Question on eye sight check up v contact lens check up

    Hopefully someone can answer these questions for me as I don't really
    trust my local optician, specsavers (England).

    I recently had an eye sight test (with an optometrist) and a contact
    lens check (with someone I don't think is an Optometrist). The
    optometrist changed my prescription from:
    left right
    -3.50 -5.75

    -4.00 -6.50

    I decided I wouldn't bother getting my spectacles refitted (which
    would have cost £200), and expected my contact lens strength to change
    in relation to the sight test.

    However when my contact lenses arrived (through post every 3 months)
    the lenses prescription remained the same at:
    -3.00 -5.50

    When I spoken to specsavers they said the Optometrist only recommended
    changing my spectacles not contact lenses. To me this seems a little
    odd. Surely if your eye sight changes it affects both lenses and
    spectacles. Furthermore they recommended I re-visit them to have a
    contact lens check again, but i don't think the person who does this
    is even a optometrist...

    Is this sort of thing common practice or am I worrying for nothing?

    If your optometrist did not check your contacts, he/she could not write a
    prescription for them. The power of contact lenses is determined by
    refracting the eye with the contacts in place. Did you tell the person
    checking your contact lens that your glasses prescription had changed?

    You should be asking the contact lens checker why they didn't check the
    power of the lens by over refraction during the original check up.

    Only if you had a 'contact lens aftercare' as well - normally they
    wouldn't change your contact lens specification unless you had one of
    these with an optometrist or contact lens practitioner.
    See above.
    Yes, such a change usually results in a modified contact lens
    prescription as well.

    Perfectly reasonable request, they have to perform an aftercare check,
    including an 'overefraction' (i.e. checking your prescription with
    contacts in place) if it wasn't done with the eye examination.
    Again, a contact lens examination can also be performed by a qualified
    contact lens practitioner.

    I'm new to contact lens, I'm having my contact lens fitting right now.
    I'm sure this might happen to me down the road. The problem here is on
    one hand they recommend a re-visit to have the contact lens check.
    But, they keep sending him contacts with the old prescription which
    might be physical fit but not provide good vision. Is this a
    For glass/contact wearer, should we specify both glass and contact
    update on every check up or is it automatically done to both. Can we
    just have the contact update without the glass update. Maybe this is
    doctor/shop depentent.
    Also, do we have any input on what brand of contact to try during the
    fitting. Do most doctor can prescribe most common brand? I'm trying
    out Aspheric contact from Cooper Vision right now.

    It is in a way, but we're talking real world logistics here. The OP has a
    scheme set up whereby the lenses are sent automatically mailed to him. As
    with most things in the modern world, the whole process is controlled by
    computers. In this instance (as it is in a lot of cases), only a
    spectacle refraction was performed at the time of the patient's visit.

    In order change the specification of the lenses sent through the mail,
    the (probably separate) contact lens computer record would have to be
    amended. This wouldn't normally be done unless authorised following a
    contact lens aftercare appointment.

    Most places wouldn't perform a contact lens check unless an eye test had
    been perfomed recently (normally within 1 or 2 years). If there has been
    a recent eye exam, than a contact lens check can be performed without
    another full refraction.
    I'm sure your contact lens practitioner would be happy to hear your
    input, unfortunately a lot of the big chains only supply a limited range
    of lenses.

    Thanks for the replies, my vision seems ok with my lenses so I'm sure
    it's fine. I'll make sure I mention this on my next visist though.
