That's what I have in the bottom half of my bifocals. (I don't want to mess with trifocals, and a few years back they stopped making progressive lenses for the bifocal portion. I can't wear progressives because my RX is too radical.) Why? By doing the measurement and then sitting in his machine with the numbers dialed in, the lenses came out exactly right the on the first try. -- Jim Pennino Remove .spam.sux to reply. |

If the change from distance to close work is sufficiently radical, you can't get from there to here in just two inches.

No; why "try" something instead of taking measurments? -- Jim Pennino Remove .spam.sux to reply. |
