Earn $35/hr for helping us to conduct a non-invasive research on tear film thickness and dynamics.
We will simply acquire short videos of your eye that allow us to determine the film thickness from colorful interference patterns. Sessions will last approximately an hour, and you may participate in more than one session.
Ideal participants are experienced contact lens wearers, preferably using Oasys lenses, and have blue eyes.
