senofilcon A	senofilcon A	Subjects that are of at least 60 years of age and non-habitual contact lens wearers will receive instructions to insert and remove a contact lens from each eye.

Primary Outcome Measures

Name	Time	Method
Overall Success Rate of Insertion and Removal of a Contact Lens	Lens insertion and Removal, up to 2-Hours	The subject attempted to insert a contact lens in each eye. The subject were allowed to voluntarily end the contact lens insertion activity at any time prior to the 20-minute time point. The time of insertion for each eye or the time of stopping the insertion process for each eye was recorded. Similarly, the time of removal for each lens or the time of stopping the removal process for each lens was recorded.
