• willing and able to sign the informed consent form
• ages 18 years or older
• Subjects must have owned spectacles or contact lenses prior to enrolment for this trial
• spherical power between -10.00 D and +10.00 D (at vertex distance 0 mm)
• astigmatic power equal to or less than 0.75 D

Exclusion Criteria:

• eye injury or surgery within 3 months immediately prior to enrolment for this trial
• pre-existing ocular irritation that would preclude contact lens fitting
• currently enrolled in an ophthalmic clinical trial
• evidence of systemic or ocular abnormality, infection or disease which is likely to affect successful wear of contact lenses use of as determined by the investigator

• current extended-wear users (sleep-in overnight)
• current monovision leans wearers
• pregnant women and nursing mothers
• best-corrected visual acuity worse than 6/9 (logMAR: +0.20; Snellen decimal: 0.63)
