The study lenses will be worn in a bilateral and random fashion using a 5x5 crossover Williams design with 5 lens types and 5 periods. The subjects will wear each pair of lenses for approximately 15 minutes with a 15 minute wash-out between each pair. Two lens types will be fit at the first visit and three lens types will be fit at the second visit. Using a computer-generated randomization scheme, each subject will randomly be assigned to 1 of 10 unique sequences of the 5 lens types. Randomization will be stratified by site.
