscopy for the following: corneal staining, conjunctival hyperaemia, limbal hyperaemia, and conjunctival staining. Scale 0-4, 0.25 steps, 0=normal, 4=severe.
Baseline and 1 week
Overall Subjective Score of Lenses
Subjective responses will be evaluated for each pair using questionnaire. Scale 0-100, 0=extremely poor, 100=excellent.
Baseline and 1 week
Comfort
Subjective responses for comfort will be evaluated for each pair using questionnaire. Scale 0-100, 0=causes pain, cannot be tolerated, 100=excellent, cannot be felt.
Baseline and 1 week
Dryness
Subjective responses for dryness will be evaluated for each pair using questionnaire. Scale 0-100, 0=extremely poor, high levels of dryness, 100=excellent, no dryness.
1 week
Vision
Subjective responses for vision will be evaluated for each pair using questionnaire. Scale 0-100, 0=unacceptable, lens cannot be worn, 100=excellent.

Eligibility Criteria
You may qualify if:
- Subjects will only be eligible for the study if:
- They are of legal age (18) and capacity to volunteer.
- They understand their rights as a research subject and are willing and able to sign a Statement of Informed Consent.
- They are willing and able to follow the protocol.
- They agree not to participate in other clinical research for the duration of this study.
- They have a contact lens spherical prescription between -1.00 to - 6.00D (inclusive)
- They have a spectacle cylindrical correction of -0.75D or less in each eye.
- At dispensing, they can attain at least 0.10 logMAR distance high contrast visual acuity in each eye with the study lenses within the available power range.
- They currently use soft contact lenses or have done so in the previous six months.
- They are willing to comply with the wear schedule (at least six days per week and for at least eight hours per day).
You may not qualify if:
- Subjects will not be eligible to take part in the study if:
- They have an ocular disorder which would normally contra-indicate contact lens wear.
- They have a systemic disorder which would normally contra-indicate contact lens wear.
- They are using any topical medication such as eye drops or ointment.
- They have had cataract surgery.
- They have had corneal refractive surgery.
- They have any corneal distortion resulting from previous hard or rigid lens wear or have keratoconus.
- They are pregnant or lactating.
- They have any ocular abnormality which would, in the opinion of the investigator, normally contraindicate contact lens wear.
- They have any infectious disease which would, in the opinion of the investigator, contraindicate contact lens wear or pose a risk to study personnel; or they have any immunosuppressive disease (e.g. HIV), or a history of anaphylaxis or severe allergic reaction.
- They have taken part in any other contact lens or care solution clinical trial or research, within two weeks prior to starting this study.
- They currently wear either MyDay (daily) or the Acuvue Oasys (2 weekly) lens.
