Search above or pick one from the list. Start with the normal exam to see what healthy eyes do.
Shine the penlight, cover an eye or hold up a prism — the eyes respond like a real patient’s.
Open the clinical deep-dive under the eyes to learn what the sign means and why it happens.
Step-by-step guides to each exam technique. Every guide opens the matching case on the simulator.
For educational purposes only — not for clinical diagnosis.
