Brief Summary
This will be a controlled and randomized, single-masked, crossover study in which 48 subjects will use the Biofinity Contact Lens (comfilcon A) with each of the two lens care products ('solutions'), (Synergi and Biotrue Multi-purpose Solution) for one month each. Follow-up visits for each solution will take place at one week, two weeks and four weeks: with a one-week 'wash-out' period between the solutions. Key outcome measures for this study include biomicroscopic and subjective responses to the lens/solution combinations.

- They are of legal age 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 - 0.50 to - 6.00 (inclusive)
- They have a spectacle cylindrical correction of -1.00D (Diopters) 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 silicone hydrogel soft contact lenses.
- They are willing to comply with the wear schedule (at least 5 days per week, ≥8 hours/day).
You may not qualify 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.
