What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to
If successful, this app could provide a simple, at-home way to measure ghosting vision, helping eye doctors diagnose and monitor double vision more easily.
What could go wrong
This is a very small, early study with only 12 healthy participants, so results may not apply to people with eye diseases. The app's accuracy in real-world settings is still unproven.
