בגלל אסטיגמציה, התמונה מטושטשת.

A natural pronunciation is:

biglal astigmatzya, hatmuna metushteshet.

Approximate stress:

• bigLAL
• astigmatzYA
• hatmuNA
• metushtE-shet

A more phonetic breakdown:

• בגלל = biglal
• אסטיגמציה = astigmatzya
• התמונה = hatmuna
• מטושטשת = metushteshet

בגלל means because of and is a preposition.

In this sentence, it introduces the cause:

• בגלל אסטיגמציה = because of astigmatism

This is different from saying because before a full clause. For example:

• because of astigmatism → בגלל אסטיגמציה
• because I have astigmatism → often כי יש לי אסטיגמציה or בגלל שיש לי אסטיגמציה

So here, בגלל is followed by a noun, not a full sentence.

In Hebrew, the verb to be is usually omitted in the present tense.

So:

• התמונה מטושטשת literally looks like the picture blurry
• but it means the picture is blurry

This is completely normal Hebrew.

Compare:

• התמונה מטושטשת = The picture is blurry
• התמונה הייתה מטושטשת = The picture was blurry
• התמונה תהיה מטושטשת = The picture will be blurry

So the missing is is not a mistake; it is standard grammar.

The comma marks the opening phrase בגלל אסטיגמציה as a fronted cause phrase.

The sentence is structured like:

• Because of astigmatism, the picture is blurry.

In Hebrew, this comma is natural when the cause comes first.

You could also say:

• התמונה מטושטשת בגלל אסטיגמציה.

That version usually does not need a comma, because the cause comes at the end.

התמונה means the picture/image.

The prefix ה־ is the definite article, equivalent to the in English.

So:

• תמונה = a picture / picture
• התמונה = the picture

In this sentence, we are talking about a specific image, so Hebrew uses the definite form.

Because it agrees with התמונה, which is feminine singular.

In Hebrew, adjectives must agree with the noun in:

• gender
• number
• definiteness in some constructions

Here:

• תמונה is feminine singular
• so the adjective is feminine singular too: מטושטשת

Compare:

• masculine singular: מטושטש
• feminine singular: מטושטשת
• masculine plural: מטושטשים
• feminine plural: מטושטשות

So if the noun changed, the adjective would also change.

You usually learn the gender of nouns along with the word itself.

תמונה is a feminine noun. One clue is that many feminine nouns end in -ה or -ת, and תמונה ends in -ה. That pattern is common, though not every noun follows it perfectly.

Because תמונה is feminine, anything describing it must match:

• תמונה יפה
• תמונה ברורה
• תמונה מטושטשת

In this sentence, מטושטשת functions like an adjective: blurry / blurred.

It comes from the root ט־ש־ט־ש, which has to do with blurring or smudging.

In everyday Hebrew, learners can safely treat מטושטש / מטושטשת as an adjective meaning:

• blurry
• blurred
• fuzzy
• indistinct

So:

• התמונה מטושטשת = The picture is blurry
• הטקסט מטושטש = The text is blurry

Yes. Hebrew allows both of these:

• בגלל אסטיגמציה, התמונה מטושטשת.
• התמונה מטושטשת בגלל אסטיגמציה.

Both are natural.

The difference is mainly emphasis:

• starting with בגלל אסטיגמציה highlights the cause first
• ending with it sounds a bit more neutral

This is similar to English:

• Because of astigmatism, the picture is blurry.
• The picture is blurry because of astigmatism.

It is a loanword, basically the Hebrew form of astigmatism.

Hebrew often uses international medical terms, adapted to Hebrew spelling and pronunciation. So אסטיגמציה is not a traditional Semitic Hebrew root word in the way something like תמונה is.

That is why it may look a little different from native Hebrew vocabulary.

It depends on the meaning.

• בגלל אסטיגמציה = because of astigmatism in a general sense
• בגלל האסטיגמציה = because of the astigmatism, referring to specific known astigmatism

In your sentence, the version without ה־ sounds natural if you mean the condition generally.

So both are possible, but they are slightly different in nuance.

The main thing that changes is the adjective.

Examples:

• feminine singular: התמונה מטושטשת
  The picture is blurry

• masculine singular: המסך מטושטש
  The screen is blurry

• feminine plural: התמונות מטושטשות
  The pictures are blurry

• masculine plural: המסכים מטושטשים
  The screens are blurry

This is a very common Hebrew pattern: adjectives must match the noun.

It depends on context.

תמונה is a broad word and can mean:

• picture
• image
• photograph

So in this sentence, התמונה מטושטשת could mean:

• the picture is blurry
• the image is blurry
• the photo is blurry

If the wider context is vision or optics, image may feel especially natural. If the context is a photo, photo may be best. Hebrew itself leaves that open here.
