Overcoming sudden vision impairment ...

[Gordy]

Thank you all for the advice.  I'll especially listen to the medical professionals in the bunch.  

As Mr. Thomas related, my issue is indeed neurological, and there's nothing wrong with my eyes. I have had some slight improvement in just these past few days with focus in general, so I think what's left of my brain is trying to overcome and compensate.
Shooting has also improved having dropped bow weight and distance expectations for now.

thanks again ! trad gang is the best !
