When I first started to wonder about my own sensory issues, I kind of dismissed the visual channel because I wasn’t aware of the same degree of sensitivity as touch and sound. I wondered if there was much for me write under this heading. Then I began to remember things.
All the walls in my home are painted; plain colours, no wallpaper. Same with curtains and blinds. I have a problem with repeating patterns on wallpaper or fabrics. My brain has to follow the pattern repeatedly, tracing the shapes over and over with my eyes, looking for meaning in the shapes, relationships, connections. It becomes exhausting, irritating, and again leads to that inner nausea of overwhelm.
I remember buying some lovely-looking jungle-leaf pattern wallpaper that, on the roll, seemed to have a gloriously random pattern. Can you imagine my horror as with each new strip of paper on the wall, more and more of a huge diamond-shaped monstrosity revealed itself. It was unbearable. Whoever heard of a diamond shape regulated jungle? But I had to live with it because we had no money to buy new wallpaper. I spent the next several years trying not to look at the wallpaper in my living room.
I also cannot but help reading text of any kind. It is what my eyes are drawn to. Text on packaging, car registration plates, signs, labels, subtitles when I don’t need them. Car regs and labels are worst as my mind tries to make words out of random collections of letters. I find myself having to drag my gaze away time and again, with overload leading to that sick, exhausted feeling again.
There are colours that I can’t bear. Mustard. I hate mustard-yellow. I hate many shades of yellow and orange. I hate most shades of brown. Beige – bleuch! I dislike most colours that are at the yellow end of their spectrum; blue-toned red, fantastic, yellow-toned red, get it away from me.
I do love colour, though. Bright, electric colours. Bright walls. Flashy flowers in the garden. All the shades of green in a woodland. Jazzy colours for my clothes, or all black. Extremes, not dull in-betweens.
My sensitivites are mild, leading to general irritation rather than being unable to function but that’s not the case for many autistic people. For some, any of the above and levels of lighting or types of lighting can be excruciating, as an example. It means they cannot go to shops, or struggle in official buildings such as schools and hospitals. There are probably many more aspects of visual sensitivity that I don’t know of.
Having said that, if my other sensory channels are on overload then patterns, text, and colour-overload can be the final straw that leads to a shutdown and abandoning whatever I was trying to do.
If you suspect you are autistic and notice you find some environments exhausting or repeatedly get irritated in certain settings, take a look around you. Is there a common visual theme? Are there ways you can reduce the impact? Sunglasses can help some people in some situations. In your own home you may have more control.
If you know someone who is autistic, watch their reactions to visual input, especially if they are non-verbal. Pay attention. What can you do to help lighten their sensory burden?
