الوهج على العدسة المقاومة للخدش بالتأكيد.

Arabic often allows verbless sentences, especially in the present tense.

So الوهج على العدسة المقاومة للخدش بالتأكيد can work as an elliptical statement like:

• It is definitely the glare on the scratch-resistant lens
• Definitely the glare on the scratch-resistant lens

This is very normal in Arabic. The verb to be is often omitted in the present tense.

A helpful breakdown is:

• الوهج = the glare
• على العدسة المقاومة للخدش = on the scratch-resistant lens
• بالتأكيد = certainly / definitely

So the structure is basically:

• noun
• prepositional phrase
• adverb

You can think of it as a noun phrase with extra description added after it.

الوهج means glare, bright glow, or dazzling brightness.

It usually refers to strong light that shines or reflects in a way that can be visually noticeable or annoying.

It is:

• masculine
• singular
• definite because of الـ

So الوهج = the glare.

العدسة is a feminine noun in Arabic. It means the lens.

Because المقاومة is describing العدسة, it must match it in:

• gender: feminine
• number: singular
• definiteness: definite

So:

• العدسة = feminine singular definite
• المقاومة = feminine singular definite

That is why you see المقاومة rather than a masculine form.

Here it functions as an adjective describing العدسة.

Literally, المقاومة comes from a form related to resisting. In this sentence, it means something like:

• resistant
• resisting
• scratch-resistant when combined with للخدش

So العدسة المقاومة للخدش means:

• the lens that is resistant to scratching
• more naturally, the scratch-resistant lens

It is not acting like a main verb here.

Arabic often expresses this kind of idea with a descriptive phrase rather than a single compact adjective.

So:

• المقاومة = resistant / resisting
• للخدش = to scratching / against scratching

Together:

• المقاومة للخدش = resistant to scratching
• natural English translation: scratch-resistant

This is a very common Arabic pattern.

Because the adjective المقاومة normally takes the preposition لِـ here.

So:

• لِ = to / for / against, depending on context
• الخدش = scratching / scratch damage

When لِ joins الـ, it becomes:

• لِ + الخدش = للخدش

So المقاومة للخدش literally means resistant to scratching or resistant against scratches.

Here الخدش is best understood in a general sense:

• scratching
• scratch damage
• scratches

Arabic often uses a singular noun with الـ to express a general category or concept.

So للخدش does not have to mean just one specific scratch. It can mean resistance to scratching in general.

Because the adjective must match the noun in definiteness.

• العدسة = the lens
• المقاومة = the resistant

In natural English we would not say the resistant lens, but in Arabic the adjective usually also takes الـ when the noun is definite.

So:

• عدسة مقاومة للخدش = a scratch-resistant lens
• العدسة المقاومة للخدش = the scratch-resistant lens

على is a preposition meaning on.

So:

• على العدسة = on the lens

It tells you where the glare is.

The phrase على العدسة المقاومة للخدش modifies الوهج, giving the location of the glare.

بالتأكيد means:

• certainly
• definitely
• for sure

It is an adverbial expression.

Putting it at the end adds emphasis, something like:

• the glare on the scratch-resistant lens, definitely
• it is definitely the glare on the scratch-resistant lens

Arabic allows fairly flexible placement for words like this, depending on emphasis and style.

It can feel a bit elliptical on its own.

In real usage, it could be:

• a short answer
• part of a longer conversation
• a caption-like statement
• a clipped spoken sentence

For example, if someone asks what is causing a visual problem, this answer could naturally mean:

• Definitely the glare on the scratch-resistant lens

So yes, it is understandable, but it may depend on context more than a fully expanded sentence would.

A simple pronunciation guide is:

al-wahaj ʿalā al-ʿadasa al-muqāwima lil-khadsh bi-taʾkīd

A few notes:

• الوهج = al-wahaj
• عدسة has the letter ع, which is a deep throat sound not found in English
• للخدش is pronounced lil-khadsh
• بالتأكيد = bi-taʾkīd

If you are reading without case endings, this pronunciation is fine for normal Modern Standard Arabic reading.

Yes, literally it comes from the idea of resisting, but that literal translation sounds unnatural in English.

So:

• literal sense: the lens that resists scratching
• natural English: the scratch-resistant lens

When learning Arabic, it is often useful to know both:

1. the literal structure
2. the natural English meaning

That helps you understand how Arabic builds descriptive phrases.
