Inclusion Criteria
- •They are of legal age (18 years) and capacity to volunteer.
- •They understand their rights as a research subject and are willing to sign a Statement of Informed Consent.
- •They are willing and able to follow the protocol.
- •They would be expected to attain at least 6.9 (20/30) in each eye with the study lenses.
- •They are able to wear contact lenses which have a back vertex power of -1.00 to -6.00DS.
- •They have a maximum of 1.00D of refractive astigmatism (i.e. < 1.00 DC).
- •They have worn soft contact lenses within six months of starting the study.
Exclusion Criteria
- •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 are aphakic.
- •They have had corneal refractive surgery.
- •They have any corneal distortion resulting from previous hard or rigid lens wear or has keratoconus.
- •They are pregnant or lactating.
- •They have grade 2 or greater of any of the following ocular surface signs: corneal edema, corneal vascularization, corneal staining, tarsal conjunctival changes or any other abnormality which would normally contraindicate contact lens wear.
- •They have any infectious disease (e.g., hepatitis) or any immunosuppressive disease (e.g., HIV).
- •They have diabetes.
- •They are currently taking part in any other clinical study or research.

Outcomes
Primary Outcomes
Distance Visual Acuity
Time Frame: 1 week
logarithm of the minimum angle of resolution (logMar) ideal is 0.0 and represents 20/20 Snellen acuity. logMar values \> 0.00 indicate vision poorer than the ideal and values \<0.00 indicate vision greater than the ideal.
Secondary Outcomes
- Lens Comfort(1 week)
