>Bill you are right about how vision affects the accuracy of our work. I have some tired old eyes and some glasses with bifocals. I use my prescription glasses for most of my work. However I often use a pair of +2 cheap non-prescription �cheaters�. The lighting is critical and which side of the saw I look at in aligning the saw to the cut line makes a difference. As they say�the devil is in the details�but sometimes the details get fuzzy.

>I do best with a set of lenses that I had made for computer work six or eight years ago. They're comfortable, and paid for.

Bifocals and close work don't work for me. Can't really explain why.

But a good note to remember for all of us. Thanks!

>I build houses for a living and when it gets down to trim work and punch list items...it seems like my bifocals are just the wrong distance for the work. I usually end up doing what I did before bifocals....pull my glasses down my nose and look over the tops. ;)

>I have exactly the same problem with my bifocals - look over the top or take them off. About ten years ago I was helping a friend trim out some doors and I had to tip my head so far back to be able to see the miter that it hurt my neck.

What I did was get a different prescription for glasses that gave me a zone of sharp focus between 1.5 and 4 feet. Single lenses, no bifocals. Sure helped a lot.

Can`t remember who makes `em but...

>I`ve seen flexible lenses(think contact lens) that can be stuck to the inside of your glasses to allow you to do things like peel them from the bottom of the lens and move them to the top for overhead work or even place them on another pair of specs or a SCUBA mask.

Your local eye Dr. should be able to hook you up.Be sure to tell him your expected focal length(distance from your eye to the work).

>I used to work construction and ran across a sheet rocker that had gotten some tri focals made with close vision lenses on BOTH the top and bottom. I don't remember the focal length, but he said his optometrist was very helpful. He also said they weren't that much more expensive than "normal" and that the optometrist said it wasn't that unusual a request.

I'm currently using progressive lenses, and I love them. I just move my head slightly up or down to change the focal length. I've been doing it long enough that it is automatic, now.

Progressive lenses here, too

>I love them; although my vision has changed enough that I need a new prescription, sometimes have to take them off for close vision. Yeah, I'd buy some new ones except they were soooooo expensive when I got them 10 years ago. Hmmm, maybe they're a bit cheaper now.

>I have a pair of those, they're called occupational bifocals (or trifocals). I was doing a lot of close work overhead & couldn't bend my head back far enough to see what I was doing. I like them most of the time. The downside: You have to get aviator or other large style lenses to fit it all in (OK for me - I got OSHA approved frames & lenses and side shields) and trying to focus on a large vertical area - like supermarket shelves - can leave you bobbing like a pigeon looking for the right lens.
