NCT02388763

Brief Summary

The purpose of this study is to evaluate the functional vision of 2 daily disposable silicone hydrogel contact lenses using Time Controlled Visual Acuity (TCVA) measurements at high luminance and high contrast after 10+/-3 days of wear post 3 hour exposure to a reduced humidity environment.

Outcome Measures

Primary Outcomes (1)

  • High Contrast Time-Controlled Visual Acuity (TCVA) (VA Unit) Post-Exposure to Reduced Humidity at Day 10

    High contrast TCVA was assessed after 3 hours exposure to reduced humidity environment. TCVA test was performed at 4 meters under high illumination (90%) using a Landolt ring test. For each acuity level, a series of single rings with gaps in one of four directions was presented and the percentage of correctly identified rings constituted the score. TCVA was measured in VA units and a higher TCVA value indicates an improvement in visual acuity. Both eyes contributed to the analysis.
