עם עדשות פרוגרסיביות יש לי פחות מאמץ עיניים.

Because עדשות is a feminine plural noun, and the adjective has to match it.

• עדשה = lens
• עדשות = lenses
• פרוגרסיבית = progressive (feminine singular)
• פרוגרסיביות = progressive (feminine plural)

So עדשות פרוגרסיביות means progressive lenses, with full gender/number agreement.

Literally, יש לי means there is to me. Hebrew usually does not use a normal present-tense verb for to have. Instead, it uses יש plus a person marker:

• יש לי = I have
• יש לך = you have
• יש לו = he has
• יש לה = she has

So יש לי פחות מאמץ עיניים is literally something like there is less eye strain to me, but in natural English we say I have less eye strain or I experience less eye strain.

Because in modern Hebrew, possession in the present tense is normally expressed with יש ל־ rather than a standalone verb meaning have.

So instead of something like I have less eye strain, Hebrew says:

יש לי פחות מאמץ עיניים

This pattern is extremely common, not just for possessions but also for conditions and experiences:

• יש לי זמן = I have time
• יש לי כאב ראש = I have a headache
• יש לי בעיה = I have a problem

Hebrew often puts a prepositional phrase first to set the scene or frame the statement. Here, עם עדשות פרוגרסיביות tells you the condition first: with progressive lenses.

That gives the sentence a natural flow like: With progressive lenses, I have less eye strain.

You could move it later in the sentence, but the original version sounds very natural because it highlights the circumstance first.

פחות means less or fewer, and in this kind of comparison it usually stays the same. It does not agree like a regular adjective here.

Examples:

• פחות זמן = less time
• פחות בעיות = fewer problems
• פחות מאמץ = less effort / less strain

So פחות מאמץ עיניים is simply less eye strain.

It is a noun phrase meaning eye strain. Literally, it is something like strain of the eyes.

• מאמץ = effort, strain
• עיניים = eyes

Hebrew often combines nouns this way to make compact expressions. So מאמץ עיניים works like a set phrase meaning eye strain.

Because Hebrew uses eyes in the plural in this expression. Even though English says eye strain, the strain affects the eyes, so Hebrew naturally says מאמץ עיניים.

Also, עיניים is the regular word for eyes, and body-part expressions often work a little differently from English. So this is a normal idiomatic difference, not a special grammar problem.

Because the sentence is speaking generally, not about a specific named pair of lenses or a specific instance of eye strain.

So:

• עם עדשות פרוגרסיביות = with progressive lenses, in general
• פחות מאמץ עיניים = less eye strain, in general

If you meant a specific pair, you could say: עם העדשות הפרוגרסיביות... = with the progressive lenses...

It is basically a borrowed international word adapted to Hebrew pronunciation and grammar. That is very common in modern Hebrew, especially for technical or medical/optical terms.

So פרוגרסיבי / פרוגרסיבית / פרוגרסיביות behaves like a normal Hebrew adjective even though its origin is foreign.

A simple pronunciation guide would be:

im adashot progresiviyot yesh li pachot ma'amatz einayim

A few useful parts:

• עם = im
• עדשות = adashot
• יש לי = yesh li
• פחות = pachot
• מאמץ = ma'amatz
• עיניים = einayim

It can absolutely mean an experience or condition. In this sentence, יש לי פחות מאמץ עיניים does not mean you somehow own eye strain. It means you experience less eye strain.

Hebrew uses יש לי very naturally for symptoms, feelings, and conditions, not only for physical possessions. So this wording is completely normal.
