Eligibility Criteria
Inclusion Criteria
- They are aged between 18 and 40 years.
- They understand their rights as a research subject and are willing and able to sign a Statement of Informed Consent.
- They are willing and able to follow the protocol.
- They have successfully worn contact lenses within six months of starting the study.
- They can be satisfactorily fitted with the study contact lenses.
- They have a contact lens spherical prescription between -0.25 to - 6.00D (inclusive) based on the ocular refraction.
- They have a spectacle cylindrical correction of -0.75D or less in each eye based on the ocular refraction.
- They own and habitually wear single vision spectacles.
- They can attain at least 0.20 logMAR distance high contrast visual acuity in each eye, with the study lenses.
- They agree not to participate in other clinical research while enrolled on this study.
Exclusion Criteria
- They have an ocular disorder which would normally contraindicate contact lens wear.
- They have a systemic disorder which would normally contraindicate contact lens wear.
- They are using any topical medication such as eye drops or ointment.
- They are aphakic.
- They have had corneal refractive surgery.
- They have any corneal distortion resulting from previous hard or rigid lens wear or have keratoconus.
- They are pregnant or breastfeeding.
- They have any ocular abnormality which would, in the opinion of the investigator, normally contraindicate contact lens wear or pose a risk to study personnel; or they have any immunosuppressive disease (eg HIV) or a history of anaphylaxis or severe allergic reaction.
- They have grade 3 or greater of any of the following ocular surface signs: corneal oedema, corneal vascularisation, corneal staining, tarsal conjunctival changes or any other abnormality, which would normally contraindicate contact lens wear.
- They have taken part in any other clinical trial or research, within two weeks prior to starting this study, which may impact on this particular work.
