How it works

  1. Choose a condition

    Search above or pick one from the list. Start with the normal exam to see what healthy eyes do.

  2. Use a clinical tool

    Shine the penlight, cover an eye or hold up a prism — the eyes respond like a real patient’s.

  3. Understand the finding

    Open the clinical deep-dive under the eyes to learn what the sign means and why it happens.
