My optometrist made me a set of glasses that achieve optimum focus at 18 inches, specifically for working on my desktop computer. They’re also okay for use with the phone, since focus is decent up to about 12 inches, and they’re fine for chimping. I have a separate set that were meant for driving and achieve optimum focus at about 15 to 20 feet, but I use them mainly for watching television. > On Mar 24, 2015, at 11:26 AM, Yolanda Rowe <ypr...@gmail.com> wrote: > > I wore those expensive rascals prior to the surgeries.
