Now, of course, I've talked to a pilot friend who tells me that progressives totally suck, I agree with his verdict, but for a different reason (I wasn't flying when I had 'progressives'). I found that the cone of correction is -narrow-; I found it necessary to move my whole head side-to-side in order look left and right across a page (or my computer screen, etc.); I couldn't just move my eyes because left or right of center, acuity suffered. The vertical angle also is, or seemed to be, small. So, what's the verdict from my fellow "old farts" on this group? Do you guys wear "progressives"? Or do you prefer the "lined" bifocals? LensCrafters has a 30 day money-back guarantee (I don't actually have them, yet), so I can change my mind. I chose bifocals (a few years ago), and as my eyes 'hardened up' I went even to trifocals. I did have to play with the location of the 'lines' since that equates to the vertical angle where the correction changes. I'm very pleased with 'lined' bifocals and now trifocals (I've required glasses since I was 14, almost 50 years now, so I was already accustomed to the limitations spectacles impose). george |

Tri-s are the answer. My mother was an avid bridge player. She pointed out the value of the intermediate zone in trifocals for looking at the bridge table. The instant I put them on, I said, "This is right!" Looking at the instrument panel is the same distance as the bridge table. Any prescription for bifocal lenses can be used for trifocals. They put the middle zone half way between the distance and reading prescriptions. You can play with the vertical placement of the lens structure. It's easy to go back to bifocals if you don't like trifocals. |

I did have to play with the location of the 'lines' since that equates to the vertical angle where the correction changes. I tried the tri-focals, but hated them with a passion. I do too many things and the lines were never in the right place. After a couple weeks I told them I wanted to go back to bi-focals. It only took a couple days to get used to the bi-focals. I was never able to make the blended bifocals work for me, but it was the tri-focals that were by far the most aggravating. I'm very pleased with 'lined' bifocals and now trifocals (I've required glasses since I was 14, almost 50 years now, so I was already accustomed to the limitations spectacles impose). You youngsters just adapt faster than those of us who have been around for a while. :-)) Roger Halstead (K8RI & ARRL life member) (N833R, S# CD-2 Worlds oldest Debonair) www.rogerhalstead.com george |
