Bifocal Glasses Done Right!
I was on a mission to find a pair of bifocal glasses that I could actually use. You know, the kind where it's a spit lens straight across (Franklin style). I not only found what I was looking for, but was also able to specify the height of the dividing line separating the bottom portion of the lens from the top. The glasses were made perfectly according to the measurement I gave. Way to go!
