Проверка зрения включает проверку поля зрения.

Russian often expresses of-relationships by putting the second noun into the genitive case instead of adding a separate word.

So:

• проверка = check / test
• зрения = of vision / of eyesight

That means Проверка зрения literally works like check of vision, which in natural English becomes vision test or eye test.

The same thing happens again in:

• проверку поля зрения = check of the field of vision

This noun + genitive pattern is extremely common in Russian.

Because it depends on another noun.

The base form is:

• зрение = vision, eyesight

After a noun like проверка or поле, Russian commonly uses the genitive to show what something relates to:

• проверка зрения = vision test
• поле зрения = field of vision

So зрения is the genitive singular of зрение.

A useful way to think about it is:

• что? зрение = vision
• чего? зрения = of vision

Because the two forms play different grammatical roles in the sentence.

• Проверка is the subject of the sentence, so it is in the nominative case.
• проверку is the direct object of включает, so it is in the accusative case.

This is a feminine noun ending in -а, so:

• nominative: проверка
• accusative: проверку

So the structure is:

• Проверка зрения = The vision test / A vision test
• включает = includes
• проверку поля зрения = a check of the visual field

Включает means includes.

It comes from the verb включать. In this sentence it is:

• 3rd person singular
• present tense
• imperfective

So:

• включать = to include
• включает = includes / is including

In a general statement like this, Russian normally uses the imperfective:

• Проверка зрения включает... = A vision test includes...

This describes what such a test generally contains.

Because the sentence is describing a general fact, not a single completed action.

Russian often uses the imperfective for:

• definitions
• general truths
• habitual actions
• descriptions of what something normally involves

Here the idea is:

• A vision test includes a visual field test

It is not about one test finishing the action of including something. It is just stating what is typically part of the test.

The perfective partner is включить, but that would not sound right in this kind of general-definition sentence.

They are related but not the same.

• зрение = vision / eyesight in general
• поле зрения = field of vision / visual field

So:

• Проверка зрения = a general vision test
• проверка поля зрения = a more specific test of your visual field, meaning how wide an area you can see without moving your eyes

In other words, the second phrase names one specific part of the broader vision test.

Yes, that is completely normal.

The sentence contains two different genitive phrases:

• Проверка зрения = vision test
• проверку поля зрения = check of the field of vision

Even though зрения appears twice, it belongs to two different noun groups:

1. проверка зрения
2. поля зрения

This repetition may sound a little heavy in English, but in Russian it is perfectly natural, especially in formal or medical language.

Yes. Поле зрения is a standard expression meaning field of vision or visual field.

It is used in:

• medical contexts
• scientific contexts
• sometimes figurative contexts too

For example, figuratively, something can попасть в поле зрения someone, meaning come into someone’s field of view / attention.

But in your sentence it is literal and medical.

Russian does not have articles.

So a phrase like Проверка зрения can mean:

• a vision test
• the vision test
• vision testing

Which one sounds best depends on context and the English translation style.

In your sentence, English most naturally says:

• A vision test includes a visual field test or
• Vision testing includes visual field testing

Russian leaves that more open, and context usually makes it clear.

Yes, Russian word order is fairly flexible, because case endings already show the grammatical roles.

The neutral order here is:

• Проверка зрения включает проверку поля зрения.

This is the most straightforward way to say it.

You could move things around for emphasis, but the original order sounds the most natural in a neutral explanatory sentence.

For example, putting проверку поля зрения earlier would add emphasis to that element, but it would sound less plain and textbook-like.

A good strategy is to group the sentence into chunks:

• Проверка зрения
• включает
• проверку поля зрения

Now look inside each chunk:

1. Проверка зрения

   • head noun: проверка
   • dependent genitive: зрения

2. проверку поля зрения

   • head noun: проверку
   • dependent phrase: поля зрения
   • inside that phrase, зрения depends on поля

So the structure is layered:

• [check] [of vision]
• includes
• [check] [of [field [of vision]]]

This kind of nesting is very common in Russian formal writing.

The main stress pattern is:

• провЕрка зрЕния включАет провЕрку пОля зрЕния

Word by word:

• провЕрка
• зрЕния
• включАет
• провЕрку
• пОля
• зрЕния

A rough pronunciation guide:

• pra-VYER-ka ZRYE-nee-ya vklyu-CHA-yet pra-VYER-ku PO-lya ZRYE-nee-ya

The exact sounds are best learned by listening, but knowing the stress is very helpful, because unstressed vowels change in Russian.
