Inclusion criteria
1. Age 18 to 45 years (inclusive) 2. Habitual soft spherical contact lens wearer (current prescription) 3. Refractive error of -6.00 to -0.50DS or +0.50 to +6.00DS and less than or equal to 0.75DC as vertexed to the corneal plane 4. Anisometropia no greater than 1.50D, based on vertexed manifest refraction spherical equivalent 5. Can achieve visual acuity of at least 20/25 in each eye with spherical equivalent manifest refraction
Exclusion criteria
1. Active anterior segment infection, inflammation or abnormality that would contraindicate contact lens wear 2. Use of systemic or ocular medication that would contraindicate contact lens wear 3. Used gas permeable/hard contact lenses (including orthokeratology) in the previous 3 months 4. Participation in a contact lens or lens care product trial in the previous 30 days
