    HI ( newbie)

    Basically, I have recently visited my optometrist and he gave me ( as i
    expected a prescription for glasses)

    but what i cant find out is what the prescription details mean....

    so i was kinda hoping if anyone here can make sence of them for me, point me
    in the direction of a suitable www. page.


    anyways here is what i got


    Right Eye

    SPH CYL AXS PRI BSE
    DIST -1.25 +1.00 90 --- ---

    NEAR ----- ----- ---- --- ---



    LEFT Eye

    SPH CYL AXS PRI BSE
    DIST -1.50 +1.00 90 --- ---

    NEAR ----- ----- ---- --- ---


    He said somthing about my having an astigmatisiam, which figures with what i
    can find,

    trouble is the bloke who did my eye test never said what i should use the
    glasses for, reading, driving, all the time, using the computer?

    im guessing as i first noticed my apparent need for sight correction when
    using the computer ( yea i slapped the monitor for being out of focus!!! )
    then i guess i would need to use them for computing!!!

    anyways

    TIA

    Tom

    Tom Burton put fingers to keyboard and typed...
    Prolly something along the lines of 'understanding prescription sph cyl'

    but most of these IMHO are not very intuitive for the layman who wants to
    know what the numbers mean in more detail. Anyhoo, heres one that cropped
    up:

    well until then not knowing what a sph or cyl is i might have ended up
    barking up the wrong tree.

    but anyway thats an excellent site

    thanks

    No problem mate, glad to see your typing has improved - are you wearing
    your specs now ;O)

    I was half-tempted to make a snide comment about the following, and I
    quote:

    'or again point me ina suitable direction, im normally pretty hot with
    google, but perhaps im searching the wrong terms of srtings of terms!'

    :eek:P

    Dear Tom,

    These minus lenses were prescribed for your
    distant vision. The prescription indicates
    that you could only read about 20/70 to
    20/100 on the eye chart. Thus these
    are "nearsighted" glasses.

    I regret that you were given no instructions
    for the use of these lenses. Look at distant
    objects. Blurry? Now look through your
    minus lense. Much sharper, right?

    That is why you were given these lenses.
    You will need them for driving a car.

    At all other times you do not need them.

    For some more "engineering" opinion you might
    enjoy reading my site:

    [nods encouragingly - i belive you :) ]
    uh uh

    so just to clarify, im guessing i should use these lenses for using the
    computer as this is when i noticed the inital problem!
    but as there has been so argument as to otis's post, should i be wearing
    these lenses for driving, all the time,

    or should i just wear them and find what is comfortable for me?

    Thanks again

    Tom

    Dear Nipidoc,

    Thanks for your commentary.

    The limits for flying are that you have
    20/20, and astigmatism of less than
    2 diopters.

    There has been a continuing debate as
    to the wisdom of "correcting" astigmatism
    in a person that has 20/20 vision.

    It would be of value to know what this
    person reads on the standard eye chart.

    I will forward your commentary to
    Dr. Steve Leung for his thoughts.

    Best,

    Otis

    Not indicated on my licence but then agian there is no requirement for me to
    tell them, so ill save the £38 have another pizza and wear them anyway!

    That said i might be upgrading my licence to D1 and C1 or C1E/R soon, but a
    quick glance over them asks only for my prescription details on the
    application.

    Now that all the bullshit has been said, be aware of this: glasses
    will make you see better (to some extent) BUT they WILL make your
    eyes get worse and worse.
    The why is simple: you have imperfect sight because you (consciously
    or unconsciously) strain to see objects.
    This strain to see is what causes the eye muscles to incorrectly tense
    and modify the shape of the eyeball. If you wear glasses, to see well
    through them you have to reproduce that muscle tension. Your mind
    will fight against this silliness and you will have headaches and
    such. They will say that you have to get accustomed to the devices.
    This equals to force upon you a bad habit of straining to see.
    And you'll get worse or remain with imperfect vision (at best).

    So, "what should I do?" you'll ask.
    Simple: close your eyes and rest them more often than you do.
    Remember that if you have imperfect vision is because of your
    straining to see objects all at once, while to see perfectly you
    have to see what you are not regarding worse than what you
    are looking at, and shift your point of fixation.
    When you are resting your eyes, use your imagination to visualize
    mentally something that you can remember perfectly (an object, a
    face, something pleasant and relaxing).

    Another way to get rid of the strain to see objects is to
    regard a familiar small letter everyday. The smaller the better.

    This is simply common sense. Glasses are nonsense.

    Get as much light as possible on your closed eyes and set a
    small font on your computer: large letters are injurious to the
    eyes because of the tendency to see them all at once instead
    of looking at them seeing one part best (blacker) at a time.

    They will say that this is bullshit just like I said that their was.
    I leave it to you to wear glasses and **** up your mind and
    eyes or to try these simple common sense things and report
    here what happens.

    Remember one thing: the solution to imperfect sight is one
    and only one: relief from the strain to see.

    DVLA rules states that you must be able to read a number plate at 20.5Meters

    well i tried that earlier dusky condiftons/failing light withou correction
    and i can read it no problem, thus the DVLA say i can drive no problem.
    which i might well be prosecuted for..... Death By
    Dangergous/Wreckless/Careless Driving delete as aplicable in the UK
    No, im inclined to use the corrective device when its rqd, thus when i
    collect my glasses i shall quiz the chappie further on the intended use for
    them.
    i was thinking of trying evaristos method of closing my eyes whilst doing
    70mph on the M-Way
    no seriously i might go as far as sitting in the car parked up and putting
    the glasses on and off, in differing conditions to see what difference it
    makes.....

    You not only are asking for flame wars, but you show your uttermost
    ignorance of the Bates' work. Please read his book and not all the
    shit that they like to call Bates' work.

    There is no one Method, but it is a simple discovery and a set, a
    system, of useful things to do to get the hint of what relaxation
    from strain to see is.

    What "cures" is a proper use of the eyes.

    The fact that people got improvement is simply a demonstration
    of what to reduce glasses use could do. BUT improvement is not
    enough, Bates talked about complete cures, and he was right.
    You cannot strain to see and see.

    Tom, I'm glad you still can see what the strain to see could do
    to these people, not only to their eyes but to their mind as well.
    If to all this you add the frustration of not having been able to
    get results but hoping to get well you have... well ...flame wars !

    Their problem is that they are sticking to their ideas in a religious
    fanatic way (they talk about devotees .. wtf?) and behave in a way
    that shows their way of (not) seeing things, namely straining.
    This exact way of thinking is what prevent them to see well.

    I have no problem with those people, because I know what the
    truth is (a very simple one) and I have demonstrated and been
    benefited by it. So I can only feel sorry for those helpless souls.

    There are lots of people who are devoted to improving their vision and
    First of all I don't understand the reasonableness of wearing
    anything.

    On th contrary I say that glasses have to be destroyed if one is
    serious in "vision recovery" (the right term is "strain to see
    relaxing").

    If you cannot drive without glasses what you want to do is extremely
    simple: do not drive until you are cured! Not wearing glasses has,
    especially in modern society, the advantage of having you be more
    determined in curing yourself.
    This poor woman is obsessed with this "driving thing" for this
    reason: she doesn't understand how to cure herself (this is common)
    and uses the driving obligation as an excuse to not get rid of the
    glasses or do whatever has to be done to get rid of them.
    She feels helpless without her precioussssssss and fights whoever
    wants to get them away from her, finding every excuse to not do the
    right things.

    Hey, wait a minute, didn't you post the FAA licensing requirements a month
    or two ago and, as I remember, the requirement was 20/20 WITH GLASSES and no
    restriction on astigmatism.

    Dear Judy,

    I have posted the FAA requirements on my site.

    The MILITARY requirements are 20/20 with no glasses.
    (therefore a focal status of from zero to +1.5 diotpers).

    The limit is 2.0 diopters. Therefore they do not require
    (nor want) ASTIGMATISM "corrected". They just require
    20/20 and NO GLASSES.

    The FAA has made steady changes to its requirements.

    It used to require 20/100 vision, corrected to 20/20.

    If you are going to wear glasses to achieve 20/20, then
    yes crank in some astigmatism if that makes you happy.

    Hope this clarifies. I always request spherical lenses,
    provided that astigmatism is less than 2 diopters.

    Best,

    Otis
