Have had vision issues predating dx, too many new lens prescriptions, spare pairs of specs everywhere - intermittent blurriness, and sometimes a fading of vision. Opthalmologist said this is lack of dopamine in the eyes - sinemet improves it, new lenses don't! Well, for me at least. Everyone is different, so this may not be your problem, but it seems to me that I have met an awful lot of people online who have experienced blurry and/or troublesome vision. Also exacerbated by very slow re-focusing, and slow eye movements in general when undermedicated.
