Primary Outcome Measures:
  • Percentage of Participants With Contact Lens Distance Visual Acuity Change From Baseline [ Time Frame: Baseline, Day 90 ]
    Contact lens distance visual acuity was measured for each eye using the LogMAR visual acuity eye chart. The worse eye at Baseline was used for analysis. A change of 0.1 on the LogMAR scale was equivalent to a 1 line change in visual acuity. The following categories are reported: Better=an increase in 2 or more lines, No Change=a change of +/- 1 line, and Worse=a decrease of 2 lines or more.


Other Outcome Measures:
  • Average Daily Contact Wearing Time [ Time Frame: Day 90 ]
    The average reported number of hours per day that contact lenses were worn by participants during the previous 7 days.

  • Reason for Contact Lens Replacement [ Time Frame: Day 90 ]
    The reason the contact lens needed to be replaced was recorded for each eye. The following categories are reported: Scheduled Replacement, Discomfort, Lens Damage, Unacceptable Vision and Lens Lost. There may be multiple reasons for replacement of the contact lens for a single eye.

Arms Assigned Interventions
Experimental: Carboxymethylcellulose Based Eye Drop Formula
1-2 drops of carboxymethylcellulose based eye drop formula in each eye, a minimum of 4 times a day for 90 days. One of the 4 times a day may be to prepare the contact lens for insertion.
Drug: carboxymethylcellulose based eye drop formula
1-2 drops of carboxymethylcellulose based eye drop formula in each eye, a minimum of 4 times a day for 90 days. One of the 4 times a day may be to prepare the contact lens for insertion.
Active Comparator: REFRESH CONTACTS®
1-2 drops carboxymethylcellulose sodium based eye drop solution (REFRESH CONTACTS®) in each eye, a minimum of 4 times a day for 90 days. One of the 4 times a day may be to prepare the contact lens for insertion.
Drug: carboxymethylcellulose sodium based eye drop solution
1-2 drops carboxymethylcellulose sodium based eye drop solution (REFRESH CONTACTS®) in each eye, a minimum of 4 times a day for 90 days. One of the 4 times a day may be to prepare the contact lens for insertion.
Other Name: REFRESH CONTACTS®
