Same Heron, Different Day

I'm having a little trouble with my vision so I have to totally rely on the camera to focus.   My doctor has me putting warm, moist cloths on my eyes twice a day followed by drops to address my extreme dry-eye.  For some reason, today I had a real nasty cloud over my left eye and everything was blurred.  It cleared up this morning but I'm still not seeing clearly.  Heaven knows what my blips will look like for the next couple weeks. I'm going to have to put all my faith in Nikon.
