Thanks, I have exactly the same symptoms; convergence and spatial awareness.

I went to a specialist in Cardiff whom recommended my first ever pair of glasses. It was quite a revelation when I was told that I trail my arm on walls and railings because my sense of distance was so poor - I didn't realise I was doing it for that. She tried me with prisms but that distorted the whole world like being a hall of mirrors and couldn't deal with the false horizon it game me.

My glasses help deal with the convergence problems and have made a huge difference to me. I don't feel so unsteady.

I also have a referral to ENT (Ear, nose and Throat) clinic to check for labyrinthitis which may be contributing to some of the balance problems.

Interesting about the macushield - I had never heard of it before. Do you think it works ?
