disposing a contact lens sample in the well of the microfluidic chip;
disposing a volume of tear fluid in the well with the contact lens sample;
capturing tear images of the contact lens sample;
rinsing the contact lens sample;
capturing post-rinse images of the contact lens after the rinsing;
determining, using one or more of the tear images or the post-rinse images, a deposition metric; and
