  6. The subject's refractive cylinder must be 1.00 D or less in each eye.
  7. Have a spherocylindrical best corrected visual acuity of 20/30 or better in each eye (Snellen Visual Acuity).

     Exclusion Criteria:
* Potential subjects who meet any of the following criteria will be excluded from participating in the study:

  1. Currently pregnant or lactating.
  2. Any systemic disease (e.g., Sjögren's Syndrome), allergies, infectious disease (e.g., hepatitis, tuberculosis), contagious immunosuppressive diseases (e.g., HIV), autoimmune disease (e.g. rheumatoid arthritis), or other diseases, by self-report, which are known to interfere with contact lens wear and/or participation in the study.
  3. Use of systemic medications (e.g., chronic steroid use) that are known to interfere with contact lens wear.
  4. Any ocular allergies, infections or other ocular abnormalities that are known to interfere with contact lens wear and/or participation in the study. This may include, but not be limited to entropion, ectropion, extrusions, chalazia, recurrent styes, glaucoma, history of recurrent corneal erosions, aphakia, or corneal distortion.
  5. Any corneal distortion resulting from previous hard or rigid gas permeable contact lens wear, history of strabismus, or current monovision, multi-focal, or toric contact lens correction.
  6. Any current use of rewetting drops or ocular medication.
  7. Any previous, or planned (during the course of the study) ocular surgery (e.g., radial keratotomy, PRK, LASIK, etc.).
  8. Any grade 3 or greater slit lamp findings (e.g., edema, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival injection) on the FDA Biomicroscopy Scale.
  9. Any previous history or signs of a contact lens-related corneal inflammatory event (e.g., past peripheral ulcer or round peripheral scar), or any other ocular abnormality that would contraindicate contact lens wear.
  10. Any known hypersensitivity or allergic reaction to ketotifen.
  11. Participation in any eye drop, contact lens or lens care product clinical trial within 14 days prior to study enrollment.
  12. Employee or immediate family member of an employee of clinical site (e.g., Investigator, Coordinator, Technician).
