To stimulate the muscles of the eyes, the player trains in three different levels. For this purpose, he uses a so-called vision stick. However, any other stick with letters on it will also work.

The player focuses on one letter on the stick. From this position, the player now turns the head first to the right in 3 directions: obliquely upwards, horizontally to the center and obliquely downwards.

He then performs the exercise on the left side.

The following variations are possible: top left to bottom right; top right to bottom left. On the horizontal plane, the speed can also be increased.
