خلال فحص النظر يضبط إطار النظارة وذراع النظارة.

خلال means during or throughout.

In this sentence, خلال فحص النظر means during the eye exam / during the vision test.

Grammatically, خلال functions like a preposition here, introducing a time expression:

• خلال فحص النظر = during the eye exam

So the sentence begins with a time phrase, and then the main action comes after it.

This is an iḍāfa construction, often called the construct phrase.

فحص النظر literally means:

• inspection/exam of vision
• more naturally: eye exam or vision test

In Arabic, possession or of relationships are often shown by putting two nouns together:

• فحص = exam
• النظر = sight / vision

So:

• فحص النظر = exam of vision

In an iḍāfa:

1. the first noun usually does not take ال
2. the second noun can be definite with ال
3. the whole phrase becomes definite if the second noun is definite

So فحص النظر is correct, while الفحص النظر would be wrong in standard Arabic.

Yes, the root meaning is related to looking or seeing, but النظر can also mean sight or vision, especially in medical or formal contexts.

So in فحص النظر, النظر means:

• eyesight
• vision

This is a common expression for an eye test or vision exam.

In Arabic, the verb can appear without an explicit subject because the subject may be:

1. understood from context, or
2. included in the verb form itself

يضبط means he adjusts / he sets / he aligns.

So the sentence implies a subject such as:

• the optician
• the eye doctor
• the technician

Arabic often leaves this kind of subject unstated when it is obvious from context.

So the sentence is essentially:

• During the eye exam, [the specialist] adjusts the glasses frame and the glasses arm.

Here يضبط means something like:

• adjusts
• sets
• aligns
• fits properly

The basic idea is making something correct, accurate, or properly positioned.

In this context, adjusts is the most natural translation:

• يضبط إطار النظارة وذراع النظارة
• he adjusts the glasses frame and the arm of the glasses

The root is ض ب ط, which often carries the sense of control, precision, regulation, or correct adjustment.

يضبط is in the imperfect form.

In Arabic, the imperfect can express:

• present
• habitual action
• future (depending on context)

Here it is best understood as a present/habitual action:

• During an eye exam, the frame and arm of the glasses are adjusted
• or more literally: he adjusts...

So it describes what typically happens during such an exam.

Arabic allows flexible word order.

The sentence starts with خلال فحص النظر because it sets the scene first:

• During the eye exam...

This is very natural in Arabic. It puts the time context before the action.

So the structure is:

• time phrase
  • verb
    • object

That is completely normal in Modern Standard Arabic.

Yes, إطار النظارة is also an iḍāfa.

It means:

• the frame of the glasses
• more naturally: the glasses frame

Breakdown:

• إطار = frame
• النظارة = the glasses / the eyeglasses

So:

• إطار النظارة = frame of the glasses

Again, the first noun in iḍāfa usually does not take ال, and the second noun determines definiteness.

Because النظارة is definite, the whole phrase is definite:

• إطار النظارة = the glasses frame

Yes. ذراع literally means arm, but it is also used for the arm/side/temple piece of eyeglasses.

So in this sentence:

• ذراع النظارة = the arm of the glasses
• more naturally in English: the glasses arm / the temple piece

This is a common way Arabic extends body-part words to objects that have similar shapes or functions.

This is a very common learner question.

In Arabic, نظارة is often a singular noun meaning a pair of glasses / eyeglasses.

So even though English uses a plural-looking form (glasses), Arabic often uses a singular noun:

• نظارة = glasses / eyeglasses
• النظارة = the glasses

Arabic can also use نظارات, but نظارة as a single item of eyewear is very common.

So:

• إطار النظارة = the frame of the glasses
• ذراع النظارة = the arm of the glasses

This is normal Arabic usage, even if it feels unusual to an English speaker.

Yes, glasses normally have two arms, so this may feel odd from an English perspective.

There are a few reasons Arabic might use the singular here:

1. Generic reference
   The sentence may simply be naming the parts of the glasses in a general way:

   • the frame
   • the arm

2. One part at a time
   In practical or instructional language, Arabic may mention a part in the singular even when the real object has two symmetrical parts.

3. Stylistic simplicity
   The sentence may be simplifying the wording rather than explicitly saying both arms.

If the writer wanted to be very specific about both arms, Arabic could use a dual form such as ذراعا النظارة. But the singular here is still understandable and natural enough in context.

Arabic often repeats the full noun phrase for clarity, especially in formal, educational, or technical language.

So:

• إطار النظارة وذراع النظارة

is very clear and explicit.

A shorter version such as:

• إطارها وذراعها

could also be possible if the context already makes it clear that ها refers to the glasses. But in instructional or textbook-style Arabic, repeating the noun is common because it avoids ambiguity.

Yes.

The verb يضبط takes both as coordinated direct objects:

• إطار النظارة
• وذراع النظارة

The و simply joins them:

• the frame of the glasses and the arm of the glasses

So the structure is:

• يضبط = he adjusts
• إطار النظارة وذراع النظارة = the glasses frame and the glasses arm

Both nouns are things being adjusted.

In fully vocalized form, it would be:

خلالَ فحصِ النظرِ يضبطُ إطارَ النظارةِ وذراعَ النظارةِ.

Here is why:

• خلالَ: after usage as a preposition-like ظرف, it is typically in the accusative
• فحصِ: genitive because it comes after خلال
• النظرِ: genitive because it is the second term of the iḍāfa
• يضبطُ: indicative imperfect
• إطارَ: accusative as a direct object
• النظارةِ: genitive in iḍāfa
• ذراعَ: accusative as another direct object
• النظارةِ: genitive in iḍāfa

In everyday unvocalized Arabic, these endings are usually not written, but they are part of the grammar.

A careful reading would be approximately:

khilāla faḥṣi n-naẓari yuḍbiṭu iṭāra n-naẓārati wa-dhirāʿa n-naẓārati

A few pronunciation notes:

• خ = like a throaty kh
• ح in فحص is a strong breathy h
• ض in يضبط is an emphatic consonant
• ظ in النظارة is also emphatic
• ذ in ذراع sounds like th in this

Also note that in connected reading, ال before ن in النظر and النظارة assimilates, so you hear something like:

• an-naẓar
• an-naẓāra

rather than a clearly pronounced l.

Yes. A very literal translation helps you see the structure, but a more natural English version might be:

• During the eye exam, the glasses frame and temple are adjusted.
• During the vision test, the optician adjusts the frame and arm of the glasses.
• During the eye exam, the frame and side arm of the glasses are adjusted.

Arabic often allows an implied subject, while English sometimes prefers to name it or use a passive construction. So several English versions can be correct depending on style.
