Anaglyphic Tasks
{THIS THERAPY TECHNIQUE IS BEST FOR TREATING SUPPRESSION WHEN
MINIMAL INEXPENSIVE EQUIPMENT IS DESIRED. ALTHOUGH IT WILL WORK
WHEN PATIENTS ARE ABOVE AGE FOUR IT IS BEST IF THE PATIENT IS
OVER AGE SEVEN.}
PATIENT INSTRUCTIONS
Anaglyphic Tasks
The purpose of this therapy is to increase the ability to maintain single,
clear, comfortable binocular vision through elimination of suppression. An
additional goal is to train convergence and divergence. You will know you are
doing the techniques correctly when you can do the procedures smoothly and
accurately without suppression.
Perform therapy _________ minutes daily and increase the number of procedures
in each session as you do them. In the beginning you may experience
discomfort such as headaches, eye strain, etc., and have to limit the therapy
to a few minutes. As your ability improves, your discomfort will disappear
and the therapy time can be increased. Remember that therapy fifteen minutes
daily is better than therapy two hours once a week. It would be best if you
do this therapy at __________ each day. Try to establish a routine so that
you always do the techniques at the same time each day.
Set Up:
Put the red-green glasses on (over your glasses if you wear
them) with the red lens over the _________ eye. Place a page from the
coloring book onto the sheet of white paper.
Correct Response:
The task in this therapy is to use a red marker (a
crayon, colored pencil/pen, or felt tipped marker) to trace or write on a
white piece or paper. In order for you to do this correctly you must be able
to see both the red marks that you make and the black marks at the same time.
Note that only the green-filtered (suppressing eye) can see the red marks. If
the red marks disappear you are suppressing that eye. You must try to break
suppression by blinking your eyes, jiggling the tip of the marker or by using
a marker with a wider tip.
Procedure 1:
Using the red-green glasses with the red lens over the
_________ eye, take the red marker and trace over the outline of one of the
pictures in a coloring book. Make sure that you can see the tip of the
marker, the lines that you are making and the outline of the picture all at
the same time. Do not trace unless you can see your lines, the tip of the
marker and the outline of the picture at the same time. Each time that you
notice suppression, make a slash through the outline and then try to break
suppression by blinking or moving the marker.
Procedure 2:
Using the red-green glasses with the red lens over the
_________ eye, take the red marker and do a dot-to-dot game. Make sure that
you can see the tip of the marker, the lines that you are making and the dots
all at the same time. Do not connect any dots less you can see your lines,
the tip of the marker and the outline of the picture at the same time. Each
time that you notice suppression, make a slash through the outline and then
try to break suppression by blinking or moving the marker.
Procedure 3:
Using the red-green glasses with the red lens over the
_________ eye, take the red marker and play tic-tac-toe using black lines for
the game grid. Make sure that you can see the tip of the marker, the X's and
O's that you are making and the game grid all at the same time. Do not make a
mark unless you can see your marks, the tip of the marker and the game grid at
the same time. Each time that you notice suppression, make a slash through
the outline and then try to break suppression by blinking or moving the
marker.
Procedure 4:
Repeat the above task using other "games" for anti-
suppression tasks. Some possibilities are Hang-man, cross word puzzles,
Battleship, and Pyramid. Checkers can also be played using a red and black
board and red- green glasses.
Do this for _______ minutes every day. As you improve you can make the task
more difficult by using a thinner crayon or a red pencil with a thin lead.
Write down any observations or questions that you have. Save your completed
tracings and show them to your clinician.
