Each day, when you open the OdySight app, a new visual test will be required before you can proceed to play the puzzle game. Once this test is done, and if you already used the application at least twice, you will be able to do more tests, with a limit of one test per type of test, per eye and per day.
To test your second eye:
Open your app and use your password.
Once in the app, click on the eye at the bottom right of the screen to display the list of tests.
Click on the test you want to do and choose which eye you want to test.
You should then be able to watch the instructions and start your visual test.
