Zenni, my first bifocal
The order from 2/1/12 arrived, today, 2/21/12. They got the correct number,
and style of frames. A couple of them seem a bit stronger, a couple a bit weaker. I don't have a gadget to measure the correction. Who can tell? I did a primitive test of trying to read some text typed on a sheet, on the far wall. Maybe 16 point text, at 8 feet. The bifocals are a bit odd. The reading part is OK out to about 8 or 10 inches. Didn't actually measure. the distance lenses seem OK from maybe 10 inches, on out. The reason I've always had to get new glasses, is hard time reading the street name signs on the poles "MAIN STREET" and the other street. Will have to go take a drive, and see if these are any better. For the price, I can't compain too much. Would be nice if the reading focuss part was in focuss to my fingers on the computer, at least.
