قوة العدسة لقصر النظر في وصفة النظارة.

Not really. It is better understood as a noun phrase or label, not a full sentence with a verb.

This kind of wording is very common in Arabic on:

• forms
• medical documents
• charts
• prescriptions
• headings

So it works like an English label such as Lens power for myopia in the glasses prescription rather than a full sentence like The lens power for myopia is listed in the glasses prescription.

A fully vocalized version would be:

قُوَّةُ العَدَسَةِ لِقِصَرِ النَّظَرِ فِي وَصْفَةِ النَّظَّارَةِ

A careful transliteration is:

quwwatu al-ʿadasati li-qiṣari an-naẓari fī waṣfati an-naẓẓārati

A few notes:

• قوة = quwwa(tu), with a doubled w
• العدسة begins with ʿayn, so al- is pronounced clearly
• النظر and النظارة begin with n, a sun letter, so al- assimilates: an-naẓar, an-naẓẓāra

In normal unvoweled writing, those short vowels are simply not shown.

It is built out of several connected noun phrases and prepositional phrases:

• قوة العدسة = the power of the lens / lens power
• لقصر النظر = for myopia / for nearsightedness
• في وصفة النظارة = in the glasses prescription

So the structure is roughly:

[noun phrase] + [prepositional phrase] + [prepositional phrase]

This is very common in formal Arabic, especially in technical or medical wording.

Because قوة العدسة is an iḍāfa construction, often called a genitive construction.

In an iḍāfa:

• the first noun usually does not take الـ
• the second noun determines whether the whole phrase is definite

So:

• قوة عدسة = lens power or power of a lens
• قوة العدسة = the lens power or power of the lens

The first word قوة stays without الـ, even when the whole phrase is definite.

Yes. وصفة النظارة is also an iḍāfa.

It literally looks like:

• وصفة = prescription
• النظارة = the glasses / the eyeglasses

So وصفة النظارة means something like:

• the eyeglasses prescription
• literally the prescription of the glasses

English often uses one noun before another, while Arabic often uses this X of Y structure.

The لـ here is the preposition لِـ, which often means:

• for
• to
• related to

So:

• قصر النظر = myopia / nearsightedness
• لقصر النظر = for myopia / relating to myopia

In writing, Arabic frequently attaches short prepositions directly to the following word, so لِ + قصر becomes لقصر.

Literally, قصر النظر means shortness of sight/vision.

Word by word:

• قصر = shortness, brevity, limitation
• النظر = sight, vision, looking

As a medical expression, it means myopia or nearsightedness.

This is actually similar to British English short-sightedness.

Yes, وصفة can mean both recipe and prescription.

The core idea is something like a written set of instructions.

So depending on context:

• in cooking, وصفة = recipe
• in medicine, وصفة = prescription

Here, because the phrase is about lenses and vision, وصفة النظارة clearly means glasses prescription, not a cooking recipe.

Arabic often uses a singular form where English uses a plural-looking word.

So نظارة can mean:

• a pair of glasses
• eyeglasses

Even though English says glasses, Arabic can use the singular noun naturally.

You may also see نظارات, but نظارة is very common when referring to eyewear as one item.

In fully inflected MSA, the phrase would be:

قُوَّةُ العَدَسَةِ لِقِصَرِ النَّظَرِ فِي وَصْفَةِ النَّظَّارَةِ

Here is why:

• قوةُ is nominative because it is the head noun of the phrase
• العدسةِ is genitive because it is the second term of an iḍāfa
• قصرِ is genitive because it comes after لِ
• النظرِ is genitive because it is the second term of an iḍāfa
• وصفةِ is genitive because it comes after في
• النظارةِ is genitive because it is the second term of an iḍāfa

In ordinary writing, these endings are usually omitted, but understanding them helps a lot with grammar.

You can understand it word-for-word, but a fully literal translation may sound awkward in English.

A very literal breakdown is:

• قوة = power
• العدسة = the lens
• لقصر النظر = for nearsightedness
• في وصفة النظارة = in the glasses prescription

But natural English would usually reorganize it. Depending on context, you might say:

• Lens power for myopia in the glasses prescription
• The lens power for nearsightedness in the eyeglass prescription
• Myopia lens power in the glasses prescription

So yes, you can translate it piece by piece, but English often prefers a different order.

Normally, it describes the broader idea of lens power for myopia and tells you where this information appears: in the glasses prescription.

So the most natural reading is:

[Lens power for myopia] [in the glasses prescription]

In other words, في وصفة النظارة is giving the context or location of the information, not redefining قصر النظر by itself.
