Ever the white rat here, I ordered up a pair of blue tinted glasses to see if they would help my growing issue with dyskinesia. First of all, they were cheap and arrived in record time. Secondly, you won't win any fashion awards wearing them... very Lucy In The Sky look.
I've only worn them a day and I'm not sure that they are helping the Dysk but, I have been having nasty vision issues that I attribute to my PD. I get blurring around the outer edges of my vision and severe flaring from headlights or the sun. I can tell you that these glasses fixed the flares immediately and generally seemed to sooth my eyes particularly when driving. For that if for nothing else, I would consider the $14.99 I paid for them to be money very well spent. I will report back if I experience any other plusses.
