Anyone here on Cogentin that can help me answer my question?

I have been taking Benztropine for Parkinson's for about 4 years now and have just now heard of these side effects about blurry vision.

This time last year I decided to quit smoking and went back to church after a decade, and I'm watching the preacher and I blinked, and when I closed my eyes I saw this.

A strange circular pattern of rings around my eyes, this is where they start, but it gets weirder. Only in certain places do they occur and usually they tend to be around people or animals.

Is this common for this pill or am I gaining a gift of some kind?
