Brief summary
The objective of this study is to determine the product feasibility of the investigational contact lens (Test) when compared to the currently marketed Acuvue Oasys contact lens (Control) and the Air Optix Aqua contact lens (Control) when worn by adapted wearers of soft contact lenses.
Interventions
After one week of wearing the first lens type, the participants will crossover to the second lens type for one week, and then crossover to the third lens type.
After one week of wearing the first lens type, the participants will crossover to the second lens type for one week, and then crossover to the third lens type.

Eligibility
Inclusion criteria
* Participants must have clear central corneas and be free of any anterior segment disorders. * Participants must be adapted wearers of soft contact lenses, wear a lens in each eye, and each lens must be of the same manufacture and brand. * Participants must be myopic and require lens correction from -0.75 D to - 4.75D in each eye.
Exclusion criteria
* Participants who have worn gas permeable (GP) contact lenses within the last 30 days or who have worn polymethylmethacrylate (PMMA) lenses within the last three months. * Participants with any systemic disease affecting ocular health. * Participants using any systemic or topical medications that will, in the Investigator's opinion, affect ocular physiology or lens performance. * Participants with an active ocular disease or are using any ocular medication. * Participants who have had any corneal surgery (eg, refractive surgery). * Participants who are allergic to any component in the study care products.

Participant flow
Recruitment details
There were 120 participants enrolled in this bilateral eye, three-period crossover study at four investigative sites in the United States (US). All participants were adapted wearers of soft contact lenses. The first participant was enrolled in the study on 5/10/2010 and the last participant exited the study on 6/10/2010.
Pre-assignment details
Participants were equally randomized to one of six treatment sequences of the investigational RD2106 contact lens (Test), the Air Optix Aqua contact lens, and the Acuvue Oasys contact lens. Of the 120 participants enrolled 2 were ineligible at baseline and 2 discontinued following dispensing of lenses. 116 participants completed the study.
