Medical Forum / General / Vision / March 2006What the hell is wrong with my eyes?
It was just before christmas last year when they changed, i'm longsighted, my perscription then was L 3.25 R 3.50, these where perfectly fine just before christmas(no problems at all), I went to the opticions and he did a dialation and said my eyes where L5.25 R5.50, I am wearing these now and still have problems with focus, when I look out my glasses people and thing's are blurred but when I relax my eyes when looking through them it goes clear?, same thing if im looking at the pavement then look ahead and everythings blurry then takes a while to get a bit clearer. So stronger glasses dont solve anything, thye could make them the srongest pair ever yet my eyes never feel relaxed anymore, why?. I've been doing eye exercies since christmas and still no differnt, someone mentioned on here it may be Accommodative Insufficiency/dysfunction?, but it's still there 4 months later, what do I need to remedy this? :(.

Ellis: First, please remember that I'm a patient, not a doctor. I've had a lot of experience with issues pretty similar to yours, but still.... One thing that I'm guessing your up against is how correct your prescription is *for you*. There's a saying in prescribing (Melvin Rubin, "The Fine Art of Prescribing Glasses") that you give the patient what they like. Were your 3.25/3.50 glasses too *weak*? Maybe. Are your 5.25/5.50 glasses too *strong*? Maybe. Conventional wisdom in optometry, as I understand it, says that you don't often give somebody their *full cycloplegic power*. In other words, if the drops they gave you *fully* knocked out your accommodative mechanism, and the result was that your true refractive error was 5.25/5.50 ... many/most eye docs would prescribe something short of that. If your accommodative mechanism can't relax fully without the use of these drops ("tonic accommodation") then the 5.25/5.50 leaves you over-corrected. Now ... that said ... do you have vergence disorders?? Do you have esotropia or exotropia?? Do you have convergence excess or convergence insufficiency?? Any of these can play a role in what you're experiencing. How old are you? Are you in bifocals or a single-vision prescription? This may not lend itself to a ready "fix," but may be something that can be properly managed, leaving you with few or no symptoms. My one caveat to you is this: if you were wearing the 3.25/3.50 glasses for many years, and doing a significant amount of near work (reading, computers) during that time, then it wouldn't surprise me one bit if you've developed ciliary spasm and accommodative dysfunction from trying so hard to focus at near. You really need to be thoroughly evaluated in light of all of these things. I wish you luck. Believe me when I say: I know this is difficult.... Hi Neil, The part where you mentioned: ==================================================== My one caveat to you is this: if you were wearing the 3.25/3.50 glasses for many years, and doing a significant amount of near work (reading, computers) during that time, then it wouldn't surprise me one bit if you've developed ciliary spasm and accommodative dysfunction from trying so hard to focus at near. You really need to be thoroughly evaluated in light of all of these things. ===================================================== You are correct, this period was when I was unemployed and used the PC for atleast 7/8 hours a day for 2 years, I now have a job and work outside, only use computer for about 2 hours a day now. Im 21, and wear single vision glasses, I don't know out of those disorders I have, i'll sometimes get convergance issues, flashes of light, increase in floaters in my right eye and my eyes also feel differn't in shape(odd I know). My eye doc said it was "all in my head" and my eyes healthy, it's not "all in my head". Thanks for the help/advice Neil. Ellis. Your problem appears you are overcorrected. As an OD, you don't prescribe the full wetRx, it is an indicator of where you will end up. If you are getting strain with +3.25, you need the script upgraded to + 3.75 or +4.00, not +5.50. Go back to your optom and talk to him about your problems. He should change the script for you. dr grant maybe you need bifocals. I know alot of people who didnt see well from near with glasses till they got bifocals with an add. One lady was amazed how much easier and sharper it was to read with a +1.25 add. > maybe you need bifocals. I know alot of people who didnt see well from > near with glasses till they got bifocals with an add. One lady was > amazed how much easier and sharper it was to read with a +1.25 add. A lot of people who are 21 years old? Not likely.  SignatureDan Abel dabel@sonic.net Petaluma, California, USA >> maybe you need bifocals.

Dan, While I categorically refuse to agree with Ace -- largely because I find him to be rather asinine -- people of all ages can be prescribed bifocals, especially if they have convergence issues (convergence excess comes to mind), accommodative dysfunction, or high hyperopia. Were I born today (first: I'd expect a card, a gift ... something from each of you), they would have put my highly hyperopic eyes in full plus lenses, likely with a reading add ... and my outcome would likely have been different. Born early ... as usual. Dear AceMan, Subject: Stair-case myopia. Is there such a thing as stair-case "hyperopia", where your eyes go "positive" from the wearing of a plus lens all the time? I wonder? Best, Otis there is no such thing at staircase myopia or staircase hyperopia. if you understood the true "dynamic nature" of the eye then you would understand what underlies both types of refractive problems and you would understand the symptoms and treatments for them. but you don't. all you know is some anecdotal stories and some buzzwords and "otisisms" i thought you had been embarrassed off of this forum. that was wishful thinking i guess. >i thought you had been embarrassed off of this forum. that was wishful >thinking i guess. He is, it would seem, grooming his heir apparent, Aceman. A younger, more virile version, to be sure, but one who supplants Otis's senile dementia and aberrant thinking with a history of hallucinogenic drug use and manifest asocial behavior. > Is there such a thing as stair-case "hyperopia", where your > eyes go "positive" from the wearing of a plus lens all the time? Yes, but it also shows up in myopes, who get "better" at the same age. -MT Long time no see Otis! My take is that there really isnt stair case hyperopia as the eyeball can not get shorter, only longer. Most people actually start out mildly hyperopic as tots and undergo emmetropization which should bring them to plano, give or take half a diopter. If plus glasses are used at an early age, this can slow down emmetropization due to lack of accomodation, not giving the chance for axial myopia to cancel out the hyperopia. Had my dad not gotten his plus glasses at age 6, he would still be going thru emmetropization and probably be near plano or very mildly hyperopic. If plus glasses must be pescribed, only give enough plus power for clear distance vision and let accomodation do the rest. Encourage the person to do lots of reading and computer to make his eyeballs enlongate and become less hyperopic. Give even weaker glasses. Once the person gets near plano or sees well enough near and far without glasses, success is reached. Be careful not to go overboard and into myopia. Dear AceMan, Subject: Positive refractive change in primates -- when a plus is applied. Long time no see Otis! Otis> Always pleasant to analyize the behavior of all natural eyes -- in terms or refractive state. My take is that there really isnt stair case hyperopia as the eyeball can not get shorter, only longer. Otis> Not exactly. In a study by a Dr. Smith in Houston, a "plus" was applied to primates, and the refractive state moved "positive", as a dynamic system. Otis> Perhaps we should call this "stair-case" plus changed -- which is what is actually MEASURED, rather than the biased "hyperopia". Otis> From Dr. Guyton's statement, the eye does "change" as the environment is changed. Most people actually start out mildly hyperopic as tots Otis> Actually, at birth, the primate eye's refractive STATE runs between zero to plus 9 diopters. I would not "bother" with the term "mildly hyperopic" for refractive states that are completely NORMAL at birth. and undergo emmetropization which should bring them to plano, give or take half a diopter. Otis> The NORMAL primate eye (in the wild) has refractive states running from zero to +2 diopters. I would be a mistake to call natural refractive states "defects" -- when they are normal. Best, Otis > Otis> The NORMAL primate eye (in the wild) Are we talking about wild humans or some other species again? -Quick catmanx is right. i think you've been given too much plus compared to what you are used to. i'm not sure why your spec Rx was changed but if it needed to be increased at all is should have been in small steps (+0.25 to +0.50). i think you should discuss this with your doctor. do you know what the power of the lenses is in the new glasses he gave you? >catmanx is right. i think you've been given too much plus compared to >what you are used to. i'm not sure why your spec Rx was changed but if >it needed to be increased at all is should have been in small steps >(+0.25 to +0.50). i think you should discuss this with your doctor. >do you know what the power of the lenses is in the new glasses he gave >you? I'm taking *at least* half-credit for this one: [QUOTE] Conventional wisdom in optometry, as I understand it, says that you don't often give somebody their *full cycloplegic power*. In other words, if the drops they gave you *fully* knocked out your accommodative mechanism, and the result was that your true refractive error was 5.25/5.50 ... many/most eye docs would prescribe something short of that. If your accommodative mechanism can't relax fully without the use of these drops ("tonic accommodation") then the 5.25/5.50 leaves you over-corrected. [/QUOTE] Docs: 11,278 Lay people: 3 |
