Problems with Keratoconus and New Glasses

Hi all my name is Anthony, I am from London, UK

I wonder if anyone can help or comment on my New Glasses problem, I recently
had a new eye test and replaced my old glasses with a more fashionable looking
set, however upon wearing the new glasses I found vision through the glasses
was not correct, things look "trapezoid" my TV, Computer Screen, just about
everything.

I went back to the store and they said the Lenses are cut wrongly, so they
will redo, I waited a week and returned and found exactly the same problem,
at this point the Manager came over and said how about you try a standard
Lenses instead of the Zeiss Lenses I paid for, again another week.

Yesterday I collected and again I am still seeing the "trapezoid" effect, the
optician said perhaps I just need to adjust,.

My question is:

Am I being to eager to get use to these, will my eyes adjust or is there
something wrong.

Please note it has been about 4 years since my last prescription and
apparently the jump in prescription is high.

I also have "keratoconus" in both eyes as informed many years ago

This is my new prescription:

Sph - Right: +0.25 Left: +0.75
Cyl - Right: -1.50 Left: -1.75
Axis - Right 57.5 Left: 102.5

Can anyone help??

Hello Anthony and welcome to the forum.
I hope one of the optometrists who post here will be able to give you a better answer than I can. Sometimes it does take the brain a few days to adjust to a very different prescription so you may find things revert to normal. Or it's possible that you've reached the stage where you'd get much better vision with contact lenses rather than glasses. If your optician isn't an expert at fitting KC lenses, you could get your GP to refer you to a hospital eye clinic where you'd be given more options.
Good luck
Anne

I am afraid any answer that I gave would be speculative. However, there is sure to be somebody qualified to answer your question along in a moment.

Welcome to the forum

It takes roughly a week in my experience for the brain to adjust to a new presciption strength of glasses or contact lenses [once tolerance is built up] so if it's still trapezium after a couple of weeks then maybe it's time to look at contact lenses

Just as a follow up,

The new glasses seem to be geting better and the Trapezoid effect is improving however when I take the Glasses off now I see the Trapezoid effect in reverse.

Is this right, am I damaging my eyes?

This si worrying me as eveything seemed fine prior to being told I need to wear glasses full time, in honesty I never wore my old glasses so I guess I am to blame.

I am not sure about damaging your eyes so much as your brain having to work a little harder at interpreting the changing information that it receives from your eyes.

Still, it would e worth mentioning to your eyecare specialist.

Hi Anne

I'd be inclined to agree with Andrew.
When i take my contacts out everything goes blurry for about 30 minutes until my eyes adjust to my glasses again.
But no harm in asking you Optom about it just to be safe.

I’ve also got some glasses with a trapezium effect. I wear contact lenses most of the time but I do have two pairs of back-up glasses which give me some sight. The older pair aren’t much good at a distance (but a lot better than the naked eye) but I can use them for the computer and to read. The newer pair are stronger so they are better at a distance but give too many multiple images for reading and computer use so I rarely use them.

The close up vision does not only have too many multiple images but things are a strange shape. A sheet of A4 held at reading distance appears to be much narrower at the top than the bottom. If I put the glasses on upside down (ie the right eye is looking through the left lens and left eye through the right lens) the A4 sheet appears narrower at the bottom than the top. But if I only look through one lens at a time the sheet of A4 appears as it should! No wonder I never got on with these glasses.

Hi Anthony.

Well first of all, it sounds like your optom has looked after you quite well - not many would straight away opt for two reglazes without a good period of adaptation after such a change in prescription!

Do you know what your previous prescription was? I imagine that there has been quite a large change in 4 years, with keratoconus. Provided the glasses have been made up correctly (and it sounds like this has already been checked a few times), then it most likely will just be a period of adaptation. It is quite common to experience sloping lines like what you have described, when there has been a change in the cylinder power and/or axis.

I'd say give yourself a good 2 or 3 weeks to adapt to the new spex. It's what I always advise my patients. And don't be tempted to switch back and forth between the new glasses and the old ones, as this will just make things more difficult. If still a problem after a couple of weeks, it might be worth going back to where you got them. They may recheck the prescription in the testing room if they are still at a loss as to what's wrong.
