can vision always be corrected by eyeglasses?

I went to see optometrist to do my eye exam, but right eye just can't
see clearly it seems with correction lenses (he said he doesn't know
why), my question is can vision always be corrected by eyeglasses? if
not, why?

thanks a lot!

Even though I am not a health professional, I can confidently say that the
answer is a resounding NO!

First of all, there are conditions that have more to do with the
neurological aspects of vision that cannot be corrected that way. Retinal
problems are of that character too. Cataracts and other optical blockages
cannot be corrected.

What glasses can do is to compensate for imperfect optical systems of eyes
with clear optics. In many cases pinhole glasses can be used to distinguish
between what is correctible with lenses and what is not.

Another problem is that lenses will compensate only for simple optical
problems such as focus and cylinder. There also are higher order aberrations
that cannot be corrected because the lenses are too complicated to
manufacture. Even if an aberration could be corrected, turning the eye to
look into another directions makes such correction useless.

that makes sense, i tried to look through a small pinhole and my right
eye sees better than with my eyeglasses, I guess that means I don't
have vision problem other than the eye, should be correctable with
eyeglasses? (ignoring the higher order of aberration which should be in
the higher details)

Any time vision is not corrected with glasses, there must be an
explanation. Him just not knowing is unacceptable and the reason must
be found. You definitely need a 2nd opinion.

The important information left out by (E-Mail Removed) was how well he was
able to see with best correction.

ok my right eye can't read text on computer screen, either naked or
with current eyeglasses (which has very old prescription SPH= -2.50,
CYL= -1.25, AXIS=171), I want to get a new pair of eyeglasses, the new
optometrist gave me new prescription -2.25, -1.50, 170, which is about
the same as the old one, that's why I am concerned, and during the exam
process my right eye can't see well with his lenses... I just like to
know if this is the best optics can do or something I must investigate
more...

thanks

No, for many reasons. Depending on how bad your corrected vision is,
"doesn't know why" is not an acceptable answer.

Somebody here should be able to tell you what is worth following up on
and what isn't. My vision wasn't correctable with glasses and I had
surgeries in both eyes. This required a referral to an eye MD.

not sure if I have cataract but I doubt my eye has any illness since I
don't feel anything uncomfortable, it has been like that for many
years. maybe I should get a "comprehensive eye exam"? thanks

I would think this is exactly the situation for which pinhole glasses would
be useful. If you can see clearer with them than without, that would be an
indication that the prescription is not correct or that there are
uncorrected aberrations that ordinarily cannot be corrected with
opthalomological lenses.

Might want to see a good eye doctor.

A couple of years back my vision got fuzzy. I went to my eye doctor
thinking I needed a new prescription. She diagnosed corneal edema
instead. Salt drops took care of it and my vision cleared without a
prescription change.
