It is important that you look directly at the light as long as possible. It is also important that you do not keep your eyes closed all the time. That’s why we have developed the “eye-tracking” function, so that it can measure how much time you actually look directly at the screen.
Although the device is already equipped with eye tracking technology, this feature is only used in clinical trials to date. In the next software updates, ordinary users will also have access to and benefit from such data.
