Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective is to evaluate corneal staining observed after 2 hours of wear with contact lenses with investigational coating against PureVision™ lenses, all pre-cycled with OPTI-FREE® RepleniSH® multi-purpose disinfection solution.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this contralateral crossover study, qualifying subjects will wear a total of 2 pairs of study contact lenses. Lenses will be worn according to a randomized lens sequence assignment. Each pair will consist of a test lens (Test 1 or Test 2) and a control lens.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Able to understand and must sign an Informed Consent;
* Successful wearer of spherical soft contact lenses in both eyes for a minimum of 5 days per week and 8 hours per day during the past 3 months;
* Manifest cylinder less than or equal to 1.50 diopter (D) in each eye;
* Best Corrected Visual Acuity (BCVA) 20/25 or better in each eye;
* VA with habitual spectacles 20/40 in both eyes (OU) or better and willing to wear spectacles as needed during the washout period and during study lens exposure;

Exclusion Criteria

* Any anterior segment infection, inflammation, abnormality or disease that contraindicates contact lens wear;
* Any use of systemic or ocular medications for which contact lens wear could be contraindicated;
* History of refractive surgery or plan to have refractive surgery during the study or irregular cornea in either eye;
* Ocular or intra-ocular surgery (excluding placement of punctal plugs) within the previous 12 months or planned during the study;
* Current or history of pathologically dry eye in either eye that would preclude contact lens wear;
* Current or history of herpetic keratitis in either eye;
* Eye injury in either eye within 12 weeks immediately prior to enrollment;
* History of intolerance or hypersensitivity to any component of the study lenses or solutions;
* Habitual contact lenses worn in an extended wear modality (routinely sleeping in lenses for at least 1 night per week) over the last 3 months prior to enrollment;
* Use of topical ocular medications and artificial tear or rewetting drops that would require instillation during contact lens wear;
