Inclusion criteria
1. Are at least 18 years of age and have capacity to consent; 2. Have understood and signed an information consent form; 3. Are an adapted soft contact lens wearer (worn for at least 3 months); 4. Have a contact lens prescription of -1.00DS to -6.00DS (inclusive) in each eye; 5. Have a refraction with a cylinder component of no more than -0.75DC in each eye; 6. Can achieve a best spectacle-corrected visual acuity in each eye of +0.10 logMAR or better.
Exclusion criteria
1. Participation in a contact lens or contact lens care product clinical trial in the previous 30 days; 2. Have any known active anterior segment disease and/or infection or slit lamp findings that would contraindicate contact lens wear; 3.
