1. Hold the cards against the bridge of nose so that the letter “A” is the closest to the nose.

2. Hold closely the cards 40 cm from your eyes.

3. Try to focus the air before the cards and cross the images. (If it isn’t succed you can use an aid eg.: a pointer or a pencil).



4. If everything is succed you should be seen 3 cards. Focus the middle of the cards and listen that the inner circles shifts to compensate each other.

5. Try to read the word in the middle of the smaller circel clearly.

The exercise can be easier or more difficult eg.: with the pointer.
