האופטומטריסט עושה בדיקת ראייה כדי לבדוק רוחק ראייה.

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

So:

• אופטומטריסט = optometrist
• האופטומטריסט = the optometrist

Hebrew attaches the definite article directly to the noun instead of writing it as a separate word.

Hebrew has no indefinite article. There is no separate word for a or an.

So בדיקת ראייה can mean:

• a vision test
• vision testing
• an eye exam

The sentence does not need a separate word for a.

This is a construct phrase in Hebrew, called smikhut.

The basic noun is:

• בדיקה = test, examination

But when it is followed by another noun to mean test of X, it changes form:

• בדיקה → בדיקת

So:

• בדיקת ראייה = vision test
• literally, test of vision

This is a very common Hebrew pattern.

It is a noun + noun combination:

• בדיקת = test of
• ראייה = vision / sight

Together, בדיקת ראייה means vision test or eye exam.

This is more natural in Hebrew than trying to translate English word-for-word.

עושה is the present tense form of לעשות, meaning to do / to make.

Here it means does or performs.

The subject is האופטומטריסט, so the sentence means that the optometrist is doing / does the vision test.

A useful note: in unpointed Hebrew, עושה can also be feminine singular in writing, but here we understand it as matching the masculine noun האופטומטריסט.

Hebrew often uses עשה in places where English prefers a more specific verb.

So עושה בדיקת ראייה is perfectly natural and means something like:

• does a vision test
• performs an eye exam

You could also hear more formal alternatives such as עורך בדיקת ראייה, but עושה is common and easy Hebrew.

Because the verb agrees with the subject, not with the object.

In this sentence:

• האופטומטריסט = the subject
• עושה = the verb
• בדיקת ראייה = the object

So the verb is determined by האופטומטריסט, not by בדיקת.

כדי means in order to or so as to.

It introduces a purpose:

• כדי לבדוק = in order to check

So the second part of the sentence explains why the optometrist is doing the vision test.

לבדוק is the infinitive of the verb בדק, meaning to check / to examine.

The ל־ is part of the infinitive form, similar to English to in to check.

So:

• כדי לבדוק = in order to check

This pattern is extremely common in Hebrew:

• כדי ללמוד = in order to study
• כדי לראות = in order to see
• כדי להבין = in order to understand

רוחק ראייה is the Hebrew term for farsightedness or hyperopia.

It is a fixed expression. Literally, it is built from:

• רוחק = distance / remoteness
• ראייה = vision

So the literal idea is something like distance vision, but the actual medical meaning is farsightedness.

A related term is:

• קוצר ראייה = nearsightedness / myopia

Because it appears in two different expressions:

• בדיקת ראייה = vision test
• רוחק ראייה = farsightedness

Even though the same noun ראייה appears twice, the two full phrases mean different things. This is normal Hebrew and does not sound strange.

Yes. That would be a little more explicit.

• כדי לבדוק רוחק ראייה = to check for farsightedness
• כדי לבדוק אם יש רוחק ראייה = to check whether there is farsightedness / whether the person has farsightedness

The original sentence is understandable and natural enough, but adding אם יש makes the meaning more spelled out.

Yes. This is a very normal order:

• האופטומטריסט = subject
• עושה = verb
• בדיקת ראייה = object
• כדי לבדוק רוחק ראייה = purpose phrase

So the structure is basically:

subject + verb + object + purpose

That is a standard and clear way to build a sentence in Hebrew.

ראייה is pronounced roughly re-iyah.

The spelling with יי helps represent the -iya sound in modern Hebrew spelling without vowel marks.

So although the spelling may look unusual at first, it is a normal modern Hebrew way to write the word for vision / sight.
