I've been lurking on the list for many years. It's been a long time since I've sent a message to the list but when I saw the skeptical comment re blue glass I felt compelled to write. I descovered the effect of blue filters on dyskinesia about 12 years ago. The impact is dramatic. For optimal results the lens should be what I would describe as a deep sky blue and held up to the periphery of the eye (at the temple). I stopped exploring this phenomenon when I realized that the impact was transient and was not effective in all people with dyskinesia. But when it works (as in the video) it is very impressive. ************************************** See what's free at http://www.aol.com. ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
