There
are many skills involved in
using the eyes for vision.
1. A child must be
able to fixate on a visual
target such as the rattle as
she
reaches out to grab it.
2. A child must
be able to keep
the eyes on a moving target to
visually
track it as she tries to
shoot the moving duck in the
carnival.
3. A
child must use small saccadic eye
movements
to move
from one word to another in order to read.
4. A child must be able to use
both eye
together in order to see three dimensional
objects
with binocular
vision.
5. A
child must be able to localize
a
moving target amongst many such as
when swatting at a bubble or
finding mommy as she
walks in a crowd.
6. A
child must be able to converge the eyes on
a target such as a ball as
it
comes closer and closer towards the
nose.
7. A
child must have good visual
perceptual skills
to understand
what she
is seeing in order to read, write, draw, do
puzzles and connect dots.
8. A
child must be able to visually
discriminate
differences in size,
shape, directionality and color, especially
in a
busy background.
9.
A child must have good visual
memory to put
all of these skills to use
after learning something new.
10. A child must demonstrates good eye-hand
coordination
to perform
tasks such as threading a needle that requires much
control.

A child of course
must also have good eyesight which is evaluated by reading the
letters
on the Snellen chart in the doctor's office in order to put these
skills to use
in
functional vision activities. Some optometrists only address the
eyesight issue,
others look at functional vision and how it impacts
school work and daily living skills.
There are many
other
visual problems and diseases such as
cataracts, glaucoma
and macular degeneration which mainly affect
older persons and will not be addressed
here at this time. These
ailments require a visit to an ophthalmologist, a medical
doctor who
specializes in eye diseases. Please
visit Low Vision for
more information.
Some Common Visual Problems
seen in Children
A
child will
probably have
difficulty with binocular vision
when one or both of the eyes
turns inword or outword. The
eye muscles may not be working properly and one eye
may be
stronger than the other other causing the stronger eye to do all the
work. This
is often seen in individuals with muscular disorders such as
cerebral palsy and genetic
abnormalities such as Down's syndrome.
This condition may be quite obvious and
parents usually will bring
their child to receive vision care at a young age. Many children
are helped by vision therapy which may involve special
lenses, prisms, computer
programs and other techniques. Some
doctors
recommend eye exercises or patching.
However,
sometimes visual
problems are less obvious unless the child is
bumping into things
or overreaching. Children may avoid fine motor activities
which they
have difficulty with due to visual problems and their problems
may not
be identified until they are required to read and do paper and pencil
work. Sometimes when the eyes don't work well together a child slants
her
head to the side so
that only one eye is viewing the paper. Another
clue that something is
wrong is when
a child skips words or lines while
reading either silently or out loud. Visual
problems
should be
ruled out when children are having difficulties learning how to
read.
This requires
more than just reading an eye chart.
Children are
typically
able to visually track a slowly moving object
with isolated eye
movements
by the age of
three
years. This means that the child only moves her eyes and not her head.
This requires
good abilities to stabilize the head and fixate. Some
children with sensory integration
or visual
perceptual problems find
this very difficult to
do and they move their whole bodies rather
than just the
head or eyes
when shifting the gaze. These children may also shift their bodies or
rotate paper
when changing directions on a maze rather than just
controlling the pencil to change
directions.
This is another red flag
to look at visual and perceptual problems which impact learning.
Another
visual problem often
identified is school is difficulty
shifting the vision from the white
board to
paper and back again or
shifting vision from one part of the paper to another part of the
paper. Such a
child may easily lose her place while reading.
Using a ruler under the reading line
may help to
keep her place.
Activities to Promote good Visual
Skills
Although
it is in the
realm of an eye specialist to treat visual
disorders, caretakers, teachers
and therapists can encourage activities
which promote good visual skills.

Stereograms
Stereograms
are 3D images hidden within
another picture. Relax, stare at the picture, and the
image will
start to take shape. It may help to begin staring with your nose close
against the picture
and then slowly move away from it until comfortable.
