I will be 64 in a couple of week's time. I found the fonts to be a little on the small size when I changed from Windows three years ago but I got used to them after about a Month. I wear Varifocals, have done for fifteen years now.

The short of all this is I found myself getting used to the font sizes after about six weeks and they didn't bother me after that.

Chin-up, you will find after a while it won't bother you either.
