The OPI 2.0 System false positive and false negative errors and verification of the software analysis. Image of (A) low density, low dispersion, and low brightness; (B) high density, low dispersion, and high brightness; and (C) high density, high dispersion, and high brightness, with designated artificial eye on the left and OPI 2.0 System output with the areas of detected simulated tear film breakup in red on the right.

Note: ^aThe OPI 2.0 System false positive and false negative errors were dependent on the given parameters.
