Contact lenses not well adjusted

Discussion in 'Contact Lenses' started by mikesmith9999, Jan 1, 2006.

  1. I was disappointed when I received my new disposable contact lenses
    because I see blurry from the left eye. I can still read, but sometimes
    with difficulty. In 6 months I will go for another eye exam, but will
    visit a different doctor this time. Should I go as soon as possible
    instead? I don't have headaches or any other obvious problems. Thanks.

    Are you happy with blurry vision?

    If not, I would go back to the prescribing doctor and discuss the
    problem with him/her.

    Not much downside to that....

    Happy New Year!

  4. I don't mind seeing blurry when I drive. The most annoying thing is
    when I need to read something in a dark place like in the car or at the
    restaurant, or at work where I look at a computer screen all day.

    ANSI Z80.20 and ISO 8321 standards lay down tolerances for contact lens
    power. For 0.00D to 10.00D, the tolerance is +/- 0.25D, and above 10.00 the
    tolerance is 0.50D.

    In manufacture, lenses that fall outside of these tolerances wil probably be
    reassigned.

    In the US certainly, incorrect labelling of lens power is a recall situation

    ick... We've been working on fitting my trifocals for months
    now and we're making .25 adjustments. Doc was even
    considering a .125 this last time if they could do it... Maybe
    that's why some of the adjustments have bought some
    surprising results. By the standards we could order a
    -.25 difference and end up with a -.75 actual.

    I would hope with computer controlled manufacture that,
    in practice, tolerances are much tighter than the standards.
