Progressive Lens glasses vs tri-focals

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-)

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.

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-)

I've used progressives for over 10 years now (longer than my serious photography). I do not have any problem at all. You may need to find the "right" position for your particular glasses but, mine are automatically right on. If you have no trouble with your existing tri's then insist they make the progression match them.

M, are you talking about the invisible line glasses?
If so, I've been wearing them for about maybe 6 years. I've actually never owned/used a pair with the actual lines glasses.
I've never had a problem with them of any kind. I will add that I've also never owned a pair with the lens more than 1 inch tall. That means that all three zones are very thin and barely fit on the lens, so I'm always warned that it could be harder to use them, but again, I've never noticed it to be problematic. I wear mine 24/7, yes, while I sleep. You never know when you will need to jump up in the middle of the might a have to snap a pic! NOT! :lol:
I would get then without hesitation. In fact, the taller the lens, maybe the harder to actually use. You would have to move your head more, up and down to be able to use the different layers.
I've noticed that some people have to tilt their heads WAY back to see through the bottoms of the lens. I can pretty much do it by just moving my eyes up and down.
Not sure if this is what you were after. Let me know if you meant something else? good luck. ;-)

I also have tried the older generation of progressive lenses and could not adapt to them due to the loss of 'peripheral' vision. That has apparently changed to the plus side so am thinking about trying them. I use Lenscrafters which does allow returns so agree with you there.

I've worn progressive lens for about six years. I have to raise my head when I use the view finder, but other than that I don't know I have them.

M, are you talking about the invisible line glasse... (show quote)


I've actually done well with the 3 line trifocals but do have issues viewing the finder on my D800 so am trying to make sure if the progressive lens approach is an improvement...

I've used progressives for at least ten years and wouldn't change a thing. They can be difficult to get used to for some people, but once you are used to them, viewing objects near or far becomes very natural and you don't even think about it. There did seem to be some parallax distortion initially at the extreme left/right edges, most noticeable at times when your driving and looking peripherally in order to make a left turn, as an example. eyes and brain accommodated quickly to that and I don't even notice it anymore. Your eyes will adapt over a short time to find the right location of the lenses to view through depending on the distance of the subject. Looking through a viewfinder has never been an issue, although you may have to reset the viewfinder diopter wheel.

Unfortunately, my brain does not readily adapt which is why I had issues with the older generation of progressive lenses. The question is whether anyone has experience with the 'new' generation and if they notice any difference in through the lens viewing.

I am scheduled for my pre-surgery for my eyes in October. Hopefully, surgery will be done before Christmas. I don't know what it will be like to see things clearly but I am looking forward to it.

Not sure what is a "new" generation vs an "old" generation.
My current glasses are two years old and I'm due for new ones, as these are pretty scratched up and all the coatings are pretty much gone. I get mine at Costco and have never had a problem.
Seeing through the view finder has never been an issue either.
Even when the diopter has moved, I don't worry about it, as my auto focus is doing its job properly.
I'm surprised you mention peripheral vision, since that seems more dependent on the frames than any other factor.
As someone suggested, make sure they can be exchanged.
Good luck. ;-)

David, I assume you are talking about corrective to eliminate wearing glasses?
I also assume you have researched it to death.
After seeing what a friend of mine goes through, I, personally would never do it. I don't need glasses to see close, such as read or do intricate close work. After his operation, yes, he could wear cool sunglasses, but it destroyed his close vision and is almost blind without reading glasses. He has to pull them out just to count change at the store.
I guess for me, my close vision is WAY more important than my far vision.
Millions have it done and are happy, or at least say they are.
After reading Into Thin Air, it's not for me! Good luck. ;-)

I agree completely. I have been wearing progressives for MANY years. I have had no problem reading, looking through my camera viewfinder, driving, watching TV or working on my computer (Excel spread sheets, etc.).
Make sure the optician measures properly for where you will focus. Also, do not allow the optician to push the glasses up on the bridge of your nose prior to measuring. The blasted things will NOT stay there in actual use. Put the glasses where they will normally sit on your face, and THEN have the optician measure for focus.
Good luck and let us know what you decide.
Mike

Actually, the older generation of progressive lenses do have the need to look through the center of the lens for acuity/sharpness with edges that appear soft or out of focus. That causes me (and many others)peripheral vision issues. The newer generation extends that area of sharpness well into the edges and just wondering if any out there have them and see the difference.
