• Have a refraction with a cylinder component of no more than -0.75DC in each eye;
• Can achieve a best spectacle-corrected visual acuity in each eye of +0.10 logMAR or better.

Exclusion criteria

• Participation in a contact lens or contact lens care product clinical trial in the previous 30 days;
• Have any known active anterior segment disease and/or infection or slit lamp findings that would contraindicate contact lens wear;
