Yes Doug, I too have this vision or trouble of seeing two sun images.  Unusally for me if I see the sun beginning at sunrise there is only one.  But as the sun raises and becomes brighter then it begins to break into two images.   I know that this is due to one eye weaker than the other and having a convergence problem.  My eye doctor has confirmed this.  It is more of a problem when I am tired, which gives me another confirmation that it is a convergence issue.

I will say that it appears that this ‘problem’ is slowly reducing (perhaps the sun is ‘curing’ me???).  I still have the problem although it appears lesser these days. 

Wishing all a very happy and light filled New Year - bobji
