My son with autism complained of frequent headaches, squinted, and showed difficulty reading. His pediatrician recommended an evaluation by an eye doctor. We anxiously awaited the appointment with the ophthalmologist and felt we would get answers. It was a surprise that James’ vision was ‘normal.’ He was seeing a perfect 20/20 for distances both near and far (perfect visual acuity). We left with no answers about the problems James was having. I’m guessing many of you have had similar experiences.
Our story is not unusual. Many children who have autism experience
difficulties with copying from the board, coordinating eyes with hands,
frequent headaches after completing class and homework. Vision concerns manifest themselves in many
ways. All children are required to have
regular vision screenings which test for structural defects and deficits in
eyesight. When we think of an eye exam,
we picture the chart with letters of decreasing sizes. (FYI, it’s called the
Snellen chart and was invented in the early 1860s.) While it is important that we ‘see’ the information
properly, how we extract meaning and understanding of what we see requires
further testing. Our brains devote a
huge amount of space for visual processing.
There are many more parts of the brain involved in vision and making
sense of what we see. When we see
colors, light, movement, and distance.
According to DiscoverMagazine.com, “in the brain itself, neurons devoted
to visual processing number in the hundreds of millions and take up about thirty
percent of the cortex, as compared with eight percent for touch and just three
percent for hearing.”
Developmental
optometrists specialize in the neurological process of vision and are specially
trained to evaluate functional vision skills such as peripheral vision,
focusing eyes in near and far, color perception, and fine and gross visual-motor
coordination. So, a visual screening
which is routinely done in school looks at the eye structure and ability to see
near and far, a functional visual evaluation focuses on how the eyes work
together and if there is a developmental problem with the eyes as they move
together. Visual figure-ground is when
the eye can choose what’s important out of competing visual information. We’ve all asked our children to get an item
out of the refrigerator, only to hear, ‘mom, it’s not in there.’ Children often
don’t take the time to scan and identify the refrigerator for the item they
need. The popular book series, “Where’s
Waldo” is an excellent example of exercises designed to work on honing visual
discrimination information.

Here are a few examples of
eye problems and how to help at home. In
my books, I call them ‘Out of the POCKET
Activities.’
What is visual discrimination?
Recognizing letters and numbers is critical for math and reading
skills. Not only does the eye ‘see’ the
information on the page, the viewer must make sense of, or interpret the
information. If a child is not able to
discriminate between what he sees, he might reverse letters and numbers well
beyond the time in which it’s appropriate to do so. Additionally, he may experience difficulty
recognizing social cues and non-verbal communications with peers.
What can you do to help your child today?
·
Minimize glare and artificial or fluorescent
lighting.
·
Use a cardboard or cardstock sheet and cut a
‘window’ out. This will minimize competing
objects on the paper.
·
Practice
by doing word searches. They help the
eyes to scan for important information.
·
Cut
out small newspaper clippings and ask your child to circle a specific letter
each time she sees it. So, every time
she sees a letter a, she circles it in red pen.
·
Move
her homework space to a less distracting area of the home.
I was recently trained as a certified Irlen screener. Until recently, Irlen syndrome was not on my
professional radar. Helen Irlen found
that many people have difficulties processing visual information in the
brain. Some of the symptoms are eye
strain, headaches, difficulty with reading comprehension, and poor
depth-perception. Of course, anytime a
child struggles with vision or has weaknesses, his self-esteem may be
impacted. Irlen syndrome causes a sensitivity
to different types of lighting.
Sensitivity to fluorescent lighting, sunlight, or glare are common
complaints of someone suffering with Irlen Syndrome. To help make life more comfortable, special
colored overlays or even filtered glasses are prescribed for optimal comfort. Results may be amazing! For more information, visit
www.Irlen.com. There’s a self-test and
the screen even changes colors while on the site in order for the reader to try
out how color affects reading while on the site.
Here are some tips you can try today
for light sensitivity:
·
Print
worksheets and homework on pastel paper.
This is commonly found in office supply stores. Try copying the same worksheet on each of the
colored papers in order to determine which color you/your child prefers. Sometimes glaring white paper is too intense
for our eyes.
·
Magnifying reading strips help to focus on the lines that are being read and help alleviate
the stress and overwhelming visual input when reading a long passage in a book.
·
If
fluorescent lighting must be used, permit students to use a hat with a brim to
decrease brightness.
Some of the exercised prescribed by a
developmental optometrist combine motor skills with vision concepts. For example, look at an arrow drawn on a
chalk/whiteboard in front of the student and ask him to point his arm in the
direction of the arrow; bouncing a ball as many times as possible with the
right hand while calling out ‘right’ and then switch to the left hand and
calling out ‘left.’ When children have
mastered this, switch between the two hands.
There are many other fun exercises and games which work to strengthen
visual-motor coordination. One of my
favorite websites is www.eyecanlearn.com
it’s packed with information and exercises you can do at home.
·
Hit
balloons with a partner
·
For
figure-ground (finding an item when it is presented in a busy/complex
background), find and pair socks; use a dictionary to look up a specific word;
complete word search puzzles
·
For
visual memory (remembering information that is presented in the short-term
which is important for reading comprehension and math problems), look at a
picture for thirty seconds and then ask questions about the picture; highlight
key vocabulary words in reading passages and ask children to look for them;
provide a sheet or paper on the child’s desk vs. asking him to copy from the
board.
There are
other visual concerns that are common in both children and adults. Any time headaches, light sensitivity
(including when driving at night), reading and writing difficulty, dyslexia, difficulty
noting left from right, watery and tired eyes, and/or reading comprehension
difficulties are suspected, it’s best to have a full examination by a
developmental optometrist.
