I gave a workshop on vision loss and wanted people to understand a little of what it’s like to have partial sight.
Everyone blind or partially sighted is completely different from everyone else blind or partially sighted. In fact everyone, sighted or not, has different vision from every other person in the world, but it took loss of vision for me to realize this.
But although no two of us are identical, there are some patterns to sight loss. And so I sketched five basic geometries. I think my audience found this helpful, and I learned a lot from thinking about them and trying to draw the pictures.
Where I’ve shown black please don’t think a person will necessarily see black. They might in some cases, but very often the black just means there is no visual information. I have a very large blind spot. But I’m not aware of it until I can’t see something. You can’t put that in a picture. Black would be wrong and so would white. You can’t draw nothingness.
Here are my drawings.
