Any opticians out there?
Discussion
Recently had my eyes tested, need specs, got them and they were rubbish, wifeys ones are perfect for driving and watching the telly. Went back to opticians who tested me again and said, yes, your eyesight has deteriorated so new prescription on order. Thing is, he said 'wifeys glasses may seem better in the short term but we go for the minimum optical change that will show an improvement otherwise you'll cause eyestrain.
This sounds like nonsense, surely if wifeys glasses are stronger and I can see easier then I'm not straining my eyes.
Is this another way to get me to order more prescriptions?

968Wifey's specs may be over-correcting. Assuming you're short-sighted (can't see distance), you want the least power lenses that will allow you to focus on infinity with your eyes fuly relaxed. If your lenses are more powerful than that, you also make your near point further away, making reading harder.
IANAO
Interval between tests?
Sounds a bit like an excuse for a wrong prescription / incorect dispensing / incorrect lens cutting first time.
Do the provided specs match the first prescription? If so, why now the change of prescription on a retest if not too long apart.
On the other hand I've heard the minimum prescription thing before.

2 months and the scrip had changed. I have reading goggles too the scrip hasn't changed for them

Chanel Number Grimsby Docks methinks.
If you tilt or move the specs does the image get clearer?
Second opinion sharpish, get specs checked out to first prescription, and that the optical centre of the lens is correctly positioned in front of your eyes.
Doesn't sound right to me.

Problem is that the "least power required" varies on a continuous scale but lenses come in discrete steps, and they tend to give you the standard lens which is slightly weaker than required, rather than the slightly stronger one. This means that the defect is not fully corrected and objects at infinity are still not sharp, which is a bummer for driving.
Our illustrious FiF recommended to me a good optician in Halesowen who were most helpful and gave me the slightly stronger lens, resulting in the best pair of specs I can remember having. The near point effect is minimal, and in my case irrelevant since I can focus OK up to a couple of feet away and always take my specs off for reading etc. If you're not put off by the distance I can dig out their details.

If this was the case the everyone would have telescopes. If you have heart tablets would twice the dose make you twice as healthy?
Also if your prescription has altered in a couple of months is there any underlying problem, could you be diabetic etc?

y'know that's exactly what I thought, I've worked with vision systems and it seemed the image was sharper but somehow off centre.............they're going to give me new ones so I'll see then

Blimey, that's a good answer!
If you're shortsighted, you want to provide the least myopic correction you can get away with, so that the eyes aren't accomodating all the time, to get a clear image, indeed in the short term it's ok, but after a while, it will be uncomfortable, and cause headaches.
I've been wearing glasses since I was 12, I have a squint (one eye pointing the wrong way), and as as result, long vision.
I've always had weak prescriptions. The general concensus has been that my right eye was weak, and that by making it strain a bit, it would stay a little bit stronger. I had prisms in my lenses for years, and even with plastic lenses they were getting bigger, and heavier.
That didn't stop the problem from getting worse over the years, and about 4 years ago I had corrective surgery on it - not laser surgery, but actual pulling back of eyelids, cutting through membranes, and slicing and stitching of muscles! The surgery pulled the eye back into line so that now I just have glasses to correct the long vision. The double vision is only present without the glasses when I try and focus on things.
Bad thing is I have a slight droop in my right eyelid now which nobody warned me about. Still, at least I get to wear glasses with superthin lenses for the first time!

Sounds like you had an accomodative convergent squint, ie the eyes being long sighted would squint, and required hypermetropic correction to make your eyes point the same way. Squint surgery is a good way of realigning the eyes, but it's better done at a younger age, to allow the development of good vision in each eye.......Nonetheless, it's a good op and has done a great deal of good for you.

968, am I correct in thinking you are an opthalmic surgeon (sp ?) ?. Would you be prepared to answer some questions for me regarding eye sight ?. We were told my 4 month old daughter was blind, but we don't really understand what is going on as nobody has sat down and explained to us what the test they have performed (locally and at GOSH) actually mean. And we get conflicting anwers from her paediatric consultant and the opthalmist (?) who saw her, whom we have not been able to contact.

Of course you can..... Feel free to post or email me.....
I'm not a paediatric expert, but I do know a bit. It's surprising that they haven't kept you in the loop about what's going on, normally we are very very careful that parents understand what's going on. Perhaps you should contact the Consultant at your local hospital to ask him/her what is going on, and what the provisional diagnosis is?

Have a meeting with the consultant this afternoon. If things are still unclear then I will PM you. She has so many other problems and has been seen by so many doctors in numerous hosptials nobody seems to have the complete picture with regards to her eyesight. She is due to go to Moorfields in Feb, but for what we don't know. To be fair to the consultant and the local hospital they have been otherwise good, but the priority has been on stabilising her and getting her pain free so far.

It may not be easy to assess her vision, as she's clearly very young and has lots of other problems, which can all interrelate to her sight, particularly if the brain is affected. Let me know what they say at the hospital today. I will try to interpret for you. If you ask them to write down what they think the problem is, it might help.

if they were rubbish from the start its the wrong prescription in your glasses.
a good pair of glasses should be clear and comfortable the moment you get them. the best glasses are those that when you walk out of the opticians you think "since when has that shop been that colour?". personally, it sounds like the optician's tested your eyes and then went for a slightly weaker lense for the prescription.
i'm not sure if this is true - but the positioning of the glasses on your nose can change things. the closer the lense to your eye the weaker it has to be (i think) thats why there is a huge difference between a contact lense prescription and normal glasses. so if you have your specs too far down your nose then they could appear weaker.
