Progressive Lens glasses vs tri-focals

Progressives are easier to adjust. The Line you have to deal with is not there. Just make sure you tell them where you usually work/focus. I use my glasses a lot for computer, so I had them move the middle focus up. Leaves plenty of room for book reading on the bottom and walking/driving on the top. They can make the settings according to your needs. Easey peasey.
Yes, indeed. I have been wearing them for years and would not have any other kind.

I have used lineless bifocals for years. The first week of using them was not pleasant but my job required reading reports on regular basis as well as talking to others. I hated the thought of using reading glasses stuck down on my nose. After the short period of getting used to them I wear glasses during all my waking hours and would be lost without them. They have never bothered my photography in the least bit.

I love mine. Never had a problem. Since you are used to trifocals, you shouldn't have any problem. My lens are about 1 by 1 1/2 inches.

I've worn trifocals for years and am considering the new generation of progressive eyeglass lenses. Anyone have experience with these new eyeglass lenses and if so, how do they affect viewing through the lens? Should add that I have adapted to the difficulties associated with trifocals, but would like an improvement if anyone can attest.... 8-)
I have worn trifocals for about 40 years. About 20 years ago i tried the progressive lenses and found that looking straight ahead they were wonderful, but my peripheral vision was blurry, making driving difficult. I traded them in for new trifocals within a week. But from others' attestations here, maybe they have been improved. I like the idea of getting them somewhere where you can return them. I recently had cataract surgery and had a bad reaction to the post-surgery drops, and am currently nearly blind in the eye that was supposed to be fixed. I am assured that in a few months all will be well, but it has given me a greater appreciation for binocular vision, and vision in general.

I've been wearing progressive lenses for years without issue, other than if they don't get my prescription right. Just one thing, the lenses can be made out of a couple different kinds of plastic. One is the standard plastic, the other is polycarbonate, which is lighter. Unfortunately, some, me included, can't take the polycarbonate lenses, as they seem to make everything fuzzy. So plastic works for me. I think mine are what's called Crizal. don't know exactly what that is, but it like it, and things aren't fuzzy. An optometrist once told me the problem with the poly is something to do with presuming of the light rays, or something. YMMV, of course. But I'd say, if the trifocals aren't working out for you, for for the progressives.

Sorry for previous post. I have worn progressive lens glasses for 20 years or there abouts. I have never had any problem with them and never noticed them when using any of my cameras. The one change I made was in getting dark glasses without polarized lenses, but that had nothing to do with the progressive lenses and more about not being able to see the lcd screen on my D600.

I've been told that I will probably still have to wear glasses after surgery but nothing like I wear now. I won't even walk in the dark without my glasses now. Again, the evaluation next month will tell the tell for me.
David; what type of surgery? IOL replacement? If so, you'll be amazed when it's completed. Went through it about 3 yrs ago, almost painless, less that a week to full recovery for each eye. Normally they do each eye about 2 weeks apart. You'll probably have to use glasses only for reading and computer work, but I use "off the shelf" ones from one of the pharmacies.

I wear bifocals. Hate having glasses on when I'm shooting. I bought the +1 diopter eyepiece for my Canon MKIII. That gave me enough correction additional adjustment so I can shoot without my glasses. Of course I can't see squat on the playback screen so I rely on the histogram.

Oh ... getting older ain't for wimps ... LOL I have that same issue .. don't know how many reading glasses I've lost out in the woods now ... they are camouflaged in the leaves and sticks when I suddenly take them off to look through my viewfinder, and then I can't find them because I can't see! :roll:

Being in the business,I tried a lined bifocal when I started becoming presbyopic in my 40s-thinking it might help me in surgery. They drove me crazy. I suppose I could have adjusted,after all,I had worn glasses for years for myopia(near sighted). I adjusted the the progressive quickly and began recommending them to my patients. The downside was distortion,particularly when looking to the side. With modern lenses this has been greatly improved and I think progressive lenses are the current standard. Keep in mind though,quality varies and,although they can be expensive,I would recommend getting the best exam and quality lenses available. A switch from a trifocal should be an improvement. By the way,Crizal is an antireflective coating that is baked on at the factory. It is more durable than the locally applied coatings and actually hardens the plastic lenses. It's a little pricey but I recommend it.

Thanx for clearing that up. I thought it was a special type of plastic lens.

It depends on your ability to adapt. I went from single vision to bifocal with no problem. I couldn't deal with trifocal - drove me nuts! Moved on to progressive and have never been sorry. Had no trouble adapting and have been several cycles of improvement in the progressives. Never sorry.

I have worn the progressive lens since they first came out. 1st pair took me about a week to train eyes/brain how to look through them without consciences thought. Since then no problems, I really did not like my old bi/tri focal lenses. I would need an awful lot to make me give up my progressives

One factor to consider is whether you correction includes astigmatism. If so, sitting crookedly, even minimal, is not good. Having bifocal/trifocal lines makes the straightening job easier. Since getting implants (bad cataracts), my astigmatism has receded to virtually none and bottle bottom lenses have gone very thin, so I am thinking my next lenses could be progressive.

I have bifocals and have tried twice to go to progressives and did not like them. For some they work for others like myself they didn't. I recommend if you try them to use a eyeglass shop that offers a return policy which was my case. Took the progressives back and went to line bifocal which wound up being cheaper. Best of luck to you on this matter. 8-)
