Inclusion Criteria:

* Potential subjects must satisfy all of the criteria listed to be enrolled in the study.

  1. They are 18-45 years of age (inclusive).
  2. They understand their rights as a research subject and are willing and able to sign a Statement of Informed Consent.
  3. They are willing and able to follow the protocol.
  4. They agree not to participate in other clinical research while enrolled on this study.
  5. They currently use daily disposable soft daily wear contact lenses (worn bilaterally) (within the last six months) which may be spherical, toric or multifocal.
  6. They agree to wear their lenses for at least 12-14 hours per day.
  7. They own a wearable pair of spectacles (by self-report).
  8. They have a spherical contact lens prescription in the range +6.00 to -10.00 DS (based on the calculated ocular refraction).
  9. They have up to a maximum of 1.00 DC of refractive astigmatism (based on the calculated ocular refraction).
  10. They have best corrected distance visual acuity of at least 0.20 binocularly

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

  1. They have an ocular disorder which would normally contraindicate contact lens wear.
  2. They have a systemic disorder which would normally contraindicate contact lens wear.
  3. No ocular topical medications (including comfort drops) from 24 hours prior to study visits or during the wear of any study lenses.
  4. They are regularly using anti-inflammatory or pain medications (i.e. medication routinely used more than twice per week).
  5. They have had cataract surgery.
  6. They have had corneal refractive surgery.
  7. They are pregnant or breast-feeding.
  8. They have any infectious disease (e.g. hepatitis) or any immunosuppressive disease (e.g. HIV) or a history of anaphylaxis or severe allergic reactions.
  9. They are an employee or immediate family member of an employee of the clinical site (e.g. Investigator, Coordinator, Technician).
  10. They have taken part in any other clinical trial or research within two weeks prior to starting this study.
  11. History of allergy to sodium fluorescein or lissamine green.
  12. They have any corneal distortion e.g. as a result of previous rigid lens wear or have keratoconus.
  13. They any slit lamp findings of Efron Grade 3 or greater (e.g. corneal edema, corneal neovascularization, tarsal abnormalities, conjunctival injection) or findings of \< Grade 3 which in the investigator's opinion would contraindicate contact lens wear.
