Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Be of legal age (i.e. 18 years)
* Be of Asian descent and have -Asian eye‖ identifying features (see Appendix A)
* Be mentally competent, willing and able to sign a written informed consent form.
* Have contact lens distance sphere requirement in the range 1.00D to 6.00D.
* Have spectacle astigmatism \<1.25D in each eye
* Currently wear soft contact lenses (for at least 3 months prior to the trial ) without experiencing difficulties or contact lens related complications
* Have had an oculo-visual examination within the previous 12 months.
* Have normal eyes with no evidence of abnormality or disease. For the purposes of this study a normal eye is defined as one having:

* No evidence of lid abnormality or infection
* No conjunctival abnormality or infection
* No clinically significant slit lamp findings (i.e. edema, staining, scarring, vascularization, infiltrates or abnormal opacities)
* No other active ocular disease

Exclusion Criteria

* Requires concurrent ocular medication.
* Clinically significant (Grade 3 or 4) corneal staining (FDA scale), corneal stromal haze, corneal vascularization, tarsal abnormalities, bulbar hyperemia, limbal hyperemia, or any other abnormality of the cornea that would contraindicate contact lens wear.
* Has had refractive surgery.
* Has had any anterior ocular surgery. Has had any other ocular surgery or injury within 8 weeks immediately prior to enrolment for this study.
* History of abnormal lachrymal secretions.
* Pre-existing ocular irritation that would preclude contact lens fitting.
* Keratoconus or other corneal irregularity.
* Extended lens wear in last 3 months.
* PMMA, hybrid or RGP lens wear in the previous 8 weeks
* Any systemic illness which would contraindicate lens wear or the medical treatment of which would affect vision or successful lens wear.
* Has diabetes
* Known/reported infectious disease (e.g., hepatitis, tuberculosis) or an immunosuppressive disease (e.g., HIV).
* History of chronic eye disease (e.g. glaucoma or ARMD).
* Pregnancy, lactating, or planning a pregnancy at the time of enrolment.
* Participation in any concurrent clinical trial or in last 30 days.
* Family member or employee of the clinical site, investigator or other study staff.
* Currently wears habitual contact lenses on an EW basis.
