入选标准

  • Agrees to wear the study lenses on a daily wear basis without the use of ocular lubricants.
  • Has an up to date pair of glasses and is willing to wear these glasses at different times during the study.
  • Is correctable to a visual acuity of 6/6 or better with their habitual correction.
  • Is willing and able to follow product usage instructions and maintain the visit schedule.
  • Is at least 18 years of age and has full legal capacity to volunteer.
  • Can be successfully fitted with study lens type.
  • Has read, understood and signed an Information Consent Letter.
  • Has a distance contact lens prescription is between -0.50 D and -9.00 D
  • Has astigmatism of ≤ 1.00 D Cyl
  • Has normal binocular vision, i.e. no strabismus, no amblyopia, and anisometropia of ≤ 1.00D
  • Has no systemic disease affecting ocular health.
  • Is not using any systemic or topical medications that will affect ocular health, accommodative function, or the ocular physiological response to the contact lenses.
  • Has clear corneas and no active ocular disease.
  • Has no known ocular or systemic allergies, which could interfere with contact lens wear.
  • Has no lid or conjunctival abnormalities, neovascularization, limbal injection, bulbar injection or corneal staining, which in the investigator's opinion is clinically significant.
  • Has not worn rigid contact lenses in the last 30 days or has corneal distortion resulting from rigid lens wear.
  • Has not worn extended wear contact lenses in the last 30 days.
  • Has had an oculo-visual examination in the last two years

排除标准

  • Has any active ocular disease.
  • Has any lid or conjunctival abnormalities that may, in the opinion of the investigator, interfere with the wear of contact lenses.
  • Has edema, staining, clinically significant corneal opacity, dystrophy, vascularization or iritis as viewed by slit lamp. (Trace or grade 1 equivalent limbal and bulbar injection or corneal staining is permissible at the discretion of the investigator.)
  • Is using ocular lubricants or contact lens rewetting drops on a regular basis (at least once per day)
  • Is using topical ocular prescription or any topical over-the-counter medication.
  • Is actively involved in any other research/clinical study.
  • Has worn rigid lenses or soft lenses on an extended wear basis within the last 30 days.
