Criteria

Inclusion Criteria:

  • They are of legal age (18 years) and capacity to volunteer.
  • They understand their rights as a research subject and are willing to sign a Statement of Informed Consent.
  • They are willing and able to follow the protocol.
  • They would be expected to attain at least 6/9 (20/30) in each eye with the study lenses.
  • They are able to wear contact lenses with a back vertex power of -1.00 to -6.00DS.
  • They have a maximum of 1.00D of refractive astigmatism (i.e. ≤ 1.00 DC).
  • They have successfully worn contact lenses within six months of starting the study.

Exclusion Criteria:

  • They have an ocular disorder which would normally contra-indicate contact lens wear.
  • They have a systemic disorder which would normally contra-indicate 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 has keratoconus.
  • They are pregnant or lactating.
  • They have grade 2 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 any infectious disease (e.g. hepatitis) or any immunosuppressive disease (e.g. HIV).
  • They have diabetes.
  • They have taken part in any other clinical trial or research, within two weeks prior to starting this study.
