      Promoting Visual Skills            

        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.

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.


Babies

  • Present simple shape books to look at
  • Place a moving mobile to look at from the crib
  • Place baby on her belly so that she looks upward to reach for toys
  • Carry baby around in a backpack or front carrier facing outward so                                                                                      that he can look around while you take a walk
  • Prove push button toys which make things pop up or move


Toddlers and Two Year Olds
                                                                      
  • Encourage pointing to named objects in the room and pointing to                                                                                       pictures in a book
  • Tossing objects into containers or to another person
  • Form boards, shape sorters, nesting cups, ring stacks and other toys                                                                                     to develop eye hand coordination
  • Swatting at bubbles or suspended toys like a light  tetherball
  • Scribbling with crayons
  • Imitating finger play songs
  • Rolling a ball  back and forth
  • Lots of movement activities 

   Preschoolers

  • Filling a bottle with mineral oil and water, add food                                                                                                                coloring and  enjoy the sight
  • Tossing and catching a large ball

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.
