Outcome Measures
Primary Outcomes (3)
Overall Comfort
Overall Comfort will be assessed using vertical visual analogue scales (0-100) (0 - Causes Pain. Cannot be tolerated, 20 -Very uncomfortable, very irritating or annoying, 40 - Slightly uncomfortable, just irritating or annoying, 60 - Comfortable. Noticeable but not irritating, 80 - Very comfortable. Just felt occasionally, 100 - Excellent. Cannot be felt).
One Month
Comfort on Insertion
Comfort on insertion will be assessed using vertical visual analogue scales (0-100) (0 - Causes Pain. Cannot be tolerated, 20 -Very uncomfortable, very irritating or annoying, 40 - Slightly uncomfortable, just irritating or annoying, 60 - Comfortable. Noticeable but not irritating, 80 - Very comfortable. Just felt occasionally, 100 - Excellent. Cannot be felt).
One Month
Comfort Before Removal
Comfort before removal will be assessed using vertical visual analogue scales (0-100) (0 - Causes Pain. Cannot be tolerated, 20 -Very uncomfortable, very irritating or annoying, 40 - Slightly uncomfortable, just irritating or annoying, 60 - Comfortable. Noticeable but not irritating, 80 - Very comfortable. Just felt occasionally, 100 - Excellent. Cannot be felt).

Eligibility Criteria
You may qualify if:
- They are aged 18-50 and have 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 are an existing wearer of reusable, single vision, spherical soft contact lenses.
- They have a contact lens spherical prescription between -1.00 to - 6.50D (inclusive)
- They have a spectacle cylindrical correction of -1.00D or less in each eye.
- At dispensing, they can attain at least 0.20 logMAR distance high contrast visual acuity in each eye with the study lenses within the available power range.
- They are willing to comply with the wear schedule (at least five days per week and for at least eight hours per day).
- They agree not to participate in other clinical research for the duration of the study.
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 breastfeeding.
- 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.
