I've been wearing occupational ones for reading and pc use for a while now and just got a new prescription. My first pair probably 10 yrs ago now had a problem where if I moved my head slightly all the image would distort with rectangles becoming trapeziums. The optician at the time changed the lenses and the replacements were fine. Second pair new prescription a few years later no distortion problems. Latest pair new prescription and new optician great straight on but even the slightest movement sideways creates terrible distortion. I complained and they have replaced them with better quality lenses (...?). Now these are much better but there is still some trapezoidal distortion as I move my head side to side. The optician said I'd get used to it and my brain would soon compensate as it probably had done for my previous pair. So my questions are, is he right? What's going on? Are there even better lenses that won't distort? He said see how you go with them so I'm giving them a trial for a few weeks but not sure what to do if I don't get used to them. Any advice, thoughts, etc gratefully received.

I wasn't familiar with the term 'occupational' but I think what you mean is intermediate distance vision lenses? An example would be reading glasses if you are long-sighted?
I swear by varifocals but they do require adaptation (no problem for me, but it took a couple of weeks for Julia when she switched to them). I now have varifocal polarising sunglasses and of course these work brilliantly at last since the OM-1 arrived

Will see if my daughter has any advice, she is an Optometrist and a big advocate of occupational glasses.
More and more people are requesting them, usually for an intermediate distance to their varifocals.
I have a pair set at optimum distance for my pc screen, great when I remember to use them.

I had the same problem a number of years ago, my glasses distorted at the sides and it was really uncomfortable using them. I complained and the optician (a very quick sounding company) told me the same thing that my brain would soon sort it out. I complained again with the same answer. The glasses were unusable so I ditched them and used my old ones for a while. I then asked around for recommendations and tried a different optician and have never looked back, the difference was amazing, the new glasses were perfect.Comment

I too have noticed this with my reading glasses. I had one pair that produced orange banding on one side of the screen and blue banding one the other side
They went straight back to Boots who swapped them for Zeiss lenses that are excellent!Graham

There are a huge number of threads on here talking about camera lens quality and most people recognise a difference between low-cost and pro-quality lenses. The same surely applies to lenses for glasses. There are good ones and not-so-good ones.
It's a cutthroat market out there to provide low-cost glasses and lenses and something has to give. I think quality control in the manufacturing process is one area some suppliers cut back on.Comment

Had a word with my daughter and short answer is return to Optician.
She did mention that Zeiss can work as a problem solving lens for axis issues.
Just my comments now, get the measurements checked and try to see their dispensing optician to get the fitting right.
One bit of general advice that when she told me made perfect sense.
When asked to hold up a sheet as you would when reading don't sit bolt upright arms outstretched holding it at a distance you think is the accepted norm
If you sit slouched book in lap do so and try to have a rough measured idea of distance before you go especially if its at a set distance such as a monitor.
Helps a lot to get the glasses performing as you would want and expect.Last edited by Tram; 12 November 2022, 05:40 PM.Comment

Passed on your thanks Phill, if you are not happy go back.
Even if the prescription is right poor measurement and/or fitting can make or break the end result.
Varifocals also work better for wearers who move their eyes rather than their heads when changing focus point -
Yes I realise moving the eyes is preferable and that seems fine vertically. However, sideways still introduces the distortion and also actually some oof. It doesn't happen as sharply as the first pair they sold me but it's still at a relatively small off axis angle. In comparison my old pair just don't seem to do this. As you say now I know a lot more I'll go back. Maybe now my prescription has changed a little this is the best I can get? We'll see.

I had a very similar problem when I changed from bifocals to varifocals. I persevered for a couple of weeks but couldn’t get on with them. I returned to my optician, a small independent who has since retired😩, and he explained that there were two main types of varifocal lenses and one of them suited a huge majority of spectacle wearers but clearly not me. He changed me onto the other type and my problem was instantly resolved. I’ve never looked back, best thing I ever did. I still use varifocals but I now also have a pair of single vision for use with my PC.Comment

You get what you pay for. I have top of the range Varilux normal varifocals which have very little distortion, and Varilux Digitime Near Ormix occupational varifocals which are superb. No distortion, and work well for reading and laptop at lower angles, with the the straight ahead perfect for a desktop monitor just beyond arms length.Comment

I confess that I use an inexpensive online specs supplier and they don't state the lens manufacturer but they offer tiers of quality and I always go for the 'elite' top category. These are freeform lenses that are custom manufactured for your prescription and the frames they need to fit to. I've always been very happy with them. I do get them fitted at the one store they have in the UK though - they mark blank lenses using the actual frames you've chosen and wearing by aligning your eyes. -

I wear distance glasses for everyday life all the time .. but have a different prescription for working on the computer .. for reading books or the i.pad just my naked eyes are fine , weirdly enough when I had my fall last month I couldn’t wear glasses for around two weeks and found that my distance eyesight was getting better on its own I.e watching t.v etc ??Comment

I have always believed that I should have only top quality lenses for my spectacles. Mine are Zeiss varifocals, with the prescription of the short distance/reading part closer than normal. Even so, I am content to read in bed without them. I pay about £500 for a pair of lenses. I get very slight colour aberration at the very edges if I turn away from what I am looking at and look sideways, not something I would do, except out of curiosity.

I agree Harold I'd have gone back to my old optician if we hadn't moved house. I went to the place that seemed to do the most comprehensive eye examination in the local area. The test was good but it seems like they skimp on the quality of the glasses. Well something is different at least. My old ones behave the same as you describe I can in the extream move my head and look out of the edge of the lenses with no discernable distortion and even no out of focus. The new ones distort and slightly loose focus with only a few degrees of movement. I said I'd give them 2 weeks to see if I get used to them but so far I definitely prefer my old ones.

I got a new pair of varifocals early last week and they still feel rather strange. I have to move my head up and down to change from close focus to distance and turn my head rather than moving my eyes from side to side. They are much better for reading than my last pair, though. However I am in the throes of a PVD (Posterior vitreous detachment) at the moment and having to contend with floaters, blurred cobweb shapes and bright flashes of light at the periphery of my vision, so moving my head a bit is the least of my concerns at present.

Hope they can sort out your detachment Ron, that doesn't sound good. I got a bit of a shock too when I had my recent examination, apparently I've started the early stages of AMD. Apparently it's not bad enough to affect things yet but definitely something to monitor. -
Thanks Phil. Apparently PVD is quite a common consequence of ageing and is usually not too serious. It should sort itself out after a few months. I have an excellent optometrist and he has even given us his home telephone number in case we are concerned at any time and need reassurance. I can't ask for more than that. I hope your AMD does not progress too badly and they can keep it under control. My mother had it and it is not nice.

I had the same symptoms as Ron/Olybirder. They came on suddenly in Dec 21. The condition was also diagnosed as PVD which was better than a detached retina which may lead to permanent loss or poorer vision in the affected eye if not treated promptly. In my case, no further treatment was required. The symptoms eventually diminished.

Phill D How are you getting on with your new glasses now after a couple of weeks have gone by?Comment

Thanks for asking, I'd say they are sort of okish. Still getting the distortion and slight oof as soon as I look even slightly away from straight ahead. Just tried my old pair in direct comparison and they are much better Maybe not quite as sharp straight on but they are distortion free and sharp all over. Between the two it's like looking through a keyhole Vs a window. Much more relaxing with my old ones even after over two weeks with the new ones. So I'm going to see if I can get an appointment next week.
