Can progressive lenses or trifocals be made with different "breakpoints"?

This may not be specific to glaucoma but it sure affects my eyes getting tired, leading to double vision in the evenings.

My failed cataract surgery (leading to vitrectomy and sulcus lens) was more than a year ago. I haven't had glasses that work right since then: I'm still using my progressives from before my cataract surgeries.

I have a new prescription that works really well for distance (super sharp - love it for driving or watching a distant TV) and very well for hand distance (phone held close), but the middle distance is a mess. With progressives the "sweet spot" for that distance is way too small. One optometrist said "Oh, so you need trifocals," and I got some, but again the band for that distance is TINY, nearly impossible to use.

Is it possible, at any cost, to get progressives or trifocals made that have a wider band? Or SOMETHING?? (I think "breakpoints" is the word for where and how sharply the prescription shifts but that might be wrong)

It drives me nuts that the glasses that work best for me are the ones from before either cataract was done!

Dave, I recently got a new prescription for progressive lenses after my eye settled down from a vitrectomy and cataract surgery. I went to a highly recommended optometrist for the prescription but couldn't find frames I liked at her optical shop. I found ones that I liked at a "Mall" optical shop called "See" which has locations at Malls around the country. I wasn't overly impressed with the optician at the Florida store I went to, but the glasses work well so the company did a good job of applying my prescription. One of the options he offered me was getting a bigger visual field for the distance part of the glasses (@ $100 more). I didn't go for it, but apparently, this is available per your question, at least for progressives. I did ask him if it was possible to get 3 visual fields in a progressive lesn (distance, reading and computer) and he did not recommend it. So currently I have one pair of glasses for distance and reading, and another pair for computer and reading. There is a See store in Metro West Boston at the Natick Mall, however, I wouldn't be surprised if there is one closer to you. Hope this is helpful.

Thanks, Leslie. I have to wonder: why is it that my old pre-surgery progressives let me see tolerably well at any distance, and the new ones I got didn't? I tried them for two weeks and it was crazy-making.

Then from the same prescription I got a pair of bifocals and a pair of trifocals. Both are great for distance, and are usable (sorta ok) for phone held closer than I usually do. For the trifocals they didn't add a band - they removed a 1/4" slice from the close-up segment. What the heck! Is this normal? Can I find someone who'll make them differently, custom, or is it all so automated that I can like it or lump it?
