Can your phone detect double vision? new study puts app to the test
NCT ID NCT07571538
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study checks how accurate and repeatable a smartphone app called VisionApp is at measuring ghosting (a type of double vision). Twelve healthy adults will wear contact lenses and rate ghosting images while the app also measures it. The goal is to see if the app can reliably replace clinic-based tests.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- VisionApp smartphone app
- 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.
