Which is better for children's myopia?

[Sunshinedayy]

Is an accurate prescription better or a full prescription?

Just that really. I know under correcting and over correcting are bad but is there a diffrence between accurate prescription and full prescription? If so which is better for children's myopia? Or are they interchangeable?

DD (9) has just been offered these. Glad to hear a good review thankyou

Could you correct the person who asked the question, do you think? The OP asked a question, I answered it to the best of my knowledge. Funnily enough, we both managed to do this without being utterly fucking rude. Incidentally, there is a distinction in optometry between an accurate prescription and a full prescription. What, you think the OP just dreamt this? So you're wrong. Rude, and wrong. And don't @ me again - you won't get a response.

Replying to the above comment, which apparently I’m not allowed to reply to directly…

a) I did not @ you
b) I didn’t need a reply, thanks, so you not replying is not really a threat
c) I was responding to your reply to someone else, which is quoted
d) I have read it back numerous times and I cannot see anything I said which is “utterly fucking rude”
e) I am not wrong
f) if you think what I wrote is utterly fucking rude, I don’t know how you get on with the vast majority of threads on MN…

@LegoEmergency

I called the opticians and spoke to the optom just to get a clearer understanding and resurance that my child has the correct prescription (not under and not over) and he told me what you have said almost word for word! I feel confident that she now has the right prescription and will look into getting the myopia control lenses.

Miyosmart lenses are currently only available for children so I’m baffled as to how you got them for yourself also?

Also I suppose I will know for sure when she gets her new glasses and how clearly so can see from a distance.

Great - that’s good. I hope it all works out well from now on. I would definitely get Miyosmart or Stellest glasses.

This is nonsense.

A glasses prescription is the lens strength required to correct your vision, lenses correct your vision by focussing light at the correct point at the back of the eye. An accurate prescription and a full prescription will both be the lens that does this and will be the same.

You will still see with a too strong myopic prescription because you can focus or accommodate to overcome it, but it's too strong. It's not correct and there's no benefit to it.

The bizarre nonsense on this thread.

Something else that is now worrying me when looking at the 2 prescriptions the first prescription was a axis of 20 in the left eye and the new prescription (2 weeks apart) says axis is 119 in the left eye.

Could someone please help me understand this? Should I be concerned? It seems like such a big difference and now I am worrying which one is correct.

I think you need to query the astigmatism figures, it can only be between 10 and 180 so to have two different figures of 20 and 119 means it can't be a measurement error. What is the cylinder value (the astigmatism power)? The higher this is then the more critical that the angle is accurate (although of course it should be properly measured anyway).

@Imlyingandthatsthetruth

Sorry I'm trying to understand but 20 and 119 are in between 10 and 180? Unless I am missing something?

They are on separate prescriptions so now I am worrying if my child has the correct axis on her prescription.

Sorry, I'll try to be clearer! The "axis" value for astigmatism can only be a single number, it has to be between 10 and 180 degrees. You have two prescriptions with two different values, 20 and 119 degrees. What I was trying to say is that you might get two people measuring the value and getting (say) 40 and 45, because it's not always easy to reproduce the same result, but two measurements shouldn't get answers 100 degrees different. In other words, you do need to go back and say "hey, two prescriptions, widely different axis figures, can you sort this out" or similar.

Does that help?

@Imlyingandthatsthetruth

Yes, I understand. That is my concern, the huge difference. The sph on the fist one was -1.75 and the second was -1.25. Cyle was 0.50 on both. The optom said the first prescription with a diffrent optom was incorrect but he did not mention anything about the axis. It is only now that I have had a bit more time to look into it more. Im surprised the optom didn't speak to me about this . He only really addressed the sph!

Some optoms write prescriptions differently which can produce a difference in the axis by 90 degrees, however, if this is the case one of the cylinder values would need to be with a + in front of it. Does the cyl value on one of them have a + value?

@Th1sisnotadrill

No, both cyl have a - in front.

I am actually really annoyed how they can get it so wrong. It is quite worrying that there are optoms out there giving out these incorrect prescriptions! I find it really concerning.

Yes, you have the classic problem where you have two answers that disagree - if you had three and two agreed you'd be happy!

All I can add is that Contact lens prescriptions do differ from glasses prescriptions and , for small astigmatisms, optometrists may not always correct in contactlenses (I have astigmatism correction in both eyes in my specs but only in one eye in my contacts), but please don't let that muddy the waters, go back and query the axis.

Good luck, it will all work out in the end, everything does you know!

I think you need to go in and speak to them, you may need to speak to whoever did the test, you're beyond my knowledge at this point, I think you need the optician to sit with you and go over the test properly. Go on and ask for a chat maybe? Be upfront about what's happened and that you're worried?

Ah on that case then yes, that's 2 wildly different prescriptions. Was your child given drops on the second test perhaps? Often a child will over accommodate making it difficult to get an accurate reading, but drops paralyse the accommodation and give a true result. That said, it's not usually the axis that is the issue here. Typos are possible, seen it many times in my profession so my moneys on the 1st test being incorrect because of a missing 1 off the axis number.

It's odd to use terminology optom, is that an abbreviation?

Never heard of these lenses before.

Would they be offered to all kids or just those with bad progression?

A bit annoying as I've just had both mine checked recently.

@Imlyingandthatsthetruth

The prescriptions are for regular glasses not contact lenses. She is 10 and I want to slow down her myopia with myopia control but if they can't even get her prescription right!
I am now worried that this could make her myopia worse if it is incorrect.

I'd recommend them to any myopic child, they're relatively new in terms of being available at regular high Street opticians. I've a good number of patients on them and we've had brilliant results!!

Sorry, misunderstood about lenses/glasses
