قطرة العين وبخاخ الانف جديدين.

Literally, قطرة العين means the eye drop or more literally the drop of the eye.

A few useful points:

• قطرة = a drop
• العين = the eye
• Together, قطرة العين is a normal Arabic way to say eye drops / eye-drop medicine

Even though English often says eye drops in the plural, Arabic can use the singular noun for the medicine item or bottle.

Word for word:

• بخاخ = spray / sprayer
• الانف = the nose

So بخاخ الانف means nasal spray.

Like قطرة العين, this is a noun + noun structure, where the second noun explains what kind of thing it is.

Because in Arabic, the present-tense verb to be is usually not said.

So:

• قطرة العين وبخاخ الانف جديدين = The eye drops and the nasal spray are new

There is no separate word for are here. This is completely normal in Arabic.

Because جديدين is describing both items together.

The sentence has two things:

• قطرة العين
• بخاخ الانف

Since there are exactly two things, Arabic uses the dual form of the adjective.
So جديدين means new for two items.

In Modern Standard Arabic, the nominative dual would usually be جديدان.

But in Egyptian Arabic, the dual commonly appears as -ين, so جديدين is the normal everyday form.

So:

• جديدان = more formal / MSA-style
• جديدين = normal Egyptian usage

That is one clue that this sentence is Egyptian or at least colloquial-style writing.

Because the sentence is talking about two different things together:

• قطرة العين is grammatically feminine
• بخاخ الانف is grammatically masculine

When Arabic has a mixed-gender pair or group, the masculine form is normally used.

So جديدين is the masculine dual form.
If both items were feminine, you would expect جديدتين instead.

Because Arabic usually makes the subject definite and the predicate adjective indefinite.

Here:

• قطرة العين = definite
• بخاخ الانف = definite
• جديدين = predicate adjective, so it stays indefinite

This is very normal Arabic grammar.

Also, قطرة العين is definite because of the idafa structure:

• قطرة
  • العين
• Since العين is definite, the whole phrase becomes definite

The same applies to بخاخ الانف.

Yes, in more careful spelling, especially in Standard Arabic, you would normally write الأنف with a hamza.

But in everyday Arabic typing, many people leave hamzas out, especially in informal writing.

So:

• الأنف = more careful spelling
• الانف = very common informal spelling

Both are understood as the nose.

A natural Egyptian-style pronunciation would be approximately:

'aṭret el-ʕēn wi baxxāx el-ʔanf gedīdēn

A few pronunciation notes:

• ج in Egyptian is usually a hard g, so جديدين sounds like gedīdēn
• خ in بخاخ is the throaty sound heard in German Bach or Scottish loch
• و here is pronounced like wi or we before the next word

It is understandable in both, but it looks more Egyptian / colloquial-friendly than fully formal MSA.

Why?

• جديدين fits Egyptian usage better than formal جديدان
• الانف without hamza is common in informal writing
• The whole sentence feels like practical everyday language

A more formal MSA version would usually be:

قطرة العين وبخاخ الأنف جديدان

So the sentence you have is best thought of as Egyptian-style everyday Arabic, even though the vocabulary is widely understood.
