  • The subject's refractive cylinder must be ≤0.75 D in each eye.
  • The subject's ADD power must be in the range of +0.75 D to +2.50 D.
  • The subject must have distance best corrected visual acuity of 20/20-3 or better in each eye.
  • Subjects must own a wearable pair of spectacles if required for their distance vision.
  • The subject must be an adapted soft contact lens wearer in both eyes (i.e. worn lenses a minimum of 2 days per week for at least 8 hours per wear day, for 1 month of more duration).

This may include, but not be limited to, diabetes, hyperthyroidism, Sjögren's syndrome, xerophthalmia, acne rosacea, Stevens-Johnson syndrome, and immunosuppressive diseases or any infectious diseases (e.g. hepatitis, tuberculosis).
  • Clinically significant (Grade 3 or 4) corneal edema, corneal vascularization, corneal staining, tarsal abnormalities or bulbar injection, or any other corneal or ocular abnormalities which would contraindicate contact lens wear.
  • Entropion, ectropion, extrusions, chalazia, recurrent styes, dry eye, glaucoma, history of recurrent corneal erosions.
  • Any previous, or planned, ocular or intraocular surgery (e.g. radial keratotomy, PRK, LASIK, lid procedures, dacryocystorhinostomy cataract surgery, retinal surgery, etc.).
  • A history of amblyopia, strabismus or binocular vision abnormality.
  • Any current ocular infection or inflammation.
  • Any current ocular abnormality that may interfere with contact lens wear.
  • Use of any of the following oral medications within 1 week prior to enrollment: oral retinoid isotretinoin (e.g. Accutane), oral tetracyclines, topical scopolamine, systemic steroids.
  • Use of any ocular medication, with the exception of rewetting drops.
  • History of herpetic keratitis.
  • Participation in any contact lens or lens care product clinical trial within 30 days prior to study enrollment.
  • Employee or immediate family member of an employee of clinical site (e.g., Investigator, Coordinator, Technician).
  • Any known hypersensitivity or allergic reaction to Optifree®Replenish® multipurpose care solution, sodium fluorescein or Eye-Cept® rewetting drop solution.
