Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* The subject must respond positively to at least one symptom on the "Presbyopic Symptoms Questionnaire" or be already wearing presbyopic contact lens correction ( e.g. reading spectacles over contact lenses, multifocal or monovision contact lenses etc.).
* The subject's spherical equivalent distance refraction must be in the range of -1.00 to -6.00 in each eye.
* Refractive cylinder must be less than or equal to -0.75 D in each eye.
* The subject must have an add power of +0.75D to +2.50D in each eye.
* The subject must have best corrected visual acuity of 20/20-3 or better in each eye.
* The subject's must have at least 20/30-distance vision with the study contact lenses.
* The subject must agree that they are comfortable with their vision prior to being dispensed the study lenses.
* The subject must be an adapted soft contact lens wearer in both eyes.
* The subject must appear able and willing to adhere to the instructions set forth in this clinical protocol.
* The subject must read and sign the STATEMENT OF INFORMED CONSENT and be provided a copy of the form.
Exclusion Criteria
* Systemic disease, autoimmune disease or use of medication, which may interfere with contact lens wear.
* Clinically significant (grade 3 or 4) corneal edema, corneal vascularization, corneal staining or any other abnormality of the cornea, which may contraindicate contact lens wear.
* Clinically significant (grade 3 or 4) tarsal abnormalities that might interfere with contact lens wear.
* Any ocular infection.
