Medical Forum / General / Vision / August 2005Adapting to new prescription
I'm having a heck of a time adapting to my new prescription. I have a fairly minor prescription to begin with, something like 0.25 power and 1.25 cylinder in both eyes. For this go around, I think they went from 1.0 to 1.25 cylinder in one eye. I've had the glasses for about a week and they are still driving me crazy. Everything is sharp, for the most part, and I can definitely tell things are sharper than they used to be in the ey that changed, but I have this vague disoriented feeling all the time, and it's really bad when I go outside and look far away - I basically feel kind of cross eyed looking at a distance. I get the same thing to a lesser extent just watching TV. I'm not sure if it's related, but especially when watching TV I have a strong urge to turn my head to an angle with the TV and watch kind of out of the corner of my eye. Any words of wisdom? Should I just keep trying to adapt for another week or two, or is this unusual? If you've worn them more or less full time for a few days and are still bothered, there is something wrong with the Rx or the glasses or both. The head turn bit makes me think you've got a serious distortion in the center of one or both of the lenses. Have them checked by a disinterested party against the written Rx, for starters. w.stacy, o.d. > I'm having a heck of a time adapting to my new prescription.

The problem is so subtle that I think maybe I'm just more sensitive than most people and should give it more time. I've already been back once since I was not even close to adapting last time. It wasn't the glasses themselves, it was the prescription. In addition to increased astigmatism, they had more power in the other eye and that was really driving me nuts. This time I'm close to adapting, and as I said, things are fairly crisp. I don't want to be the problem patient... One other thing I've noticed while obsessing over this problem is that things are a little sharper looking out of the left side of the lens, like if I point my head to the right while looking at the text I'm typing. This is true on both eyes. Shouldn't the prescription stay fairly constant over my field of view, except for maybe the very very edge? >If you've worn them more or less full time for a few days and are still >bothered, there is something wrong with the Rx or the glasses or both.

This is a matter of your choice, but it seems that you have SLIGHT hyperopia. You might try a mild "plus" over-the-counter glass for reading -- and see if this is easier for you. Best, Otis (Engineer) charles, please ignor the posting from otisbrown. his reply is moronic, and he is untrained as an eyecare professional. he insist on posting in this forum and he misleads people constantly. if you have astigmatism of about 1.00 to 1.25 diopters then a spherical lens would be totally inappropriate. also, OTC reading glasses will be totally ineffective for the problems you are describing. getting adjusted to a change in your astigmatism correction would be my best guess about what you are going through. as mentioned by William Stacy, why not get the prescription in the glasses verified against the prescription that was written out for you when you had your examination. if the specs have been made correctly, i would see my eyedoc again and let him know what your problems are. this is not an uncommon situation for your eyedoc. Dear Charles, A "spherical equivalent" will have equal power in all segments. If this lens gives you 20/20, then perhaps the astigmatism "cut" is not that "necessary". Give it a try. Best, Otis (Engineer) > If this lens gives you 20/20, then perhaps the > astigmatism "cut" is not that "necessary". > Give it a try. Of course, you'll reimburse him for new lenses when it doesn't work. -MT otis every time you open your mouth you stick your foot in farther and demonstrate your ignorance more if a patient has one diopter or more of astigmatism, spherical lenses are inappropriate. why do you think reading glasses will help him when he has a distance complaint of distortion? where did you get the idea he is hyperopic\/ he is an astigmat you should go to some other forum. sick, pathetic, old fool > Dear Charles, Dear Charles, Please disregard Otis's postings. He is not in the medical profession nor is he in the position to give medical advice. Thank you! Allen >I'm having a heck of a time adapting to my new prescription. I had the same problem with my last set of spectacles (updated Rx, new frames, new lenses). It was so bad that I actually reverted to my old spectacles. The optician kept telling me nothing was wrong with the new spectacles, so I took them with when I went in for a contact lens fitting earlier in the summer. My ophthalmologist's optician (they only do Medicaid fabrication, hence he's not *my* optician) checked the Rx of each lens (correct, sort of) and marked optical center. On the left lens the OC was 13mm high, on the right lens it was 7mm low. Additionally, the left lens (the one with the high astigmatism correction) was mounted incorrectly in the frame; it had been rotated 90 degrees. And finally, the new lenses were not the same material as the old ones, but were a cheaper (lower index?) material. Because of the difference in materials the geometry of the lens backs is substantially different between the old and new lenses. This produced a lot of visual disorientation on top of the other problems, especially if I turned my head too quickly. The upshot: My optician (the one who fabricated the spectacles) gave me a full refund and my OD's office put new lenses in my old frames. Featherweight titanium is so much more comfortable than plastic, even if the new frames were a bit nicer-looking on my face. +++++++++++++ Reply to the list as I do not publish an email address to USENET. This practice has cut my spam by more than 95%. Of course, I did have to abandon a perfectly good email account... Dear Charles, Subject: Some "effect" of an astigmatic lens. You might call your OD and state that you would like your astigmatic "correction" converted to "spherical equivalent", and ask that he provide that prescription to you. Some people have these "reactions" to an astigmatic "cut" in the lens. If he refuses to do this -- please post his response and reasons. Best, Otis > Dear Charles, > [quoted text clipped - 5 lines] > and ask that he provide that prescription > to you. Giving Moronic advice again Otis? Dear Charles, Please ignore Otis (who conveniently forgot to state here that he is an engineer) > Some people have these "reactions" to > an astigmatic "cut" in the lens. True, but there are several other solutions to his problem. What suprizes me is that you are willing to offer advice that will over prescribe his myopia. Hope Charles has been lurking around here long enough to know what to do with your advice. Otis, Charles has already received good advice from professionals, of course, you think you know better. > If he refuses to do this -- please > post his response and reasons. I would refuse. Anyone here willing to follow Otis's advice and prescribe a spherical equavalent for charles at this point? Roland J. Izaac > Best, > > Otis |
