5. Study Description

Brief Summary
The aim of this non-dispensing study is to evaluate the clinical performance of different hydrogel contact lens designs.
Detailed Description
This is a 35-subject, double masked, randomized, contra lateral, non-dispensing fitting trial comparing different hydrogel lens materials. For each study, this study will involve 2 visits: lens dispensing (baseline) and 1 hour post lens settling. Each subject will be randomized to wear the test and control lenses, in the right or left eye, in a series of four short fitting comparisons as follows: Pair 1 (P1): filcon IV I (Base Curve (BC) 8.6) and ocufilcon D Pair 2 (P2): filcon IV I (Base Curve (BC) 8.7) and ocufilcon D Pair 3 (P3): methafilcon A (Base Curve (BC) 8.6) and ocufilcon D Pair 4 (P4): methafilcon A (Base Curve (BC)8.7) and somofilcon A
