Diplopia (double vision) has plagued me for years, as you know Norbert,
it can make you feel very disorientated and you lose the natural ability
for spatial awareness.
It certainly can effect confidence, what you see and what you can detect
from touch, can be two different things.
I tend to over grip things like glass and china, because I can be clumsy,
but when I leave go of whatever it is, I can cause most damage with my
hand wandering free, If that makes sense 
Quite often I don’t use my knife and fork, it’s easier with fingers, although
I can drop just as much 
Pull on shoes, and Velcro fastenings are a blessing in disguise 
As you may already know Norbert, your optician could suggest prisms
to cope with double vision. This is a double edged sword. As long as
you sit still and look straight ahead it’s the answer to your prayers.
Once you glance side to side, or walk around, it can feel as though your
eyes bounce against the prisms (like nystagmus), it compromises ability
to control balance and effects spatial awareness.
However, my eye got so bad, it was turning into a squint. At that point I
was able to have surgery to realign the eye muscle, I could tell there was
an immediate improvement in the severity of double vision, apparently it
can take up to 3mths for the eye to settle.
Ask your Neurologist to refer you to an Eye Specialist.
