The interesting thing here is that my vision is really poor in low light and generally like Baby Boomers and all people over 40, I cannot see close up very well.  

However, what you see demonstrated here is my long distance vision is still pretty good. Shoot on a walk last week, I saw a squirrel race up a tree 20 feet away. Too bad this kind of vision is terrible for seeing treats in front of my nose.  But seriously who wants a treat that far away? Not me.
