I am still trying to
"I am still trying to get used to these multi-focus readers, which I understand is typical of this type of lens. I find the reading part (the invisible bifocal) to be lower in my vision field than I would expect them to be. HOWEVER, I am doing some "diamond painting" crafts with tiny pieces placed on a hard-to-read gluey canvas. . . but I just put these McKay glasses over my regular reading glasses, and I can read the tiny letters quite well now. Rah! My overall impression is these will be just fine once I get used to them, but for now, I do love the craft use."
