you need to get this checked out. pd does cause problems with color contrast perception. when i first experienced sinemet i suddenly had a fresh view of the textures and color in the carpeting as an artist thus has been upsetting i love the use of color sometimes -- when first waking up, i open my eyes and see a strobe effect my sight dims and brightens very quickly -- oscillating and then it is gone i've asked every doctor i've ever seen and they don't know what i'm talking about i hope you are o.k. let us know if you find anything out.
