I find I have so much trouble with dryness. I use moisturizing eyedropper to deal with the issue. I also notice that my vision gets worse the more fatigued I get.

Not sure what a stick on prism is, have some idea. My husband got prism glasses , prism build in the glasses, that might work better.I hope you find something to mange your double vision.

My husband has a lot of vision problems and double vision, he gave up driving 6 years ago. The doctor prescribed prism glasses, the prism glasses help a lot with the double vision.

I also have blurred vision after reading awhile. I end up stopping. It goes away . I do need to get my eyes checked.😊

I’ve had issues with dry eyes years before my diagnosis with PD. I use moisturizing eye drops and the help. But lately I’m having random blurred vision. I have to look away and look back or close my eyes to clear it. Could be from the increased dryness.
