Abstract:
Disclosed herein are methods for quantifying contact lens deposition. An example method may comprise disposing a contact lens sample in a fluid well. The example method may comprise disposing a volume of tear fluid in the well with the contact lens sample. The example method may comprise capturing pre-rinse images of the contact lens sample. The example method may comprise rinsing the contact lens sample. The example method may comprise capturing post-rinse images of the contact lens after the rinsing. The example method may comprise determining, using one or more of the tear images or the post-rinse images, a deposition metric. The example method may comprise outputting the deposition metric.
