Eligibility Criteria
You may qualify if:
- The subject must be at least 18 and less than or equal to 39 years of age and have a need for vision correction in both eyes.
- The subject must require a lens power between -1.00 to -6.00D and have no more than 1.00D of corneal cylinder.
- The subject, based on his/her knowledge, must be in good general health.
- The subject must be able and willing to adhere to the instructions set forth in this protocol and complete all specified evaluations.
- Subject must be a current adapted daily wearer of soft contact lenses with at least 6 months of CL wear.
- Subject must agree to wear their contact lenses in both eyes on a daily wear schedule for at least 8 hours per day every day during the study.
- Subject must be willing and able to use only the care systems and lubricating drops provided for the study during the 4 week period.
- The subject must read, indicate understanding of and sign the Informed Consent Form.
You may not qualify if:
- The subject is a rigid gas permeable (RGP) or daily disposable lens wearer.
- The presence of clinically significant (grade 3 or 4) anterior segment abnormalities; inflammations such as iritis; or any infection of the eye, lids or associated structures.
- The presence of ocular or systemic disease or need for medication which might interfere with contact lens wear or which would cause the lenses to be removed more than twice a day. (i.e., Sjogren's syndrome, type II diabetes, etc.)
- Slit lamp findings that would contraindicate contact lens wear such as:
- pathological dry eye or associated findings
- pterygium or corneal scars within the visual axis
- neovascularization equal to or greater than 1mm in from the limbus
- history of giant papillary conjunctivitis (GPC) worse than grade 2
- anterior uveitis or iritis (past or present)
- seborrhoeic eczema
- seborrhoeic conjunctivitis
- A history of recurrent erosions, corneal infiltrates, corneal ulcer or fungal infections.
- A known history of corneal hypoesthesia (reduced corneal sensitivity).
- Contact lens snellen visual acuities (VA) worse than 20/30.
- Aphakia, keratoconus or a highly irregular cornea.
