Approximately 20 habitual soft contact lens wearing participants will be enrolled in this unilateral, randomized, double-masked (participant and investigator masked) repeated measures insertion study. All participants will be seen for a Screening/Dispensing Visit at which informed consent will be obtained and eligibility will be assessed. If participants satisfy all eligibility criteria and none of the exclusion criteria, subjects will insert study lenses in random, successive order according to unique randomization schedules that will be provided to each Investigator.

Surface Refractive Index Shifts at 5 Minutes
Refractive index is the ratio of velocity of light in a material divided with velocity of light in vacuum. The eye was measured for surface refractive index on the refractometer. The refractive index of a medium is the ratio of the speed of light in vacuum to the speed of light in the medium. It has no units.
Time frame: 5 minutes
