When I first lost my sight I could see streaks of bright gold light when I was in direct sunlight. Over the years I’ve lost that ability.
Last week I wrote about the fact that blind people are not all the same – that we have individual strengths and preferences in how we accomplish tasks. The same can be said of our blindness – blindness is a spectrum that covers a range of degrees of visual impairment and partial sight.
Basically, I’m saying that we all see different things.
Even those of us who are totally blind may have different experiences of how that appears to us. For me, as an example, I “see” a blank background colour that differs (I think) as a result of the level of light in my immediate surroundings. It can be any base colour from a rose pink to a dark gray. But that’s not all I “see”
My vision is filled with a constant flickering of pure white, gold, green, red, and blue pinpricks of colour that flash on an off as I watch them. I often refer to them as being like visible pins and needles. They are very pretty and are constant – whether my eyes are open or closed.
But most of my friends who are totally blind “see” something different.
Looking beyond those of us who are totally blind, I have friends who have various degrees of residual vision. Some can still see a computer screen, though they need to use a screen magnifier to be able to read what is showing. Some can see blurred outlines of objects around them, but only if there is a significant contrast between the colour of the object and the environment around it. Some have a little usable vision during the day but are night-blind. And some people have eye conditions that mean their levels of vision varies from day to day.
There are almost countless variations on what we can each see as a member of the blindness and visually impaired community. Which is another reason why the tools and techniques we use may differ from one person to another – why some of us use mobility aids like white canes and guide dogs to navigate, where others may seem to be able to navigate around without difficulty in some circumstances and struggle in others. Why some of us have smart phones and computers that talk to us, and why some of us use screen magnifiers. And why on some days a particular person may see something that they may not see on another day.
In truth, visual impairment is a continuum that ranges through a wide variety of visual experiences. And that impacts on the way each individual member of the blind and visually impaired community engages with the world.
