Query: The Stanford Acuity Test: A Precise Vision Test Using Bayesian
  Techniques and a Discovery in Human Visual Response   Chart-based visual acuity measurements are used by billions of people to
diagnose and guide treatment of vision impairment. However, the ubiquitous eye
exam has no mechanism for reasoning about uncertainty and as such, suffers from
a well-documented reproducibility problem. In this paper we make two core
contributions. First, we uncover a new parametric probabilistic model of visual
acuity response based on detailed measurements of patients with eye disease.
Then, we present an adaptive, digital eye exam using modern artificial
intelligence techniques which substantially reduces acuity exam error over
existing approaches, while also introducing the novel ability to model its own
uncertainty and incorporate prior beliefs. Using standard evaluation metrics,
we estimate a 74% reduction in prediction error compared to the ubiquitous
chart-based eye exam and up to 67% reduction compared to the previous best
digital exam. For patients with eye disease, the novel ability to finely
measure acuity from home could be a crucial part in early diagnosis. We provide
a web implementation of our algorithm for anyone in the world to use. The
insights in this paper also provide interesting implications for the field of
psychometric Item Response Theory.
