Descripción
Inclusion Criteria:
- The subject must read, understand, and sign the STATEMENT OF INFORMED CONSENT and receive a fully executed copy of the form.
- The subject must appear able and willing to adhere to the instruction set forth in this clinical protocol.
- The subject must be between 18 and 69 years of age.
- The subject must be willing to participate in a 9-month study.
- The subject must require a visual correction in both eyes.
- Subjective refraction must result in a vertex-corrected spherical contact lens prescription of +2.00D to -8.00D in each eye.
- The subject must have best-corrected visual acuity of 0.20 or better in each eye.
- The subject must be a current wearer of spherical soft contact lenses (no bifocal contact lenses or monovision) for at least 5 days/week and at least 8 hours/day during the month prior to enrollment.
- The subject must require no more than -1.25D cylindrical correction in each eye after vertexing to the corneal plane.
- The subject must have normal eye with no evidence of abnormality or disease that in the opinion of the investigator would contraindicate contact lens wear.
Exclusion Criteria:
- Self-reported current pregnancy or lactation or plans to become pregnant during the study period (subjects who report becoming pregnant during the study will be discontinued).
- Self-reported adverse reaction to a contact lens solution to be used in the study that in the opinion of the investigator would contraindicate use of that solution.
- Any previous ocular or intraocular surgery (e.g. radial keratotomy, PRK, LASIK, etc.).
- Any clinically meaningful slit lamp findings contraindicating contact lens wear (e.g. equal to or greater than Grade 3 finding of edema, corneal neovascularization, corneal staining, tarsal abnormalities, conjunctival injection, blepharitis/meibomian gland dysfunction) on the study specific classification scale or any other ocular abnormality that in the opinion of the investigator would contraindicate contact lens wear.
- Any active ocular infection.
- Current use of topical ophthalmic medications.
- History of binocular vision abnormality or strabismus.
- More than occasional use of dry eye/rewetting drops (more than 2 times per day on average).
- Any infectious disease (e.g. hepatitis, tuberculosis) or a contagious immunosuppressive disease (e.g. HIV) by self-report.
- History of severe allergic reaction or anaphylaxis.
- Other active ocular disease that in the opinion of the investigator would contraindicate contact lens wear.
- Employee of the investigational clinic (e.g. investigator, coordinator, technician)
- They have taken part in any other clinical trial or research, within two weeks prior to starting this study.

Overall Comfort Score (Senofilcon A Lens)
Periodo de tiempo: 2-Week Follow-up
|
CLUE overall comfort is assessed using the Contact Lens User Experience (CLUE)TM questionnaire for the senofilcon A lens only.
CLUE is a validated patient-reported outcomes questionnaire to assess patient experience attributes of soft, disposable contact lenses (comfort, vision, handling, and packaging) in a contact-lens wearing population in the US, ages 18-65.
Scores follow a normal distribution with a population average score of 60 (SD 20), where higher scores indicate a more favorable/positive response.
97% of the scores fall within 0 and 120 (mean +/-3XSD).
