You surely have persistence. I think if you have eye problems, that’s
a definite symptom you can document. I’ve heard of many people unable
to work because of vaious symptoms. A hairdresser who couldn’t hold
her arms up because of muscle weakness, a programmer who couldn’t concentrate
and a pianist whose hands had tremors. No matter what you do, it can
be affected.
Do you think you’ll be able to work again in the future???
