I woke one morning with a black hole in the vision in my left eye Jim, I was hospitalised immediately with the assumption that I was suffering from age related macular degeneration. The light sensitive rods and cones fall away, also high blood pressure can effectively blast them away.
After 22 months the doctors gave up on a diagnosis, but to prevent further damage the elements around the hole were welded back into place with a laser.
The end result, for me, was a hole in the centre surrounded by a larger area of distorted vision so that I see nothing straght ahead but retain peripheral vision, which frankly is worse than no sight at all!
Sitting at this computer I see two of everything, if I close the affected eye and stare at a word on screen then switch eyes the left one is looking down and to the right.
I was 60 at the time and was told that I would adjust to the loss of depth perception, had I been younger that may well have been so, but not for me.
Reading can only be accomplished by closing the left eye, trying to locate the head of a screw etc is a trial and error job.
If you have ever read my posts on the jigs thread you will see that I use jigs extensively, they keep my fingers away from the sharp rotatating parts!
In addition the left eye sees things as being smaller, my brain interprets that as being further away, again not helping when judging how close a cutter is.
Beyond about 20 ft I have no problem and can easily pass the DVLA eye test.
What really upset me was I was taking flying lessons but I can no longer see the instruments clearly, so that went overboard!
I was concerned about driving but the DVLA stated at that time that I met their requirements.
Like you I bump into things on my left side and trip over things 'cos the damn floor isn't where my eyes tell me it is, stairs are a nightmare, especially descending, but fortunately I live in bungalow.
You adjust as best you can, as you will have.
