"What is myVisionTrackX (mVTx)?
The mVTx application supports people living with eye conditions and their eyecare professionals. The app features are customized to the particular user, thereby enabling a personalized user experience.

mVTx is for use by the study participant to whom the application was prescribed as part of a clinical trial. If someone else completes any of the activities in your place, it could make your results inaccurate.

What happens if you post a user review on the app store?
If you post a user review, please note that your feedback will be shared with the study sponsor to decide if a safety report should be made to a regulatory authority in the USA, the UK, or any other country."
