Unusual visual examination of objects in infants may indicate later autism diagnosis. Unusual visual inspection is defined as: looking out of the corners of the eyes, holding an object up very close to the face, looking at something with one eye closed, or.
A common binocular vision issue associated with ASD is convergence insufficiency (CI). This condition causes an inability of the eyes to converge together on an object close-up, making tasks such as reading or writing especially difficult.
Studies of eye clinic records also suggest that autistic children are prone to serious vision problems: Among 2,555 children at a university autism clinic, about 11 percent had significant vision disorders, including strabismus, in which the eyes are misaligned, and amblyopia, in which poor vision in one or both eyes ...
A broader top face, a shorter middle face, wider eyes, a wider mouth, and a philtrum are some of the common facial features seen in children with ASD [16,17].
Children with autism have a broader or wider mouth and philtrum - the groove below the nose, above the top lip.
posturing – holding hands or fingers out at an angle or arching the back while sitting. visual stimulation – looking at something sideways, watching an object spin or fluttering fingers near the eyes. repetitive behaviour like opening and closing doors or flicking switches.
Visual stimming is one of the self-stimulatory behaviours that children with autism often present with. It may include repetitive behaviours such as: Staring or gazing at objects, such as ceiling fans or lights. Repetitive blinking or turning lights on and off. Moving fingers in front of the eyes.
Children with autism achieve mirror self-recognition appropriate to developmental age, but are nonetheless reported to have problems in other aspects of a sense of self.
The most common eye defects include myopia, hypermetropia, astigmatism, presbyopia, and cataract. These defects can be corrected by utilising lenses to correct the distance between the focal length and the retina or to correct cornea irregularities with laser surgery or lenses.
Children on the autism spectrum typically have a number of similar behaviors that could be associated with a vision issue. Children with ASD may: Widen their eyes, squint or close an eye when asked to look. Stare intently at certain objects or patterns.
In such cases, the person cannot see distinctly and comfortably. There are three common eye defects, and they are(i) myopia or near-sightedness, (ii) Hypermetropia or far-sightedness, and (iii) Presbyopia. These defects are corrected by the use of suitable spherical lenses.
The two most common defects of vision are myopia and hypermetropia. Myopia can be corrected by using a concave lens and hypermetropia can be corrected by using a convex lens.
Fawning is an attempt to avoid conflict by appeasing people. They are both extremely common in neurodiverse people as it is a way for them to hide their neurodiverse behaviours and appear what is deemed to be “normal”.
An autistic person also has difficulty expressing feelings in the same way we do and sharing them. Whether a person is autistic or not, they will have to go through specific steps to express emotions. You can convey emotions from facial expressions, body movements and positions, or even the sound of your voice.
Myth 1 – autistic people cannot make eye contact
This is well known but factually inaccurate. Whilst many autistic people struggle to make eye contact, some are able to, so don't assume someone who identifies as being autistic won't be able to meet your gaze.
Stimming – or self-stimulatory behaviour – is repetitive or unusual body movement or noises. Stimming might include: hand and finger mannerisms – for example, finger-flicking and hand-flapping. unusual body movements – for example, rocking back and forth while sitting or standing.

Stimming behaviour is almost always present in people on the autism spectrum but does not, on its own, necessarily indicate the diagnosis. The biggest difference between autistic and non-autistic stimming is the type of stim and the quantity of stimming.
Masking is a word used to describe something seen in many children with ASD – when they learn, practice, and perform certain behaviours and suppress others in order to be more like the people around them.
Usually, toddlers will flap their hands when they're stimulated by something and are either happy, excited, angry or anxious. In the case of autistic children, it is one of the self-stimulating or stimming behaviors that help them regulate their emotions.
Children with ASD have a diminished perception of their body movement and postural orientation; as a result, they often sit, stand, and walk with postural impairment.
In terms of visual acuity, a person with 6/3 vision has better eyesight than someone with 6/6. People often believe that 6/6 is perfect vision but that is not true. You could have 6/3 vision, meaning you can see clearly at 6 metres what a person with normal vision would need to be at a distance of 3 metres to see.
