Visual Perception & Autism
Some people on the autism spectrum have problems with filtering visual information which in turn distorts perception and what one is seeing, interpretation what someone takes out of what is being seen in terms of context and association and mentalisation that ability to internalise and integrate the visual memory in the form of a coherent, connected and retrievable memory.
What Tints Can Be Used For?
If people live in a world of being object blind and meaning blind and ultimately context blind this can have an impact on socialising, bounding, learning and having the ability to retrieve multiple forms of incoming visual information at once. Tints work for people in different ways (if they are needed at all) – for some its sensory integration disorder, for some it is a level of dyspraxia, information overload and coordination, for some it is building up a visual context because of simultagnosia and/or semantic agnosia, for some its processing faces, for some its recognising and building upon and reading social cues, for some it is getting a sense of “self and other”, for some it is visual learning difficulties such as dyslexia, dyscalculia and being able to read and write with coherence, for some its aphasia and/or verbal agnosia and gaining a better grasp of language.
70% of incoming information is visual and we take that information in as light waves – essentially as color. Tinted lenses are filters. They filter out different light waves. This reduces the level of incoming information which leaves a person more processing time. This can have different effects in different people. For some it may just help them relax more or feel more comfortable looking at faces or making eye contact, help them handle places with bright lights or being outside. For some it will allow them to read comfortably and with meaning or improve depth perception. For others it may help them better process language and ultimately speak more fluently. For some it may help them see things as a whole and recognise objects, faces, places, and begin to read context and social cues or have a better processing of a simultaneous sense of self and other.
Tinted lenses have helped me glue together a world which was largely bits and pieces that seemed shattered and unendurable, people shatter into fragments, objects floating with no clear base, foreground and background interchangeable, familiar voices with no face that seemed to match the warmth of familiarity. My language was also impacted to a certain degree with no internalisation of the visuals around me. Now I have tints they have made able to see faces with a level of coherence, looking at faces now I see a “whole” rather than “pieces” I am able to focus on their movements, body language and words, I can walk down the street and look at faces, places and people with a level with a level of coherence, I am able to better gauge “self and other” in conversations. I still have visual perceptual disorders however the tints have opened up and bridged my “non-visual to visual” world greatly.
