Can I change the therapy mode?

Yes; You can switch the therapy type in the Therapy Settings within the Parent Menu. If you want to switch from Monocular Training to Binocular Training, you will first have to undergo the Binocularity Assessment. Only if you are able to pass this assessment, will you be granted an upgrade to Binocular Training. There are no limitations on switching from Binocular Training to Monocular training.
