WOW!! Hans.. are you a mind reader? I've been meaning to post on the list about having similar eye/vision problems as you mentioned you're having. I've tried two different brands of eye drops with one - "Clear Eyes" - stinging badly each time I used the product. Needless to say that was good incentive to trash THAT brand! The other is.... is..... (thinking).... is.....oh RATS! I can't recall the product's name and the bottle's upstairs in my nightstand while I'm downstairs in my wee little office. Either way, it gave me very little relief. First thing tomorrow I'll be off to the drug store to see about the product you've recommended..... THANKS!! By the way.. chances are the reason you're not so tired now is that prior to using the eye drops you MAY have been seeing out of one eye at a time - switching back and forth between both eyes at an unbelievably rapid rate. VERY fatiguing according to the optometrist I went to 2 years ago with the symptoms you mentioned. He added a "prism" to my glasses lenses and mentioned the fatigue might be helped by that addition (it wasn't and nor was my vision noticeably improved by the prism). Thanks again...

It can e.g. cause double vision. The eye-problem I want to talk about is the effect of dry eyes on PWP and a possible solution. Dry eyes can be a symptom of PD. And I have them. The effects are vague vision, sometimes double vision, burning irritated eyes, trouble reading, tired fast reading, computering, etc, etc. Since I haven't read about on the list yet, I thought I should mention the great releave I got using eye-drops (Methylcellulose 0.5 percent solution). The expected result was that I got a much clearer view, could read and compute for longer times, etc. The surprising extra result was that I became much less tired not only with reading etc., but also in general!!!!! In the Netherlands methylcellulose-solution is available in two versions with different additives. The first one I used irritated my eyes instead of helping. The second one workes great. So if one doesn't work, try the other. Since eye-problems of course can have several causes besides the ones mentioned by me, I advise you to consult your doctor first!! I hope this will be of some use to someone! Hans van der Genugten <[log in to unmask]>
