Outcome Measures

Primary Outcomes (5)

  • Visual Acuity Using logMAR

    Assessment of visual performance using the Bailey-Lovie logMAR visual acuity test chart and procedures for carrying out an over-refraction

    Dispense and follow-up, approximately one hour (1hr) of lens wear for each lens type worn

  • Lens Fit - Horizontal Centration

    Assessment of horizontal centration of lens on eye

    Dispense and follow-up, approximately one hour (1hr) of lens wear for each lens type worn

  • Lens Fit - Vertical Centration

    Assessment of vertical centration of lens on eye

    Dispense and follow-up, approximately one hour (1hr) of lens wear for each lens type worn

  • Lens Fit - Corneal Coverage of Lens

    Assessment of corneal coverage of lens on eye

    Dispense and follow-up, approximately one hour (1hr) of lens wear for each lens type worn

  • Lens Fit - Movement of Lens

    Assessment of movement of lens on eye

    Dispense and follow-up, approximately one hour (1hr) of lens wear for each lens type worn

Eligibility Criteria

Age18 Years - 40 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • They are of aged 18-40 and have capacity to volunteer.
  • 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 agree not to participate in other clinical research for the duration of this study.
  • They have a contact lens spherical prescription between -1.00 to - 6.00D (inclusive)
  • They have a spectacle cylindrical correction of -0.75D or less in each eye (based on the ocular refraction).
  • They can attain at least 0.10 logMAR distance high contrast visual acuity in each eye with the study lenses within the available power range.
  • They currently use soft contact lenses or have done so in the previous six months.

You may not qualify if:

  • 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 have had cataract surgery.
  • 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 lactating.
  • They have any ocular abnormality which would, in the opinion of the investigator, normally contraindicate contact lens wear.
  • They have any infectious disease which would, in the opinion of the investigator, contraindicate contact lens wear or pose a risk to study personnel; or they have any immunosuppressive disease (e.g. HIV), or a history of anaphylaxis or severe allergic reaction.
  • They have taken part in any other contact lens or care solution clinical trial or research, within two weeks prior to starting this study.
