ns666ns@yahoo.com - 08 Sep 2006 05:04 GMT 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.

ns666ns@yahoo.com - 08 Sep 2006 16:37 GMT 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)

It proves your doctor should repeat the refraction before deciding there's anything wrong with your eyes.

ns666ns@yahoo.com - 08 Sep 2006 20:01 GMT 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

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.

John H. - 10 Sep 2006 01:20 GMT All well and good William but I am a person who for 5 years has struggled with visual problems and 3 specialists, including the best in my state, have found no solution. I do have a complex ocular pathology but it is extremely frustrating to have lost 5 years because of an iatrogenically induced pathology. One specialist I saw was an oxygen bandit, total waste of planetary resources, but the others have been brilliant - especially at the teaching hospital. Sadly their brilliance has provided no solution but the prevailing view is that my problem is neurological; particularly as my visual acuity fluctuates wildly through the day. While I only have finger vision in my right eye, I have 6\5- in my left eye. The strong vision in my left eye is not that surprising, early childhood monocular deprivation can result in hyperacuity in the remaining eye, most probably through a rewiring of the V1(read a fascinating study on this sometime ago). My pathologies arising from botched surgery are:
third nerve palsy ptosis (left eye) exotropia (right eye) optic nerve damage (right eye) probably diffuse frontal lobe damage as a result of post surgical bleed.
So I would suggest that the individual get a second opinion, no luck there, off to a neurologist but I would also suggest that an answer is not always forthcoming. Give the bods a break, this is very difficult stuff ... .

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.

TimR - 09 Sep 2006 11:39 GMT 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.
otisbrown@pa.net - 09 Sep 2006 15:10 GMT Dear Tim,
I monitor my vision -- as much as possible -- because of my concern about developing a detached retina.
So I saw the same thing, sligh blur that could not be cleared with a minus lens.
The use of a "pin-hole" showed a clearer image. The "image" was "double", and it was the same thiing, "Edema".
The first check is with the minus lens -- to see if the image can be cleared witha minus.
If that does not work, then use a pin-hole. (Verification by the OD).
Then the ophthamologist did checks for retinal tears, "floaters", (previous incipient detachment and laser surgery), and then the assessment. It was an excellent job by these professionals.
Best,
Otis

BVA less than 20/20 always demands a reason.

Reason is spectacle minification, some irregular astigmatism and lots of high order aberrations. Get a topography to prove this like I did.
ns666ns@yahoo.com - 10 Sep 2006 05:12 GMT I try to find a good optometrist, but strangely I can't find any info of my last optometrist on the web, don't they have to have license and get some degree/education? thanks

Find your state's board of optometry and ask for the public info on him/her. No problem, and yes, we do have to have a license and a degree!

At least in the US. In some other countries, you can practice medicine with a BA. I don't know about the license part.
