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!

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.
