I am also not sure what magnification level I should look at 3X, 10X.. just not sure. As we get older this is more of a problem and frustration. I wear bifocals but I find them generally useless for almost any task.. and probably take my glasses on and off 50 times a day. I'd rather not have to set up to take a photograph - just be able to pick up a coin and examine. Any suggestions would be appreciated.
