The OdySight algorithm determines which eye will be tested each day, which test should be done and how often the eye will be tested. When you open your app, it will tell you that an eye test needs to be done.
To do this test:
Open the app and use your password.
Once in the app, click on the red exclamation mark at the bottom right of the screen to display the list of visual tests.
Start the imposed test, displayed in red.
If you wear glasses, put them on. Then follow the instructions to keep your head at the right distance from the screen.
Hide your non-tested eye as shown in the app then click on Start test.
Once the test is finished, you will be redirected to the main page of the application. You should then be able to start another visual test.
