 Toddler Vision Development

  • Arnold Gesell – Father of Child Development

“Vision is the key to a child’s whole development . . .” – Arnold Gesell, MD

Vision – Its development in Infant and Child

If a child is failing out of school – “they weren’t developmentally ready in the first place”

Harm – if child is not developmentally ready, it is “Developmentally inappropriate”

Preoperational stage – ages 2-7 – Kids learn through pretend play but still struggle with logic and taking into account another’s perspective (self-centered, me, mine is normal).

AGE 1

Peek-a-boo, pat-a-cake, looks at pictures, normal depth perception, “where is the duck?” – points to objects of interest. Interest in picture books.

  • They won’t know objects they have no experience with.
  • Find out likes/dislikes
  • May hold books upside down and still be interested in looking at the book.
  • Vision should be guiding motor – eyes first, body seconds, look first and then touch!

AGE 2

  • Eye hand coordination, puzzles – blocks
  • Depth perception – playground and curbs
  • Sort color and shape.
  • Fisted grip
  • Scribble
  • Point to objects
  • Stack 4+ blocks
  • Draw straight lines and circles

AGE 3

  • Copy a circle
  • Stack 7+ blocks
  • Smooth eye movements without head movement
  • Accommodates near and far easily
  • Binocular coordination at near and intermediate distances (accurate convergence and divergence)

  1. The child needs to move through space.
  2. They need to touch and move manipulatives.

Toddlers want to help and we should let them:

  1. Learn to do actions independently
  2. Intrinsic reward of being a good helper

    https://www.psychologytoday.com/us/blog/freedom-learn/201809/toddlers-want-help-and-we-should-let-them

    Patient Management:

    1. Parent involvement/behavior difference with and without parent directly involved.
    2. Sit on mom or dad's lap.
    3. Provide choices - red ball or blue ball? Not "do you want to play this game with me" - Do not give them a "no" choice.
    4. Never force performance: explanation of technique so parents can try at home.
    5. Don't schedule during nap time or meal time.
    6. Get on the floor.
    7. Play
    8. Sing
    9. Make the noise - gobble, glug, quack, etc.

    Vision Training Activities

    Ball roll and catch with cup – Be sure to always hold the cup with two hands. Increase the distance between players when ready to increase the challenge.

    Wall Scan with pictures / family photos – Use a large area to place the pictures randomly on the wall. From a distance of 4-6 feet, ask the child to find a specific picture and then go to the wall to take it off. Increase the number of pictures and spread them out over a wider area to increase the challenge.

    Feed the Puppet (spoon) / Baby (bottle) / Monster (straw) – Be sure to present the puppet in all points of gaze (up, down, left, right, center, and all the diagonals). Move the puppet to a new spot each time (saccade). You can also move the puppet in a slow continuous movement and instruct the child to watch the puppet and feed him when he stops (pursuit). Start with larger targets and, when mastered, move to smaller targets. Emphasize the temporal area of gaze (eye pointed out toward ear) to get the eye more comfortable stretching outward.

    Spider Smash – Encourage the child to look and aim before stamping down on each spider. If the child misses, try again until the stamp is centered on the spider. Start with the large size and move to the smaller size when mastered.

    Free Play with patching (equal time for each eye): In order for patching to be effective, it must be done with active eye-hand coordination type tasks. Passive patching, such as while watching TV, provides little benefit. You may incorporate “free play patching” as often as the child will tolerate throughout each day (up to approximately 1 hour). Be sure that there are still more hours of the day spent without the patch to encourage eye teaming. Some good free play activities to do while patching include:

    • block play• puzzles• stacking toys• “driving” cars / trucks• Coloring / scribbling

    1. Use the eye patch for all of the above activities. Spend a little more time using the left eye versus the right eye (approx. 60% left eye / 40% right eye).
    2. Spend a minimum of 15 minutes total vision training time, 4 days per week.
    3. Rotate the activities so that you can spend equal time on each activity over the course of a week. If the child wants to do more than the minimum, there would be no harm in doing so, but would only provide more benefit.
    4. You can also spread out your vision training time over the course of the day, doing some in the morning and some in the afternoon.
