Not happy with my glasses/prescription - chance of double vision?

[l***@gmail.com]

So once again I got a set of glasses that I am not happy with. I hope that someone in here can give me a second opinion on my issues.

When I am sitting in the opticians chair looking through his "old style machine", I often got problems in seeing difference when the optician asks "what is best? 1 or 2". Results are that glass prescriptions are different every time I get a new result from the optician

They are also different from what the automatic machine (the one where you look at a picture that looks like "Southfork" from Dallas) reads out. Are these machines not trusted? Why does the optician also measure the vision "old style"?

IF it helps, I can try to post the different prescriptions.

I have very different strength on my eyes. One is -2.5 the other is -5,75 (although sometimes measured -5.5 and some times -5.25 and then again sometimes -5.0)

Because of the different strength of my eyes, I think that my brain compensates by only using one eye. One doctor told me, that I am not "allowed" to have full strength on my bad eye as I might develop double vision. Is this true?

I also got astigmatism. Even this is measured quite different from each visit to the optician.

Regards, Lars.

I'm sorry to hear you're having trouble wit
your glasses. It can be really frustrating when you don't get th
clarity you need.

When it comes to the "old style machine" (phoropter) versu
the automatic machine (autorefractor), both have their roles. Th
phoropter allows the optician to fine-tune your prescription based o
your subjective responses, which can be more accurate for you
specific needs. The autorefractor gives a quick, objectiv
measurement, but it might not always match perfectly with what yo
feel is best. That's why opticians use both methods to cross-check an
ensure the best possible prescription

Variations in prescriptions can happen due to several factors. You
vision can fluctuate throughout the day due to fatigue, lightin
conditions, or even your overall health. It's also common for peopl
with significant differences in eye strength (anisometropia) t
experience these variations. Your brain might indeed compensate b
favoring one eye, which can complicate getting the perfec
prescription.

Regarding the advice about not having full strength on your bad eye
it is true that overcorrecting can sometimes lead to issues lik
double vision. This is because your brain has adapted to th
imbalance, and suddenly changing that can cause problems.

Astigmatism measurements can vary because it's influenced by the shap
of your cornea, which can change slightly over time or due t
different measurement techniques.

Posting your different prescriptions might help others give mor
specific advice, but it sounds like you're dealing with a comple
situation that might benefit from a second opinion from anothe
optometrist. Hang in there, and I hope you find a solution that work
for you
