Have they given me the wrong prescription??

cantdecide

I picked up my new glasses and sunglasses Wednesday afternoon from a well known local independent optician. I had always previously gone to Specsavers or Vision Express. I've worn glasses 25 of my 27 years.

I broke my 2005 glasses a few months ago and went back to my 2000s until funds allowed. He performed my eye test and tested my old (2000) glasses and told me my new ones will be virtually the same. These ones were quite scratched and dulled.

I knew the minute I put them on that there was something wrong but I thought 'say nothing, the old ones are so scratched it's going to be a shock to the system- I'll get used to them'.

I wore them at home that evening and thought the same but put it down to adjusting to them. I wore them to work yesterday. I work with computers and within a few hours, I was literally cross-eyed. I suffered a cast (?) in my eye as a child but there are particular circumstances that bring it on from time to time.

I know I'm having to strain and focus too much and there is a definite difference in the strength of my new and old glasses. I rang them up and explained my observations(:rolleyes:). I wasn't expecting an ambulance to be dispatched but he didn't sound particularly taken aback. He told me to come in tomorrow and they'll get to the bottom of it.

Is this something that happens often??

Thanks, Donegalfella.

I'm back on the old ones already. The new lenses are almost the same in prescription, spec and shape as the old ones so of all the times I've got new specs, this should have been the easiest transition...

Eh that does happen with a lot of patients try working in an opticians and you'll understand. Remember these people trained in optometry and kind of know what they are talking about.

If a person has accepted a change in their prescription during the eye test it can take a week or two for the brain to accept the change.

In your case cantdecide if you feel it's not right then it's not right. Go back to your optician to double check the prescription. If the prescriptions are ment to be the same then you shouldn't notice any difference.

BTW did you go from standard sized lenses to thinned down or other way if so this can sometimes be hard to get used to initially as well

They are meant to be the same prescription as my most recently worn glasses (which are old spare glasses bought 8/9 years ago). The lenses were thinned in both these and my new glasses.

The lenses in my sunglasses are not thinned but I can see that the prescription of my new glasses and new sunglasses are the same and they are both definintely weaker than my old glasses. I'm heading in to them at 3:30 and I'll let you know wath they say.

Good call hope you get sorted out. Interested to hear the outcome

First things first
-You need to get Specsavers to tell you if the ocular centres in your old glasses is the same as the new ones, this may sound ridiculous but sometimes if two different people took them and there was an indiscrepancy between them it can cause problems. Trust me, ive come across this on more than one occasion where the patient has had glasses made somewhere else and the PD was taken incorrectly and glasses made up but even though our PD was the correct one the patient had become accustomed to the older PD and found it more comfortable.

-secondly, you said your lenses were thinned down in both, you need to have them check and verify if your old lenses were Aspheric or Spheric, if they changed you from spheric to aspheric then you will have problems adjusting to it, no matter what people tell you there is a world of differance between the two that im not going to get into here, but having studied them for the last three years you can take my word for it.

You don't need specsavers to tell you if your ocular centers are off your new optician can compare the new versus the old job. I've seen it recently with a glass lens patient who had his pd tweeked outwards to lessen the outer thickness on his job. We set it correctly with his new 1.74 lenses but he couldn't take to it as he was used to the old PD and he didn't like the thickness. We didn't cop he already had glass lenses. But when he got glass and set to his old PD all was ok ah well we lived and learned.

Like I said Donegalfella work in an opticians for a while before you can pass an honest opinion on what happens behind the counter you might then appreciate then how difficult it is to get every job 100% right or are you one of the sheep who believe everything they hear and see on the radio and tv

Sorry i had actually misread the post i thought the Px had actually gone to specsavers for the glasses which is why i said to go to specsavers to verify the ocular centres

Very possible they got it wrong. I went to a big chain just over a year ago for the first time to have my eye’s checked and if needed new glasses. They checked my old glasses, did the test and it turns out I needed a new px as I expected. When the new glasses came in the minute I put them on I knew something wasn’t right but put it down to the normal new lens syndrome (been wearing glasses for about 22years) a few days later my eyes just could not take it. Went back in and they sent the glasses off to get redone as they were wrong, why they didn’t check this in the first place is beyond me. Came back to collect them popped them on and again thought something was up. Gave them a try for a few days and still my eyes were getting very strained with them.

I got a write out of my Px from the chain and got an appointment with my old optician (long drive away) he did the test and I asked him to just write out my Px. Then I produced the Px from the chain to show him to see was there a difference and there was. I wont go into the figures but the one eye was over prescribed one under (by more than 1), the prism was reversed and something else that escapes me right now was arse ways. When I got my normal opticians to do up my new glasses I popped them on and did not have a single problem with them since.

Worst part was while using the chain stores glasses I managed to do damage to my car as a result of the fupped up Px and not judging distance right. My own fault in one way, theirs in another.

Calm down.

I went back to my optician last saturday and he re-tested my eyes. He checked the glasses and told me was still happy with the numbers.

When I met him originally, I clearly remember him telling me that the new ones would be almost the same as the old ones I brought into him. This time, he corrected himself and told me 'if I said that before, I was slightly mis-leading you', which was odd, I thought. He said that there was a noticeable difference, especially in my weaker right eye which he has prescribed a weaker lens this time.

He told me 'don't worry, we'll get you sorted one way or another' and said that he was still happy with all his numbers and that I was in fact given what he requested...

He told me to give it a week or ten days and if I'm still not happy, the only course of action would be to go back to my old prescription. I agreed in the hope that it was in fact still a matter of geting used to them. I wasn't impressed at the idea of going back to the old prescription- I wasn't having problems but I wasn't 100% happy that they were right, either. It doesn't sound completely scientific, either, IMO.

Several times this week, I've had my eyes going crossed (my weak right eye moves to the LHS of the socket) and a general feeling of strain/ headaches. This was only whenever I was doiong a session at the computer. When I cover my left eye and try to see with the right, I seem to have a sort of blind spot, where I can't look directly at text- I must slightly avert my eyes??

I think it's time for an second opinion...

i really think you need to confirm with your optician if your lenses are now aspheric as opposed to spherical. In my professional opinion it sounds lik that could be past of the cause and the most likely situation if he's happy with your prescription an the glasses

Thanks:)

Forgive my ignorance but why would I be one and not the other and how do I broach the subject without insulting him? Is this not a grave and fundamental error that he would have re-checked when I got my sight re-tested??

No no not at all, it is in basics, a property that a lens can have.
An Aspheric lens makes the apperance of the lens, flatter and thinner even more so than a thinned down lense.
And this "aspheric property" can be used alongside "thinned down" lenses to give them an even better and thinner finish.
When you get into high index lenses ie, thinned down lenses, your optican has the option of Spheric or Aspheric. Or in some cases they only come in an aspheric lens for example the 1.74 lense-which is the thinnest lense you can get in plastic.
The difference, again basically, between both is that the Spherical lense:

• Firstly, will be more comfortable to look through straight away
• Secondly, the perscription all over the surface of the lens is your prescription (give or take tiny amounts-maximum generally 0.12 difference at any point)

wheras Aspheric:

• can feel very uncomfortable and your eyes and brain need time to adjust
• and most importantly, your prescription is exact at one point in the lense, where your eyes see through, so you would need your PD to be absolutly perfect, you would require heights in the lense if your eyes do not sit on the exact horizontal centre point of the frame, as other than this exact point on the lens your prescription changes, not a whole lot, but more so then on a spherical lense, which is wahy they can be made thinner and flatter-they do not need to make your prescription for example +/-5.00 all over the surface of the lense like on the spherical lense

Many many people get on fine with Aspherical lenses, but there is a small percentage of people who just cannot tolerate it, i have some across it a few times, especially where people wore spherical lenses beforehand.

Now i dont know if this is the problem that you are having with the glasses but i think it may be one very possible answer.

Since I started this thread, I had my car valeted and on top of doing an amazing job, they found my old prescription sunglasses from 2005 that were in good condition. Good lads.

I spoke with my optician today and told him how I'd tried these at work. I have given his new ones a considerable trial for over 2 weeks now and the sunglasses immediately clicked into place for me.

In my new glasses, my left eye was prescribed as 5.25 and the right weak eye was 6.5. He tested the sunglasses and they came out as 6.25 and 6.5. He did some tests with the 'goggles' and giving 5.5 in my left eye and placing another +1 lens over it made it no clearer, but considerably bigger. He went on to tell me a bit about accommodation and convergence which he reckons explains why my right eye was turning in.

He apologised (none was necessary but he did), and told me that what I had said makes sense. He is ordering in the new lens for my left eye and it will hopefully be sorted by Saturday. If I am happy with that, they'll switch the ones in my new sunglasses.

Got the new lens fitted last weekend with the correct prescription and hey presto- sound as a pound.

Best glasses I've ever had.
