  • Is aged 40-75 years, inclusive and has full legal capacity to volunteer.
  • Has read and understood the participant information sheet.
  • Is willing and able to follow instructions and maintain the appointment schedule.
  • Is able to participate in Parts A and B related to this work.
  • Has a contact lens spherical prescription between +10.00 to -10.00D (inclusive).
  • Has an Add component to their spectacle refraction (between +0.75 and +2.50DS).
  • Has astigmatism between -0.75 and -5.75DC (based on the vertexed ocular refraction in each eye.
  • Can be satisfactorily fitted with the study lenses.
  • Is correctable to a visual acuity of 20/40 (0.30 logMAR) or better (in each eye) with their habitual vision correction or 20/25 (0.10 logMAR) best-corrected.
  • They have successfully worn soft contact lenses in the last six months
  • Has clear corneas and no active ocular disease.
  • Has not worn lenses for at least 12 hours before the examination.
  • Has an up-to-date pair of spectacles.

排除标准

  • Has never worn contact lenses before.
  • Has any systemic disease affecting ocular health.
  • Is using any systemic or topical medications that will affect ocular health.
  • Has any ocular pathology or severe insufficiency of lacrimal secretion (moderate to severe dry eyes) that would, in the opinion of the investigator, affect the wearing of contact lenses.
  • Has persistent, clinically significant corneal or conjunctival staining using sodium fluorescein dye that would, in the opinion of the investigator, be problematic for their participation in the study.
  • Has any clinically significant lid or conjunctival abnormalities, active neovascularization or any central corneal scars.
  • Is aphakic.
  • Has undergone corneal refractive surgery.
  • Has a history of anaphylaxis or severe allergic reaction.
