Two general questions about contact lenses

Discussion in 'Contact Lenses' started by Blasterbot5555, Aug 28, 2007.

  1. Since you were all so helpful last week regarding my question about
    the way my eyeglass prescription was written, I thought I'd ask about
    contact lenses. Two questions:

    1) Because of my astigmatism, I need to wear toric lenses, which I've
    been doing for awhile. I was interested in trying colored contacts and
    the doctor gave me some trials of Freshlook Colorblends (apparently
    the only colored toric lens), which I tried but didn't like for a
    bunch of reasons. Anyway, I asked about getting a different brand of
    colored contacts in a no-power version purely for cosmetic reasons and
    was told that to do that I'd need another contact lens fitting

    So my question is...why? Assuming the base curve and diameter of the
    new brand is the same as the lenses I've been wearing, is another
    fitting really neccesary?

    2) In line with the above...I just checked the internet to see if I
    could buy my clear toric lenses through any of the online retailers.
    Apparently, the brand I've been prescribed is made by a company called
    Saufron that only sells to eye care professionals. Which means they're
    not available through internet retailers and I'm stuck paying whatever
    my local eyecare store decides they're worth.

    While I'm quite happy with the lenses, I must admit that I'm more than
    a little annoyed about not having the option to shop for a better
    price. Toric lenses are not inexpensive and I'm not wild about this
    feeling that I was fitted with these in an effort to keep my cash
    rolling into an particu;ar eyecare store. Advice?

    is the prescription brand-specific? I thought you could use the
    prescription for any brand.

  4. A toric lens is surely going to be a hard lens material (otherwise it
    would not correct your astigmatism). Therefore i am assuming the lens
    material will not be completely gas permeable and therefore the health
    of your eye is reliant on a good flow of tears between the contact
    lens and the cornea.

    Each manufacturers lenses will likely have different curves no matter
    what it might seem like from the number on the box.
    Toric lenses are not inexpensive and I'm not wild about this
    I think you are being a bit overly cynical and a bit cavalier with
    your eye health.. If you are requiring a hard lens material the fit
    is likely to be that much more critical than for the softer gas
    permeable types.

    Either way no contact lens can ever create the same healthy conditions
    that your eye needs as can an eye with no contact lens placed upon
    it. Contact lenses can never be the best healthy choice for the
    long term health of your eyes so if you are going to wear then having
    the best possible fit makes sense.

    I am not a practitioner but I have done research on contact lens
    It is likely that different brands of contact lens will have different
    properties (wettability) which means they may interact with your tear
    differently. So one type of lens could feel more dry than another even
    they are both soft lenses. This may also affect how they move on the
    when blinking. A fitting session will probably check this.

    Many people buy contact lenses successfully over the internet but it's
    important to make sure you still visit the practitioner for aftercare
    checkups. It would therefore probably be best to find another optician
    who is happy to provide an aftercare only service. It's a little
    because they probably make most of their money by selling contact
    lenses (and glasses) rather than the aftercare so the internet
    are doing very well because they don't have to subsidise the
    But as I say, many people manage so it must be possible, though
    with a different brand of contact lenses.

    Did you mean Sauflon (instead of Saufron)? I'm not sure where you
    are, but in the UK they supply Tesco's supermarket which may
    be a cheaper option now that some of the supermarkets have
    their own opticians department.

    I suggest that you stick to your own little niche of psychology and
    vision, since you know zero about contact lenses.
    wrong. there are indeed soft disposable toric contact lenses. that's
    what most contact wearers with astigmatism wear and what most are
    fitted with.
    wrong. there are oxygen-permeable soft toric lenses that are not
    dependent upon tear flow to sustain corneal health
    and i think you are a bit cavalier about offering advise to someone
    about a subject that you have no knowledge of. why do you come to
    this forum and start serving up advise about contact lenses?

    no. contact lenses from one manufacturer are not equivalent to
    contacts offered by another. the plastic is different. the edge
    design is different. the thickness is different, etc.

    Also, one may deform easier than another when blinking
    due to different mechanical properties.

    Excuse me, in that case :
    It is different, but I do not think that her OD think the same.
    He prescribed not the best or more comfortable for her.
    He prescribed the brand which he sells.

    No some rigid materials more permeable than soft.
    Hint is even in the name RGP is a Rigid Gas Permeable

    They try to make it look like brand-specific
    Just letting you know

    As a rule they are not so particular in prescriptions about
    design :edges and so on
    Example : bausch&lomb multifocal it is the "One size fits all" (One
    base curve and radius)
    Main statement "You will use to it"

  12. about a subject that you have no knowledge of. why do you come to
    this forum and start serving up advise about contact lenses?

    Since the poster felt he was being ripped off by what he was told it
    makes some sense for a lay person to say from a common sense point of
    view that he was not likely to be doing the best thing by being so
    cavalier with his eyes by attempting to find lenses from other sources
    and where there was no fitting service provided.

    And even if my technical guesses were wrong no gas permeable lense can
    ever be as good as no contact lens and there must be risks associated
    with the use of contact lenses which are hard to quantify for any
    given wearer.

    I assume you and Mike are not disagreeing with these points?

    Hello Blasterbot. I will try to help with your questions.
    if you have been fitted in a different lens than Freshlook, and the
    eye doc has not seen you wearing Freshlook before, then he must
    examine you with the Freshlook lenses in your eyes in order to be sure
    that they fit properly. so in most cases when you ask for a
    prescription for another type of contact it truly does mean that the
    eye doc will need to schedule for another follow-up and in some
    offices that could mean that it might cost you more $$. however, in
    this specific case, if your eye doc has already seen you wearing
    Freshlook Toric lenses then he already knows if they fit properly or
    not since in fact their specifications are exactly the same as
    Freshlook colors (same plastic, diameter, base curve, edge design,
    etc.). so in my practice I would automatically approve your request
    for Freshlook colored lenses based upon my evaluation with the toric
    lenses earlier.
    I understand your annoyance. this is an old trick that a lot of eye
    docs still try to pull in order to make additional profits by being
    the sole source of the contacts that they fit you in. I am afraid
    there isn't much you can do about it now. Just learn a lesson-- the
    next time you get fitted in contacts tell the eye doc that you want to
    wear a brand of lens that is commonly available from a variety of
    sources-- not just his/her office. You might actually make a short
    list of lenses that you can get online and then present that list to
    your doctor and ask him/her to consider those lenses, if appropriate
    for your eye health, before considering others. I do not sell any
    contacts in my practice so I am free to prescribe whatever I think is
    best for the patient or whatever the patient prefers-- assuming that I
    agree that the lens is not harmful to the patient.

    PClar, I don't understand.

    Are you saying that eye doctors directly profit from selling contact
    lenses? I thought they have a fixed salary? And I thought that the
    money which they gain from selling contact lens products all go to the
    actual company?

    I just don't see what incentive there would be for the eye docs to
    want to decieve their patients into buying their products.

    Or do they profit indirectly?; i.e the more they sell the higher
    reputation they get and the higher reputation means higher chances of
    promotion or salary upgrade from their boss? Please please could you
    explain it.

    Sauflon is an old custom manufacturer of contact lenses. Many toric
    lenses are still custom made and are not available in disposable
    format. In your case, going to a mass produced lens may or may not
    provide the same comfort or clarity. Just because Walmart does not
    sell them doesn't mean that your eye doctor has done anything wrong.
    Your doctor just may have had good luck using that product. It's like
    buying shoes.

    If it is custom made , sorry, disregard all my posts about "sales".and

    No, actually toric lens are usually soft contacts. They are aspherical
    and have to have a certain orientation. RGPs for astigmatism are
    usually spherical.
    Actually, RGP (rigid gas permeables) breathe better than soft lenses.
    That seems counterintuitive, but that's the fact.

    That's perhaps too broad a generalization. It depends on a number of
    things, such as lens diameter, DK, thickness, etc. Soft lenses like
    Focus Night and Day are difficult to beat in terms of oxygen
    Dr. Leukoma, Aug 29, 2007
  19. Actually, the trials I got were for the straight Colorblends, not the
    toric version. I think the idea was that I was supposed to pick a
    color first. Unfortunately, I didn't like any of them.

    My point is that colored contact lenses don't seem to come in a myriad
    of base curves and diameters. Freshlook Colorblends come in exactly
    one size. Acuvue 2 Color (the brand I wanted to try) comes in 2 base
    curves but only one diameter. Given that, I'd assume that the fits on
    these things for most people is reasonably close but not optimal. If
    that's the case, I'm not really seeing the point of another fitting.
    Why should I need to pay twice? I've already done a contact lens
    fitting. Assuming we now know what size and power toric lens is
    perfect for me, what difference does it make who the manufacturer is
    or where I choose to purchase them?

    Reading the responses here, I'm starting to wonder if I was fitted
    with the Sauflon contacts because they were best for me or out of some
    crass profit motive. And that REALLY bothers me.
    Blasterbot5555, Aug 29, 2007
  20. These are two week disposable soft lenses. They come 6 to a box and
    cost roughly $50 per box. The doctor had the trials right there for me
    to try the day I was examined. One was slightly off and he needed to
    order a slightly different power. It was there waiting for me the
    Tuesday after the Saturday I was examined. So I'm rather doubting that
    these lenses are custom-made. And Sauflons's website touts the fact
    that their products force patients to keep coming back to the eyecare
    store since they're not available anywhere else.

    I probably should count my blessings. The first eye doctor I saw
    (which sent me running to find a new one) told me with a straight face
    that all toric lenses were custom-made and cost $250 a box, and then
    proceeded to practically insist that I buy them right then and there.
    I didn't know enough about the subject at that time to actually
    suspect that she wasn't being entirely honest, but something about her
    hard sell approach made me nervous.
