I recently learned the name for my visual deficit – left homonymous hemianopsia. I have always had difficulty describing what I’m experiencing. Now I can share some visual examples. Remember that none of the black or grey areas are visible…it’s just the smaller field of visibility that I see. The first photo is a good representation of the field cut. The second series shows the out of focus left half that the brain is trying to fill in. That’s what happens to the left side of people’s faces for me!
Finally the link is a video of someone walking around with this condition, though on the right instead of the left. You can see how disconcerting it can be to be aware of missing so much.
I do have some upper left vision but none of my lower left vision currently. So my field is somewhat better than in these examples.
