Poza wadą wzroku wszystko jest dobrze.

Because poza in this meaning normally takes the instrumental case.

• wada = defect, flaw, impairment
• instrumental singular: wadą

So:

• poza wadą wzroku = apart from the vision defect / aside from the eyesight problem

This is a very common pattern:

• poza mną = apart from me
• poza szkołą = outside school / apart from school
• poza problemem = apart from the problem

Here wada wzroku is a noun phrase meaning a defect of eyesight / a visual impairment.
The second noun, wzrok, appears in the genitive case: wzroku.

This is a common Polish structure:

• wada słuchu = hearing defect
• ból głowy = headache
• kolor włosów = color of hair / hair color

So:

• wada wzroku literally = defect of sight

Here poza means apart from, except for, or aside from.

So Poza wadą wzroku wszystko jest dobrze means something like:

• Apart from the eyesight problem, everything is fine.
• Other than the visual impairment, everything is okay.

Be aware that poza can also mean outside in other contexts:

• poza domem = outside the house
• poza miastem = outside the city

So its meaning depends on context.

They are similar, but not always identical.

In this sentence, both can work:

• Poza wadą wzroku wszystko jest dobrze.
• Oprócz wady wzroku wszystko jest dobrze.

The difference is mainly grammatical:

• poza usually takes the instrumental
• oprócz takes the genitive

So:

• poza wadą
• oprócz wady

In everyday speech, both can mean apart from / except for, but poza can also more easily suggest leaving something aside or setting it apart from the rest.

This is a very common learner question.

• dobrze = well, fine, okay (adverb)
• dobre = good (adjective, neuter singular)

In Polish, when speaking generally about how things are going, people often say:

• jest dobrze = it is fine / things are good

So wszystko jest dobrze means everything is fine.

You may also hear:

• wszystko jest w porządku = everything is okay
• wszystko jest okej = everything is okay

Grammatically, wszystko jest dobre is possible in some contexts, but it usually means everything is good in the sense of quality, which is not the most natural meaning here.

It is understandable and acceptable, but many native speakers would more naturally say:

• Poza wadą wzroku wszystko jest w porządku.
• Poza wadą wzroku wszystko jest okej.
• Poza wadą wzroku wszystko jest dobrze.

The version with dobrze is not wrong, but w porządku often sounds a bit more idiomatic when talking about a general situation, condition, or state.

Wada wzroku is a normal and common expression for a vision problem or refractive error, such as:

• nearsightedness
• farsightedness
• astigmatism

It is not overly technical, but it is more specific than just saying problem ze wzrokiem.

Compare:

• wada wzroku = eyesight defect / visual impairment
• problem ze wzrokiem = problem with eyesight
• słaby wzrok = poor eyesight

Yes. Polish word order is flexible, though some versions sound more natural in certain contexts.

Possible versions:

• Poza wadą wzroku wszystko jest dobrze.
• Wszystko jest dobrze poza wadą wzroku.
• Poza wadą wzroku jest wszystko dobrze. — possible, but less natural

The original sentence is natural because it starts with the exception and then gives the main statement:

• Apart from the eyesight problem, everything is fine.

That structure is very common.

A rough pronunciation guide:

• Poza ≈ PO-za
• wadą ≈ VA-dong
• wzroku ≈ VZRO-koo
• wszystko ≈ FSHIST-ko
• jest ≈ yest
• dobrze ≈ DOB-zhe

A more connected approximation:

PO-za VA-dong VZRO-koo FSHIST-ko yest DOB-zhe

A few useful pronunciation notes:

• w sounds like English v
• rz in dobrze sounds like zh
• ą at the end of wadą is nasal; before a pause it often sounds roughly like -om / -ong
• wsz in wszystko is a consonant cluster that can be tricky at first

Polish has no articles. There is no direct equivalent of a or the.

So:

• wada wzroku can mean an eyesight defect, the eyesight defect, or just eyesight problems, depending on context.

You understand the exact meaning from the situation, not from an article.

Yes, very naturally. It sounds like something someone might say after describing a medical checkup or someone’s condition:

• Apart from the eyesight issue, everything is fine.

It could refer to:

• a doctor’s assessment
• a school or workplace medical exam
• a general summary of someone’s condition

So the sentence is broad enough to fit many real-life contexts.

More formal:

• Poza wadą wzroku wszystko jest w porządku.
• Z wyjątkiem wady wzroku wszystko jest w porządku.

More casual:

• Poza wzrokiem wszystko okej.
• Poza problemem ze wzrokiem wszystko jest okej.

Notes:

• z wyjątkiem = with the exception of / except for, more formal
• okej = okay, casual and very common
• poza wzrokiem is less precise than poza wadą wzroku, but may sound more conversational depending on context
