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.

Doc, Nikon makes lenses with a wider field of focused view.

It's obvious from the responses here that there are several variables. First, it depends on what correction you need - distance or close up or some combination. Second, it does matter how well your lenses are fitted and customized to your face and eye position.

I wear trifocals and while I hate the lines which look like smears of Vasoline on my lenses, at least I know where the lens correction changes. When using the viewfinder on my camera, I don't worry about being slightly down into the transition area. Yes, you need to adjust the diopter setting on your camera, but you should only do that when using the distance portion of your lens. If you are accidentally anywhere into the transition area (which happens in the field if you need to change normal body position for some reason) then your focus will not be "on." With transition lenses, you don't know exactly where that transition begins and if you manually focus a lot (as I do), you can get some fuzzy shots as your focus is compensating for your lens as well as the subject matter.

I wore bifocals for years and was never able to adjust to the older generation of progressive lenses. In the older generation of progressive lenses, the field of vision used to be very narrow and I had difficulty adjusting to the lack of peripheral vision. However, about 5 years ago, I was able to move up to the progressive lenses because the technology had advanced to allow for a wider field of vision. I no longer have any issues with peripheral vision. Now the technology has again advanced to something that they are advertising as "HD". This has made the field of vision even wider and emulates that which you have with your tri-focals. It is important for your optometrist to get the eye position correct so that your new progressive lenses will work in the same manner that your tri-focals now function. As others have stated, get your glasses made somewhere that has a good return policy. I've used both Costco and Lenscrafters and had no issues with returning glasses. I would recommend Lenscrafters for your first pair as their electronic method of measuring eye placement (they take a picture of your face with the new frames on and then electronically measure where your eye naturally sits.) is more accurate and will result in crisper vision with the new progressives.

This is also a good source of information on progressive lenses in general.I have been retired 6yrs and have no experience with this particular lens design,but it sounds like a great idea.

Made me dizzy... OK more than usual. Very distracting and eery.

When I first got progressives, I had to be careful operating equipment as my peripheral vision was off until I got accustomed to them...

I have had Photochromatic Transition lenses for years and they work well. These lenses darken in sunlight and lighten in darker areas.I needed new glasses and tried a new optometrist as my previous shop changed hands. The new lenses were considerably more expensive than my previous lenses. One presumes that where ever you shop for glasses that they use the highest quality lenses. There are differences just like the glass in camera lenses! The difference in the more expensive lenses and coatings was noticeable and I have not regretted the additional expense.

A very true statement.

I love my progressives BUT !!! I asked my eye doctor for glasses made just for using my laptop. I took it with me and she measured how far away I place the screen. My prescription is just for use with the computer so I was able to get the cheapest glasses Costco offers (no antiglare, etc).
When I put them on as I use the computer my brain goes "ahhhhh!" My eyes relax, I don't adjust the headÂ…I LOVE them!

Single vision lenses work great, but after presbyopia sets in at about age 45, the power is only good for a certain working distance and distance and closer vision will be blurred through thelenses.- I had a pair of progressive lenses made where the top was focused at about 24 inches and the bottom was for reading. They work well at the computer.

VERI-LUX PANORAMIC are the best Progressive, in my opinion. You can order them with UV, Scratch Resistance, Anti-Fog Resistance & Transition. Of course, these are not inexpensive. $500-$600, without frames. Ask and let them show you the difference. Have no trouble focusing. Used them for many years. Just ordered my 3rd pair. Good Luck BV

They are excellent.

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 worn trifocals for years also, but if your glasses have 3 lines they are quadfocals!

Really appreciate all the feedback and am going to try the new wide spectrum progressives from Lenscrafters where, yes, I can take me back if I still can't adjust. Note that each time progressives have, ahem, progressed, I've tried em and couldn't adapt. Maybe this time and thanx again.

The first time I had progressives it took me a week to "learn" how to use them. You will esp have trouble on stairs. You have to learn to move your eyes up and down to the correct part of the lens and tilt you head for cases where the eyes simply can't go far enough.
