KC - 04 Oct 2007 14:13 GMT Hi all,
I posted to this group about a month ago and got really great responses, thanks!
I as looking at ordering glasses online. Basically where I would send a frame and prescription in to them and a week or so later I would receive a complete pair of eyeglasses.
I think my prescription is straightforward, I need single vision lenses, prescription about 5.0. I was going to go with Trivex.
Some of the local practitioners that have the material want you to use their frames and I don't really like any of the frames that these specific people have hence my search online.
Does anyone see any issues with ordering this way and then getting a "fitting/adjustment" done at a local optometrist? Apparently the only thing I need other than my prescription is the Pupilary Distance(?).
Would appreciate any advice/recommendations,
Thanks,
Kevin

Zetsu - 04 Oct 2007 15:53 GMT Pupillary Distance (PD) is the distance (usually measured in millimeters) between the centers of the pupils in each eye. This measurement is used when making prescription eyeglasses. Positioning lenses correctly in relation to the pupil centers is especially important for higher powered lenses. (Wiki)

Thanks.
Zetsu - 04 Oct 2007 18:30 GMT >For that matter, you may wish to explain issues like pantoscopic tilt What it means is that, in the case of a minus lens, if the pantoscopic tilt is not fitted correctly then it can be a very big problem for patient because if done incorrectly, unwanted extra minus cylindrical and spherical power will be induced on the 180 axis. In the case of plus lens extra plus spherical and plus cylindrical power in induced on the 180 axis. Basically the end result being that the person will not see correctly through the lenses even though the power of the lens may be perfect. Well yes, that is the explanation.
Zetsu - 04 Oct 2007 18:32 GMT Problems like this is a good demonstration of the uselessness of glasses, and the infinite issues the maker has to consider. The worse the error of refraction, the greater the level of stupidity in wearing the glasses.
Zetsu - 04 Oct 2007 18:34 GMT Pantoscopic tilt can be defined as a rotation around the 180 meridian of vision.
Zetsu - 04 Oct 2007 18:54 GMT Pantoscopic tilt can be defined as a rotation around the 180 meridian of vision.So in the case of this patient Kevin, who is farsighted, a flaw in the pantoscopic tilt would cause unwanted plus spherical and plus cylindrical power to be added, if he was using a + prescription.

KC - 04 Oct 2007 19:36 GMT Neil / Zetsu,
When would someone like a Lenscrafters do that? I got my prescription and handed it into them. This woman walked me around and helped me pick out a frame. She took measurement with these binocular looking things (I guess to figure out PD) and that was it. I came back an hour later and she handed me my new glasses.
I put them on, she heated and twisted the ends (around the ears) so they would be tighter and not move around... and that was it.
When I went back to complain about the spherical and chromatic abberation, she heated and bent the frame basically tightened the curve so it would be closer to my face on the edges and fit more snugly. Anyway, that didn't do anything for the abberations.
That was it. Is the Pantoscopic tilt built into the lens? Did she measure that with the binocular-like tool?
My prescription is +5.00/+5.25, I'm farsighted.
Thanks,
Kevin
Neil Brooks - 04 Oct 2007 21:01 GMT > When would someone like a Lenscrafters do that? Kevin:
The thing that "Zetsu" and I have in common is that neither of us has ANY expertise in this area.
Where we DIFFER is that "Zetsu" will still try to give advice.
Ignore it.
Along with the eye docs and vision researchers, there's a very talented, compassionate, and helpful optician named Robert Martellaro who frequents s.m.v.
You'd do well to get their input on this. I'm highly farsighted, too. Every single element from refraction (the order in which the trial lenses are placed into the trial frame), vertex distance, pantoscopic tilt, etc, etc., etc. is critical for high degrees of refractive error.
More specifics should come from better qualified people. I'm sure they'll chime in.
Take care,
Neil
Zetsu - 04 Oct 2007 21:33 GMT Hello,

Let me quote, to wake you up from your poor ability to remember the short term: "For that matter, you may wish to explain issues like pantoscopic tilt to the original poster. " So you shouldn't be a hypocrite!
>The thing that "Zetsu" and I have in common Yuck! I don't want to have anything in common with you, old man.

That's not being helpful.
Smart people know when to say "I don't know." You're not in that group.
Zetsu - 04 Oct 2007 21:47 GMT I never cut and paste unless I put a reference at the end. Like it will say: 'Wiki', or 'PubMed' at the end. But if I do not add a reference in the end of the post, then it means I am not copying and pasting. Then it is my own words. What makes you think I am copying and pasting, anyway! I never ever plaguerise work as that is very dishonorable.

p.clarkii@gmail.com - 05 Oct 2007 11:47 GMT > Hello, > [quoted text clipped - 9 lines] > > Yuck! I don't want to have anything in common with you, old man. Dear Zetsu jerk,
perhaps neil was being sarcastic when he suggested that you write more BS about pantoscopic tilt, etc. The point is, you are not addressing the real and important questions that the original poster has. instead you are just posting for the sake of posting because you apparently like to see your messages appear on the internet. the poster is a real person with real concerns who is looking for real help from someone who really knows what they are talking about. that is NOT you. in fact, you change your name and alleged identity so much that we have no idea who your really are. are you a 15 year old kid living in england or are you the italian idiot Rishi? who knows and who cares. the point is that you offer nothing of value to anyone who posts here but for some reason you can't resist posting again and again and again.
yuck, go away you pathetic little egotistical idiot. who wants to have anything in common with you anyway.
Zetsu - 05 Oct 2007 15:06 GMT Hi pclar,
First of all I am not a jerk and the only real jerk around here is you, you are the biggest one ever! Anyway Neil wasn't being sarcastic he actually did ask me to 'explain to the original poster' about pantoscopic tilt, and so I did. Now I don't see what problem you have with that, I am just doing my best to help Kevin and you just have to jump on me like I am a big criminal. Yes, I like seeing my messages on the internet but so what. Why wouldn't I? But no that is not the real reason that I am posting.
I am posting because I want to help out the poster here, and I did a lot of research on the internet and it took me a long time to find out about the pantoscopic tilt and now you are telling me off even after all my hard work and I only did it because I was trying my best to help the poster Kevin and I get loads of flames. Plus, I never even changed my name all I did was change my alias what's wrong with that, I don't see what's the problem with changing an alias. It's not like the world is going to end just because I changed it now is it. Now you should stop being so worked up about that. Yes I am 15 years old living in England, no I'm not Rishi.
I am offering things of value to the people who post here, I am telling them how to cure their sight and anyone with a bit of intelligence would at least demonstrate these truths to themselves, that are found when a person begin the cure of imperfect sight with the rest methods system of treatment without glasses; the fools are those who continue to waddle in the pool of failure left behind by idiotic professions such as optometry, that knows nothing in the real cure of vision.
No I am not going to go away and I am not an little egotistical idiot. I don't care if no one wants to have anything in common with me, but I know I don't want to have anything in common with you stupid man.

Zetsu - 05 Oct 2007 15:21 GMT Well if you were being sarcastic then howcome in your next post you wrote that pantoscopic tilt plays an important role for farsighted correction? That means you weren't being sarcastic.
And I'm not an idiot you're the idiot so be quiet. My motives in posting might be irrelevant, but pclar was the one who questioned them in the first place so it was reasonable for me to object.
Neil Brooks - 05 Oct 2007 15:27 GMT > Well if you were being sarcastic then howcome in your next post you > wrote that pantoscopic tilt plays an important role for farsighted > correction? That means you weren't being sarcastic. No, of course it doesn't. You're just an idiot. You "prove" things in the same irrational way that Otis does. That should scare the HELL out of you.
> And I'm not an idiot you're the idiot so be quiet. Actually, if YOU'd stop posting on this site, then YOU'd stop looking like an idiot.
Zetsu - 05 Oct 2007 15:37 GMT Really I don't care all that much how it makes me look or if it makes me look like a big idiot, posting on this site. I will continue to slap people out of their slumber - it is a dirty work, mind well, but someone has to do it. If no one does it then people remain in their sleep, following the ludicrous treatments of optomety like blind follower after blind follower. People will continue to suffer under the incompetence of nonsense quackeries such as glasses and LASIK.
>That should scare the HELL out of you. What truly scares me is your idiocy.

Never mind. Don't answer that. YOU wouldn't.
Kevin: you need a very good refraction -- possibly even by an optometrist who specializes in "low vision optometry" and who understands issues like vertex distance, pantoscopic tilt, etc. When your Rx is over 5.00d, the little things can make a big difference.
Here's the usual disclaimer. Looks like it's needed again:
Sorry. Rishi Giovanni Gatti (Zetsu), Lena102938, and Otis Brown are trolls who haunt s.m.v.
Rishi has published, and is trying to sell worthless books.
Otis is pathologically dishonest and actually hurts people. Following his advice can induce double vision in those not working closely with an eye doctor.
Lena102938 uses anti-eye doctor rhetoric as a substitute for ANY actual information. It seems she now has to wear glasses and has developed a pathological (and ILLOGICAL) resentment toward the industry that "foisted these glasses upon her."
You'd do well to ignore them and wait for responses from the caring, compassionate eye doctors who DO also participate in this site.
otisbrown@pa.net - 05 Oct 2007 03:13 GMT Dear Kevin,
A caring, compassionate eye doctor wrote you a highly accurate prescription after a complete review.
You have the written prescription (as required by law) in you hand.
You can fill your prescription anywhere you wish.
Best,
Otis

Can you tell me about the impact of vertex distance on accuracy when an Rx of +5 is written?
In other words, if the vertex distance is not accurately taken into account WHEN THE refraction is performed, AND is not noted on the Rx, can you tell me how much difference (in diopters) results from, say, a 10mm discrepancy in vertex distance?
Thanks.
Kevin: since this is the kind of thing that Otis seems to know nothing about ... and cares even LESS about ... then:
a) You may want to review the following to see why I point it out, and
b) You may want to simply ignore Otis
c) Actually, I'd do both

I don't know Otis or Zetsu. I do know that Zetsu kept posting in almost every post, something about "you can control/fix your eyesight with your mind, so forget about eyeglasses or lasik".
Otis, I was looking for some answers,. I did ask for recommendations too though so thanks for plugging zennioptical.com website, I'll consider it with the rest after I figure out what else I'm missing other than PD.
Neil - I decided to go with Trivex b/c of it's high Abbe value and good optics. However, none of the local optometrists (that I called) sell Trivex AND have the frames that I want.
Will wait for someone to chime in, although a lot of people seem to advocate local practioners.
Thanks,
Kevin
Ed - 05 Oct 2007 04:55 GMT Two months ago, I took a chance and bought 2 pairs of glasses from Zenni Optical and was quite pleased. Unfortunately, you don't get to select the brand of lenses. My wife got progressive bifocals with photochromatic lenses for a total of $89, and I got a pair of lined bifocals with antireflective coating for $30. Shipping for both pair was $5. The frames appear cheaply made, but looked good. Oh, and it took 2 weeks to get the glasses. The lenses were perfect. No scratches and the prescriptions were right on!
I've read many, many reviews of Zenni and the consensus seems to be that IF they get it right, you'll be more than pleased. But if you have any kind of problem, good luck getting it resolved in a timely fashion, if at all!
By the way, does anyone here know where Zenni gets their lenses?

It's important to note Kevin's prescription, though, when considering the relative merits of online ordering.
If he wanted +1.50d readers, then ... sure. But his high plus Rx -- IMHO -- requires a little more attention to detail AND the flexibility for service after the sale that you reference.
Not every problem with imperfect refraction CAN or SHOULD BE dealt with at the frame fitting level.
That's the primary reason for local, highly qualified optometrist involvement.
Kevin: how "local" is "local?" Perhaps with a bit of digging, you could find somebody who's at least /reasonably/ close. For the one or two trips that you might need to make, I'm thinking it would pay big dividends....

I live in a metropolitan area so local is basically a 30mile radius I guess. Then again it's just optometrists who were referred to me by family and friends and some that advertise locally.
If PD and Vertex can be measured by a local optometrist or my opthamologist I wonder if I would be covered. I'm definitely not looking at $39.99 a pair. So far the numbers I have in mind (from looking at multiple online places, including Ebay) are about $120 where I supply the frame.
The problem found when I went to Zenni* or 39Dollar* they don't really specify the material of the lens. I know for sure I don't want Polycarbonate, that's what my Lenscrafters glasses were before I returned them, horrible optics. So I need either Hi Index plastic or Trivex lenses.
Thanks,
Kevin

Again (and I'm not an expert; just another fairly farsighted guy), at your/our level of Rx, I'd want it done right. If you reviewed the article cited as a .pdf, you can readily see how a few millimeters can make a significant difference in your Rx.
Your average 55 year old, needing +1.50 reading glasses has no real reason to spend more than drug store money ... unless THOSE glasses are inadequate or unsatisfactory. YOU (or I), on the other hand, SHOULD gain some awareness of ABBE value, index of refraction, etc.
Depending on your age, particularly if you've had a cycloplegic refraction (I'd recommend it if you're under 40-45 years old), you're likely to keep a pair of glasses for a few years. Why economize when comfort, clarity, and crispness of vision CAN be enhanced with a really excellent Rx AND high-quality lenses.
If you're interested, perhaps you could offer which metro area you're in. Maybe somebody knows somebody there, or ... if nothing else ... might be able to point you toward a "low vision optometrist" with particular expertise in meticulous refractions.

We're up to about three solid trolls here, right now (You, Otis, and Atchoo). The big question is, really, which of you will cause medical harm to somebody next?
Care to guess ... Lena? You seem to do that with great ease.

Though, come to think of it, you (and Otis) are wrong at an alarming rate. Perhaps that's not good ... not healthy.
He's a +5 and a +5.25. READ a little. THEN shut up.

You already know your Rx can perform poorly when filled by an inexperienced optician at big box optical, so it shouldn't surprise you if I said an order taker with no experience, who can't even observe the relationship between the frame, lens, eyes, and head, will cause even more problems then you've experienced already.
The solution is to upgrade, not downgrade the skill and experience of the optician. Start looking at MD and OD offices and clinics, and use the knowledge that you've acquired online to ask tough questions, like issues with chromatic aberration (you don't want it- or more accurately not to much) and aspheric designs (this you do want!). They will also be able to fit the lenses into your own frame, if the frame is suitable for your Rx and fit. Make sure that any frame you purchase elsewhere can be returned for a full credit just in case there are any issues.

Thanks for your response, was waiting for it :-)
So, I guess you're saying that ordering online is probably a really bad idea. My issues with the glasses from Lenscrafters was the wrong material, namely Polycarbonate that caused the chromatic and spherical abberation. I was looking at getting Trivex or hi-index plastic (Seiko / Nikon) that would have a higher abbe value and reduce those abberation issues.
However, if I were to go to an online place the only information they have would be what I send them which is basically prescription and PD. In order for your local opthamologist/optometrist to make a pair of glasses for you, what else do they measure before setting them up? Granted, what it is they do measure is probably not something I can just measure and send to an online place.
Really appreciate your advise, as opposed to the other 40+ babble responses I've been wading through :-)
Thanks,
Kevin

Might be ok for a back-up pair, although your optician could probably make a bare bones pair for not much more than what it will cost online.

I like Trivex, but whatever you choose, make sure that it's an aspheric design.

PD must be monocular; ie, for each eye individually, and the vertical optical centers should be checked for proper position and adjusted if necessary. Frame should not be rimless, the nasal lens thickness should not interfere with the pads or pad arms when adjusted properly, should be adjustable for panto, sized for sufficient field of vision but small enough to minimize thickness/magnification and weight, and so on.

>Thanks, > >Kevin Your welcome. Keep in mind, the size and shape of the frame will strongly influence the weight and thickness of the lenses; try to use a smaller frame that minimizes decentration, and choose a shape that has rounded corners and is as symmetric as cosmetics and fashion will allow.
