All this talk about flicker, I can't hold my tongue for long:
A mysterious part, of my cluster of neurological symptoms (LYME diagnosis), is a visual 'flicker', that, I discovered, is in sync with my heartbeat. Opthomologist checked for detached retina, (nope), and happens in either right or left eye.
I've always assumed it was a high blood pressure thing, as perhaps pressure surges cause the light to dark oscillations. Happens with reflected sunlight also,off nearby lighter colored surfaces. Annoying at first: I went to check the lamp cord !
Rate, like I said, in sync with cardiac pressure impulses, rate at 1/50 hz (that's with Bradycardia,
50 BPM).
West coast doctors not keen on discussing LYME disease, as a whole, for whatever reason.
So, anyway, I know about distracting 'flicker', for
sure, lol.
