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 had my cataract removed 4 months ago from my left eye. Had the typical halo around lights at night while driving. I have never needed glasses to read, rather just for distance and that was not a big prescription. I thought the ophthalmologist and I were on the same page with his understanding that I wanted my surgical eye to be near sighted like my right eye is, like my vision has always been all my life. Well..now I have to close my left eye to read. Distance is great out of my surgical eye, I still wear glasses to drive for my right (near sighted eye), but NOW I have a problem reading my cameras histogram and camera settings with my surgical eye. Right eye is getting worse and will require cataract surgery, I am told a corrective near sighted lens can be inserted in the other eye (which I thought was going to be done in my first eye originally). These mean I will have one eye near sighted and the other far sighted. Not happy...so to end this long response, make sure you doctor understands thoroughly what you want. I thought I had this understanding with my doctor.

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.

I've been using them for 10 years and have never see any softness. New users have complained of some parallax distortion affecting extreme peripheral vision a bit, but most people usually adapt. Mine are great. They make me feel like I have normal vision no matter what I'm looking at. I usually forget I even have them on.

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.

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've used progressives for the past 7 yrs - no issues at all, other than having to remove them to use the preview screen - I am nearsighted and my close vision has not been affected that much so I see small things better without them.

I wear progressive trifocals. Be aware that you won't like them at first. There is a 'getting use to' period of 2 - 3 weeks where you will trip over your own feet and be frustrated with them. Once your eyes and brain adjust to them you will probably love them. I am not aware of the progressive lines. I automatically adjust my head to view far, midrange and close up. I have no problems using my cameras.

I've been using what I think you are refering to for a couple of years now. I have an extremely good display screen equipment setup at work with my two screens being not far short of 1m away from my eyes, whilst paperwork lays on the desk and I flit between the two seamlessly. I still take them off for a stroll up the office and don't need them for camerawork (inbuilt dioptre is sufficient for me) or driving / watching TV etc.

If you've got confidence in your optician and can afford them I reckon they're worth a punt. You may find a lens manufacturer has a sample you can try, always worth asking.

NB! My prescription is for a low dioptre bifocal and was especially suggested by an optician we have used for the whole family for 20+ years as a solution to a particular problem I was having at work. At home, where I do not enjoy such good DSE layout a single lens prescription is good for everything.

Like any other product in this world there are the bad, fair, good, better and best. Progressive lenses are no exception. There are over 600 progressive lenses on the market today. Then there is standard manufacturing and digital (free form. Just because a lens is digitally manufactured- doe not make it better. The lens design is important- a lousy design manufactured digitally, is still a lousy design. Some of the best progressives out there are Varilux (and they have many different designs Comfort, Physio, "S" series) Zeiss, Shamir. There are also progressives that are for general use and specific uses. For office work , there are progressives that are more for intermediate and near distances than for far distance. You should wear your glasses as close to the eyes as possible for best results( think about looking through a key hole- your angle of view increases as you put your eye closer and closer to the key hole. Do not for get to get an anti- reflection coating (crizal alize or saphire- being among the best). It does for your eyeglasses what it does for your camera lenses. You should also consider Transitions - the lenses turn darker when exposed to UV (remember car windows block UV - so the lenses will not turn dark in a car. The way you use a progressive is- point your nose to what you are looking at then raise or lower your chin to focus. The average time to get used to them is about 2 weeks- some people put them on and have no issues from the get go - others adapt after a month thus an average of 2 weeks. The more you wear them the better chance of adaptability.

One caution. With progressive lenses, you must make sure you are looking entirely through the distance lens upper portion. If your head position is raised so that the transition begins to change into short distance correction, and you are using manual focus on your camera, you can end up with out of focus shots because your camera focus will compensate for the improper distance.

Also, I would never consider transition lenses while shooting which would cause problems "dimming" down the viewfinder image and/or distorting colors.

Been using them for about 43 years - don't like them; my eyes require trifocals but cannot handle trifocals. I have to continually search my head up and down to find the "reading spot". For casual reading, for example - store labels, they make due. For serious reading - a book, or the computer they not good because, again, I have to find the "spot" and freeze my head at that point. I have a second pair I use for the computer and reading. When I leave the house the progressives go on, when I return home, the readers go on. If I take a book to a waiting room, the readers go with me.

About two years ago my optician incorrectly made a pair of progressives for me and suggested I try them before making a bi-focal pair. I had them for exactly one day and they absolutely drove me crazy, especially while working at the computer. Needless to say I went back to what I was used to.
I do know others who love progressives.

This new digital lens technology is definitely a huge improvement. They are only $100 more and well worth it.

I have always had varilux, my wife has varilux in a stronger prescription and has tried bifocals, she could never adjust to the line, caused her to almost fall a couple of times, I suggest you move to GOOD progressives there are several brands, some with wider viewing zones, at least according to the "experts" we've consulted.

I've been wearing "progressives" for a number of years. My presbyopia requires that I have them to focus on anything close. No issues with distance vision. I do remove my glasses to look thru the viewfinder & put them back to view the LCD screens... Took a bit of getting used to when I first got them, but no issues now. I've had bad hearing since birth (aids in both ears) & my wife has trouble with distance vision. So, I am her eyes & she is my ears...

So far so good for me. Much better then that terrible line in the middle of the lens.
