How fast can your eyes change focus?
Langemo Vision is building a phone-based test that measures how quickly the eyes shift between near and far targets, for athletes, teams, and eye care professionals.

Our test uses two ordinary phones: one held at reading distance and one placed ten feet away. Landolt ring targets alternate between them, and the athlete answers each one as fast as possible. The app times every shift, near to far and far to near, separately.
Each phone calibrates its distance with the camera, and target sizes are matched so the near and far tasks are equally demanding.
Our test is in research and development and is not yet available.
