Using ODyn

Running a Self-Experiment

Capture what happens when you change something — a supplement, a cut trigger — and see how your own data responds.

An experiment is how ODyn captures the diffuse signal of "I tried something and something changed." Start a supplement, cut out a suspected trigger, move to a new altitude — log it, and ODyn keeps the change tethered to your IOP and health data so you can see what actually shifted. It's observational tracking of your own data, not a clinical trial.

This guide covers logging an intervention, confirming a change ODyn detects, checking in, and reading your before/after.

Log an intervention

1. Open Experiments and choose Log an intervention. 2. Pick the type (started a supplement, cut a trigger, etc.), name it, and set the start date. 3. Optionally add what you're hoping to learn. 4. Save.

What to expect: it appears under "What you're tracking," and ODyn begins comparing your data before and after the start date.

Confirm a change ODyn detects

1. When ODyn notices an intervention-shaped change in your logged data — a new drop, a persistent altitude shift — it surfaces it as a candidate to review. 2. Tap Track it to keep it (or Add detail first), or Dismiss it.

What to expect: confirmed candidates become tracked experiments, just like ones you log yourself.

Check in

1. On a tracked experiment, tap how your vision feels — better, same, or worse. 2. Optionally add a note.

What to expect: your subjective read, tethered to the objective data so it never floats free.

See your before/after

1. Open an experiment. 2. Review the baseline-vs-active comparison — IOP and spike frequency — and your check-ins.

What to expect: an honest, observational look at what shifted. Treat it as a signal to discuss with your doctor, not proof of cause and effect.
