Brief summary

The aim of the study is to evaluate if the performance of Invigor A is substantially equivalent to Invigor B contact lenses when used in a one month recommended replacement, daily wear modality.

Detailed description

This study is a multi-centered, daily wear, monthly replacement, bilateral, randomized in a ratio of two to one (2:1) Test to Control, lens blocked (subjects remain in the same lens brand throughout the study), licensed investigator and subject masked, concurrent controlled study with a study duration of approximately three months evaluating performance equivalence of Invigor A (test) over Invigor B (control) contact lenses.

Masking description

The subject will know the name of the lens however they will not be aware of which lens is investigational and which lens has been previously cleared. The licensed investigator has not been informed which lens is the investigational lens.

Inclusion criteria

* Inclusion Criteria: 1. Be at least 18 years of age as of the date of evaluation for the study 2. Have 1. Read the informed consent document 2. Been given an explanation of the informed consent document 3. indicated understanding of the informed consent document 4. Signed the informed consent document 3. Be willing and able to adhere to the instructions provided by the investigational site and be willing to keep all specified appointments. 4. Be an adapted, frequent replacement, current full - time silicone hydrogel or soft contact lens wearer. An adapted full- time wearer is defined as wearing contact lenses at least 5 days per week for at least 8 hours per day for at least one month prior to participation in the study. 5. Possess or obtain prior to dispensing, wearable and visually functional (20/40 or better) eyeglasses. 6. Be in good general health, based on his/her knowledge. *

Exclusion criteria

1. Wearing lenses in a monovision modality and is unwilling to be fit with distance lenses in both eyes for the duration of the study. Note: Subjects may not wear lenses in a monovision modality at any time during the study as it will interfere with the visual acuity analysis. 2. Poor personal hygiene. 3. Any active participation in another clinical trial during this trial or within 30 days prior to this study. 4. To the best of the subject's knowledge, she is currently pregnant, is lactating or is planning a pregnancy within the next 3 months. 5. A member, relative or household member of the investigator(s) or of the investigational office staff. 6. A known sensitivity to the ingredients used in the multi-purpose solution approved for use in the study and is unable or unwilling to use the alternate care system. 7. Had previous refractive surgery; or current or previous orthokeratology treatment. 8. Aphakic or pseudophakic. 9. Ocular or systemic disease such as, but not limited to: anterior uveitis or iritis (past or present), glaucoma, Sjögren's syndrome, lupus erythematosus, scleroderma, keratoconus or uncontrolled diabetes. 10. The need for topical ocular medications or any systemic medication which might interfere with contact lens wear or require the lenses to be removed during the day. 11. A known history of corneal hypoesthesia (reduced corneal sensitivity), corneal ulcer, corneal infiltrates, iritis, bacterial or fungal infections. 12. A history of papillary conjunctivitis that has interfered with contact lens wear.
