What is it about?

Pupillometry is the measurement of pupils and it is easily done with expensive equipment. Cheap devices or smartphones can measure light colored irises, yet dark irises are more challenging. We build on previous work to use a red light filter to capture the dark colored irises in addition to light colored ones. This work proposes a user-assembled, cheap interface to facilitate these measurements with the filter, thereby enabling accessible and fair pupillometry measurements.
