Introduction
Please read the following introduction from Dr. Terrance Waggoner, the creator
of "The Color Vision
Testing Made Easy" product.
Several years ago my son T.J., who was six years old at the time, came home
from school with a note from the school nurse saying he was "colorblind".
Being an Optometrist, I should have already known he had a color deficiency.
I thought back to when T.J. was in pre-school and kindergarten. His teachers
mentioned he was having difficulty learning concepts such as grouping same
or different colored objects. I thought it was a learning problem. I did
not think it could be a visual problem because at age 4, before he started
pre-school, I had a pediatric eye doctor who was a friend of mine give T.J.
a complete eye examination.
I told my friend
about the note from the school nurse. She confided that she didn't test
the color vision of pre-school children because of time restraints and the
difficulty of testing such a young age group. This is the case with most
vision care professionals, and why I developed "Color
Vision Testing Made Easy".
Product Overview
and Description
"Color Vision Testing Made Easy" uses simple objects and symbols
making color vision testing fun, quick and easy for all age groups, including
preschool children. It contains 14 different cards and takes only a minute
to administer and score - making it invaluable for large vision screenings.
The test is divided into two parts. Part I has simple symbols (circle, star,
square) to test the color vision of the general public. These cards feature
two objects, so a color deficient person can see one of the objects. This
way he or she sees something and does not get discouraged or self-conscious.
It also validates that the person understands the test and is trying their
best.
Part II has objects such as a dog, balloon and boat turning color vision
testing into a fun game of matching or tracing for young children, as well
as individuals with learning disabilities or those who are non-communicative.
Product
Use and Procedure
The purpose of "Color Vision Testing Made Easy" is to detect subjects
who are color deficient. The test cards should be held at 30 inches and
at right angels to the subject's line of sight. Use the same light sources
recommended for all pseudoisochromatic color vision tests like the Ishihara.
If the subject correctly identifies the circle, star, or square on 8 of
the first 9 test cards they pass. You are then done testing and can record
normal color vision. Even color deficient subjects should correctly
identify one object on the first six cards. This test checks for malingering
and confirms the subject understood the test instructions.
|
The test has optional instructions
and scoring for children as young as 3 and special needs students. Simply
ask them to find or show you the ball (circle) on cards 1-9. If they find
8 of 9 balls (there is one ball on all nine test cards), they pass. If they
find less than 8 balls, they fail. Every subject should find one ball on
cards 1,3, and 5, if not, they do not understand the instructions or are
malingering. This technique is successfully used to test the color vision
of World Special Olympic Athletes worldwide.

Frequently
Asked Questions About Colorblindness, answered by Dr. Terrace L. Waggoner
| Q: |
I
am a concerned parent and have a question that hopefully you can help
me with. My son is four years old and was diagnosed as being color
deficient. We believe my father might have the same problem, but has
never been tested. The doctor performed a color test on my son with
the numbers. My four year old is not very good with his numbers and
when the doctor would ask what numbers he could see, my son couldn't
tell her because he either didn't know them or actually could not
see them. When she showed him the trails from x to x, he was not able
to follow the trails. When she saw that he could not follow the trails
nor reply with the numbers she diagnosed him as being partially colorblind.
He has a tendency of seeing everything blue. Is there a possibility
that she could have misdiagnosed him because of the fact that he simply
did not know his numbers? |
| A: |
It is "most"
likely your son is color deficient. Blue is one of the colors that
color deficient subjects recognize. It is less likely that your son
did not understand the test, but I do understand your concern. When
there is a "nil" response, it is hard to be confident in
a diagnosis. Color Vision Testing Made Easy was designed to help with
this problem. The first six cards have two objects, either a circle,
star, and/or square. Children do not need to know their numbers. A
color deficient person will see one object and a color normal person
will see two objects. This way the color deficient person identifies
something letting you know they understand the test and are trying
their best. You normally feel confident in your diagnosis. I tested
my youngest son at age 2 using Color Vision Testing Made Easy by him
simply finding a ball (circle) on eight of nine test cards.
Early diagnosis is important. Have your son re-tested before he starts
pre-school. Also, check more of the family history. If grandfather
or any uncles, cousins, etc. are color deficient, this will support
your diagnosis.

| Q: |
I
think my 3-year-old son cannot distinguish red and green accurately.
Everyone I have tried refuses or are unable to test children unless
they know their numbers. |
| A: |
Look at my web page
"What
teachers, school nurses, and parents, should know about being colorblind."
The web page identifies some of the common "confusion colors".
Armed with this information, ask your son what color some of his favorite
toys are e.g. what color is Barney? Purple is sometimes confused with
blue. I recommend testing your son using Color Vision Testing Made
Easy. With this color vision test children do not need to know their
numbers

Evaluation of
a new Color Vision Test: "Color Vision Testing Made Easy"
Summary of Journal American Academy of Optometry, vol. 76, no. 9, Sept.
1999 article.
By Susan A. Cotter, O.D., David Y. Lee, O.D., Ph.D.,
Alan L. French, B.A.
Susan Cotter, O.D. (Pediatric Specialist, Southern CA College of Optometry)
and David Lee, Ph.D., O.D. (Color Vision Specialist, Illinois College of
Optometry) completed a validation study of Color Vision Testing Made Easy.
They proved it was a valid color vision test and 100% Ishihara compatible.
Testability of kindergarten children was 100% with no false positives.
"Testability of a Color Vision Screening Test in a Population with
Mental Retardation"
Summary of the Journal of the American Optometric Association Vol. 70, #12,
Dec. 1999 article.
By Graham B. Erickson, O.D., F.A.A.O., F.C.O.V.D.
and Sandra S. Block, O.D., F.A.A.O.
Color Vision Testing Made Easy was also used in a special study by Graham
Erickson, O.D. (Pacific University College of Optometry) and Sandra Block,
O.D. (Illinois College of Optometry) to test the color vision of Special
Olympic Athletes in the 1997 World Winter Games in Toronto, Canada; the
Regional European Swim Competition in Spain; and the Summer Games in Texas
and Massachusetts, USA. They demonstrated the new color vision test, because
of its simplicity, could be used to detect color deficiencies in mentally
handicapped patients. The American Optometric Association Sports Vision
Section and Special Olympic International sponsored the study.

Testimonials
I would like
to inform you that we were able to test several questionable children for
colorblindness verses cognitive limitation during this school year. All
the children were between 3-4 years of age and we had no problems in administering
the test and were confident with the results. Thank you for developing this
wonderful product/diagnostic tool.
