Title: Dispensing Study to Assess the Visual Performance of Optimised Prototype Contact Lenses
Brief Summary: The aim of this study is to assess the visual performance of multiple optimised prototype soft contact lens designs compared to commercially available contact lenses.


Options:
A: Inclusion Criteria:

* Able to read and comprehend English and give informed consent as demonstrated by signing a record of informed consent.
* Be at least 18 years old, male or female.
* Willing to comply with the wearing and clinical trial visit schedule as directed by the Investigator.
* Have ocular health findings considered to be "normal" and which would not prevent the participant from safely wearing contact lenses.
* Is correctable to at least 6/12 (20/40) or better in each eye with contact lenses.
* Be suitable and willing to wear contact lenses.

Exclusion Criteria:

* Any pre-existing ocular irritation, injury or condition (including infection or disease) of the cornea, conjunctiva or eyelids that would preclude contact lens fitting and safe wearing of contact lenses.
* Any systemic disease that adversely affects ocular health e.g. diabetes, Graves disease, and auto immune diseases such as ankylosing spondylitis, multiple sclerosis, Sjogrens syndrome and systemic lupus erythematosus. Conditions such as systemic hypertension and arthritis do not automatically exclude prospective participants.
* Use of or a need for concurrent category S3 and above ocular medication at enrolment. Ocular medication can be prescribed during the course of the trial as per standard optometric practice.
* Use of or a need for any systemic medication or topical medications which may alter normal ocular findings / are known to affect a participant's ocular health / physiology or contact lens performance either in an adverse or beneficial manner at enrolment and/or during the clinical trial. Note: Systemic antihistamines are allowed on an "as needed basis", provided they are not used prophylactically during the trial and at least 24 hours before the clinical trial product is used.
* Eye surgery within 12 weeks immediately prior to enrolment for this trial.
* Previous corneal refractive surgery.
* Contraindications to contact lens wear.
* Known allergy or intolerance to ingredients in any of the clinical trial products.
B: Inclusion Criteria:

* Wearers of 1•DAY ACUVUE® TruEye™ or 1•DAY ACUVUE® MOIST® daily disposable soft contact lenses in both eyes aged \>8 years of age who have recently begun use of that lens type and have purchased at least 3 month supply of lenses.
* The registrant must read and sign the Informed Consent form. Minor subjects must obtain parental signature of Informed Consent and also sign an Informed Assent Form.
* The registrant must sign the Release of Medical Records in the event of an adverse event in the study.
* The registrant must appear able and willing to adhere to the instructions set forth in this clinical protocol.

Exclusion Criteria:

* Previously wearing the type of lenses with which they are registering (1•DAY ACUVUE® TruEye™ or 1•DAY ACUVUE® MOIST® Daily Disposable lenses).
* Current participant in an unrelated research study.
* Employee or family member of Recruiting Practitioner or Johnson \& Johnson.
C: Inclusion Criteria:

* The refractive error limited to ±5.00 spherical and ±0.75 cylindrical diopters
* Subjects with up-to-date optical prescription

Exclusion Criteria:

* Signs and symptoms of severe eye dryness or inflammation
* Substantial tear flow impairment
* Any systemic or ocular disorder known to compromise the ocular surface or tear film quality.
* At least two out of the following signs of dry eye disease:

  * Ocular Surface Disease Index higher or equal to 23,
  * Conjunctival staining higher or equal to 2 or/and corneal staining higher or equal to 2 (graded with Efron grading scale)
  * Fluorescein tear film break-up time shorter than 7 seconds.
D: Inclusion Criteria:

1. The patient must be at least 15 years old.
2. The patient must be free of any anterior segment disorders.
3. The patient must have a spectacle corrected spherical refractive error between +5.50 D and -11.00 D with less than or equal to 1.00 D refractive cylinder.
4. The patient must be correctable to 20/25 or better with spectacles.
5. Flat and steep corneal curvatures from Simulated Keratometry readings must be between 39.00 and 48.00 D.
6. Can be successfully fit with lotrafilcon A lenses at the enrollment visit.

Exclusion Criteria

1. The patient has worn rigid gas permeable lenses within the last 30 days or polymethylmethacrylate lenses within the last 3 months.
2. The patient must not be a current successful daily wear user of lotrafilcon A lenses. They may have tried lotrafilcon A lenses in the past, but must not have successfully worn these lenses for daily wear within the last 12 months.
3. The patient has an autoimmune disease (except for Hashimoto's Thyroiditis), immunocompromising disease, connective tissue disease, atopic dermatitis, insulin dependent diabetes, or any other systemic disease that in the investigator's opinion will affect ocular health.
4. The patient is taking chronic systemic medications such as corticosteroids, antimetabolites, or non-steroidal anti-inflammatory agents or any other medication that in the investigator's opinion will affect ocular physiology or study participation.
5. The patient has any ocular disease or condition such as aphakia, corneal dystrophies, corneal edema, external ocular infection, iritis, or had any anterior segment surgery.
6. The patient is taking any ocular medications. If a patient was previously taking any ocular medications, the medications must have been discontinued at least 2 weeks prior to enrollment.
7. The patient must have less than or equal to grade 2 on any of the slit lamp observations of: upper tarsal papilla, corneal staining, corneal neovascularization, conjunctival injection, and lid erythema or scales. Slit lamp findings higher than grade 2 bias the patient toward an adverse event and it may be difficult to detect true change related to contact lens use.
8. The patient is pregnant.
