ugh... progressive bifocal lenses and high astigmatism Login/Join

Hi all,

Here I am typing up this post and my eyes are going bonkers. Forgive any typos. I have a high astigmatism in both eyes (+4.5 CYL). My optometrist recommended I get bifocal lenses for reading since I have started to strain a bit. I have 20/15 vision using my normal distance Rx. Also, due to my high CYL value I always get a high index lens (1.67) and have 2 base curve. I also have relatively small lenses, again due to thickness at the edge.

So I picked up my new progressive bifocal lenses today. First of all, the edges of the lenses are basically twice as thick! That is not what I was expecting due to still using 1.67 high index glass. This is also my first pair of "digital" lenses. These progressive lenses have the top 1/3 for distance, the middle 1/3 for about 21" away, and the bottom 1/3 for reading. Well, I work on a computer all day long with the screens at greater than arm's distance away (about 2.5 feet) and I must look through the middle 1/3 of my glasses about 95% of my life because I can't see crap.

The computer screens are blurry, and when I move my head and eyes I get a huge fishbowl affect. The optician did tell me some of this is normal when transitioning to progressive lenses, but this is just awful. She admitted its worse due to my specific Rx having so much CYL.

She asked me to try these out until Monday and see how it goes, but I definitely don't foresee myself keeping these. These are driving my eyes nuts and I can't focus on anything while working and typing. What are my options? I feel like all I really need is the lower 1/3 of my lens for reading and everything else should just be my normal distance Rx. Unfortunately they don't make no-line bifocals for that. When I put my single-vision Rx sunglasses on its like my eyes just relax and I see perfectly. I want that back for my everyday glasses.

Anyone who may have experience with this situation I'd love to hear your suggestions. Thanks!

Chris

I got talked into a pair about forty years ago,supposed to be better than sliced bread.
Walked out of the office and fell of the damn curb.
Went right back into the office and showed my ass as well as my skinned arm.
They were re ordered in the way I had requested in the first place.

Same boat here with the astigmatism. I tried them and did not make it a week. Thought I was going to wreck the car. I too spend most of my day at the computer. What I ended up doing was getting a set of bifocals set up for the computer/desk use. Top is focal at my normal distance from the computer screen and the bottom focal at the keyboard/desktop distance. I wear these 90 percent of the time. They are decent for intermediate distances but not long distance. I also have a set of bifocals for distance. Top is for the far distance - road signs, TV across the room - and the bottom is dashboard distance - I use these for driving. My sunglasses are a trifocal, top distance, middle dashboard, bottom reading. I always have to have the eye Dr adjust the prescription on my "computer" glasses because the normal prescription they want to make is never correct for the distance that I need for the computer and keyboard/desk reading.

Sounds like you might need a dedicated pair for computer use. There are lenses designed for just such things.

Also sounds like you should talk further with your O.D. AND optician ( how much experience do they have/ is the optician ABO/CPO certified?) about your expectations and they can help you with any reality checks.

Progressives are pretty impressive- when they are used for the purpose for which they’re designed. It does take at least a week for your brain to adjust to the new norm.

You also may want them to look into the lens material if the edge is that thick- another lens material may work better, the edge could be beveled, or hidden in the right frame.

Thanks for the replies so far. I do wear a relatively thin metal frame which I've had for several years. But it may be time to get a new frame, perhaps a bit thicker. I do like these, though.

I just took a few measurements:

Distance from eye to computer screen: 33 inches
Distance from eye to keyboard: 22 inches

I will give these new lenses a few days, but I think I'll need a different solution. Perhaps a pair of dedicated reading lenses with normal lined bifocals, and pair of standard distance vision lenses for everything else (computer work and everyday).

And I think I need to reduce the thickness any way I can. The thickness issue only occurred with these progressive bifocals.

I have multiple pairs of single vision:

1) Polarized, tinted, distance Rx for driving (day) / sun
2) Transitions, distance Rx for driving (night) / sun
3) Transition, mid Rx for around the house (watching TV, cooking, yard work, etc). Not ideal but can be used for driving and for computer but not for reading.
4) Transition, near Rx for computer and reading.

I think at some point I will get clip on frames with distance Rx and then the clip on will have Rx to makes the glasses effectively mid Rx or near Rx.

Multiple pairs of glasses has been my solution. Tweaking the computer print helps as well.

I had the same problem as the OP as did Mrs. Flash.

Our solution: MonoVision. I've been doing it for around 30+ years now and she's been doing it for around 25.

Eliminates all the bifocal/multifocal problems. It also eliminates master eye problems when you're shooting as a bonus.

Progressive lenses with the close-up in the bottom didn't work for me either. I was able to get used to everything looking like a trick mirror, but a lot of my work requires looking up at close objects, for example under a dashboard. I just use cheap "reading" glasses for this kind of work now.

I have two pairs, one for computer work and another for everything else. The computer glasses are coated with some protective lens to help reduce issues with looking at screens all day. Moving the center up and wider made all the difference no longer do I have to tilt my head up to read.

Neighbor has Nikon/Varilux progressives, he says they have a wider viewing area in each section, no longer does he have to move his head as much to read and see things. Of all places, Wal-Mart has them, Sams and Costco do not. They are not inexpensive.

One other option, years ago I had laser surgery to correct my astigmatism, basic vision was pretty good the astigmatism was the problem. was not too expensive, both eyes done, didn't need lens again until I hit 58 and I would have needed them anyway.

You might check to see if you are a candidate for Lasix eye correction of just the astigmatism. That would eliminate a lot of your issues with corrective lens.

At age 65 I got my first pair of progressives about 6 months ago. I expected problems but encountered none (I too have astigmatism). It is great to be able to see the dash and road clearly while driving. I do have single vision computer glasses, no way I am going to crane my neck to peer through the lower portion of the lenses. My skeet glasses are single vision (distance) as are my sunglasses.



Let me help you out. Which way did you come in?

There is more to it than just the prescription, although with the amount of cyl you have the Rx is a pretty important part of the overall solution!

With progressive lenses, *and your Rx in particular* it is *absolutely critical* that the measurements of seg height and PD are *exact* and that they were taken with your frame worn as normal and with your frame adjusted as normal AND with your head held in your normal posture. Absolutely critical.

Assuming the Rx is correct AND it was fabricated correctly AND your measurements (as specified above) were correctly taken AND the lenses edged into the frame correctly AND the lab did not mis-adjust the frame...it is almost a certainty you will adapt to the new glasses IF you can do three things:

1. Wear them. This means don't switch back to your old pair or your contact lenses, etc

2. Point your nose at whatever it is you're looking at-i.e. computer, roadway, television. You will NOT be able to see across the whole computer monitor-you WILL have to turn your head and NOT your eyes

3. Look DOWN with your head when going up and down steps, stepping over trees in the woods, etc. This will prevent you going head-over-heels!

You should be able to look straight ahead at your monitor and find a zone where it is clear by tipping your head. If you need to turn your head one way or the other for each eye to see the monitor clearly, the lenses are not centered to your PD. This would need to be resolved with a remake.

My little lizard brain couldn’t adapt to the progressives my eye doc ordered for me....

After several weeks of back and forth I now have “olde” style bifocals.....the kind with a line in them.

Worked the very first time and I haven’t fallen or wrecked due to them

I prefer lined trifocals for general purpose glasses, and I use lined bifocals, without the intermediate segment, for sunglasses.

I also use lined bifocals for desk work, with the upper portion for intermediate distance (computer monitor) and the lower portion for near work, like reading.

An optometrist I knew, who was a pilot, made quadrifocals, with a segment at the top of the lens that was just right for the switches above the windshield in some airplanes.

They may not have been made correctly.
My situation is similar to yours; when I got my first progressive bifocals about five years ago I had the exact same problem with seeing the computer screen.
I went back to my optometrist and told him the problems.

He had a guy in-house that made lenses. After my complaint he sent the prescription out to a lens making company.
The lenses that came back were completely different in that I could see exactly the way I needed.
Same prescription, two different executions.

I had the same problem as you. Unfortunately, the solution is going to be costly.

Years ago, I got my second pair of progressive lens and driving away from the store, I had the same problem as you described. The one third window was very narrow and my head was bobbing up and down. I returned back after a few days with my complaint.

In an effort to save me money, they used a cheaper lens. I said I want the same kind of lens I had before. The guy confirmed it had the widest window available.

The brand name is Varilux. I just googled it and it looks like they have different types under that brand but beyond the name Varilux, I can't help.

You honestly might do better with a lined bifocal but I wouldn’t give up yet. Make sure you have a high end progressive lens that’s fit right and a good Rx. Then wear them nonstop for a week or two.

O.D. here. Good luck.

I switched to progressive lenses years ago. Would not go back either. The getting used to/learning curve was awful. Fell down a few times. I just stuck it out and adapted.

Thanks for the replies, everyone. Especially the Optometrists!

I am going back to my Dr today to discuss the best path forward. The extreme fisheye is bad. Over the years I have adapted to edge distortions fine that are inherent with my Rx, but this is too extreme for me. Also, 95% of my daily life is well-served with single-vision lenses. I'd say maybe only 5% of my day is reading anything up close (on my phone, etc). I think it's best to have a main Rx that works best for 95% of my life and then come up with a specific solution for the remaining 5%.

Maybe a dedicated pair of bifocal glasses for longer stints of reading up close, or even a set of clip-on reading lenses. Not sure if that type of solution exists. Again, my multiple computer screens at work are 33" away from my eye and the middle 1/3 Rx in these progressives does not work for that. It's blurry, and no amount of adapting will change that since the middle Rx is specifically for 21" distance (according to the optician). I also find myself naturally watching TV in the evening through the middle 1/3 of my lens. Again, not good. Additionally, I find I naturally move my eyes all over the place without moving my head in most tasks I do every day so that's problematic. Even tasks like preparing dinner I have to look through the top 1/3 of my lens to see. Not good.

Thanks again for all the replies. I'll keep you updated on the solution. I realize that I've only had these lenses for 24 hours, but I do not think progressives will work for me given my daily needs.
