Signs That Autism Is Impacting Vision

Dr. Russel Lazarus, January 30, 2022

Autism is a growing concern around the world, with autism rates more than doubling in the United States since 2004.

Autism can impact a child’s vision

Autism Spectrum Disorder (ASD) is a group of developmental conditions that can cause social, behavioral and emotional issues.

According to the Centers for Disease Control and Prevention (CDC), autism tends to be more prevalent in boys than in girls, and affects roughly 1 out of every 44 children.

Common symptoms of autism include:

Language delays
Trouble adapting to a new routine
Difficulty making eye contact
Repetitive actions
Avoiding touch or physical affection
Problems relating to other people

Along with some of the more well-known signs of autism, people with ASD may also have problems with their vision.

Studies show that children with ASD are 50% more likely to develop vision problems.

Signs of vision problems in children with ASD

Although it is important for everyone to have regular yearly comprehensive eye exams, this is especially true for children with autism.

Signs related to visual dysfunctions are easily mistaken for autism symptoms, so visual problems may go undetected and untreated.

Some behaviors displayed by those with ASD, that may point to vision-related problems, include:

Flapping fingers in front of eyes (known as visual stimming)
Looking beyond/through objects
Poor eye contact
Rolling eyes
Sensitivity to light
Showing either little/no fear of heights or an excessive fear of heights
Turning the head to look at objects from the side of the eyes instead of head-on

If you notice these signs above, schedule an appointment for your child for a functional eye exam with an eye doctor near you.

Eye exams for children with ASD

During a child’s exam, your eye doctor will assess your child for:

1. Eye movement disorders

These are disorders that can negatively affect the accurate and smooth movement of the eyes in unison, making it difficult for the eyes to gather consistent visual information for the brain to interpret.

The most common disorder of this type in people with ASD is strabismus, a condition where the eyes do not point in the same direction.

2. Eye tracking problems

These issues make it difficult for the eyes to track moving objects. Such problems may be the reason a person with autism prefers to view objects with their peripheral vision rather than looking straight at them to view them.

3. Binocular vision problems

Binocular vision refers to the eyes’ ability to work together to collect visual information to be sent to the brain for interpretation.

Children with ASD are often affected by a binocular vision issue known as convergence insufficiency (CI).

CI is an inability of the eyes to converge properly on an object close-up. This can cause problems when attempting to read or write, including headaches, blurry vision and difficulty focusing for long periods of time.

If your eye doctor finds these or other vision problems, they may recommend vision therapy.

How vision therapy helps

Vision therapy is an evidence-based, doctor-prescribed regimen of in-office and at-home eye exercises aimed at improving the connection and coordination between the eyes and brain.

Your eye doctor may choose to supplement these eye exercises with vision therapy aids such as Wolff Wands, prism glasses and balance boards.

A customized vision therapy regimen for a person with autism will work on improving visual processing to help them understand and interact with their surroundings more comfortably. This will help lower anxiety and allow them to more successfully socialize and verbalize their needs to others.

Some specific visual skills that these vision therapy regimens may emphasize for improvement may include:
